116-625: Stainmore is a remote geographic area in the Pennines on the border of Cumbria , County Durham and North Yorkshire . The name is used for a civil parish in the Eden District of Cumbria , England, including the villages of North Stainmore and South Stainmore. The parish had a population of 253 in the 2001 census, increasing to 264 at the Census 2011. Stainmore Forest stretches further east into County Durham, towards Bowes . Stainmore

232-628: A hernia . Spinal stenosis is a narrowing of the spinal canal which can occur in any region of the spine though less commonly in the thoracic region. The stenosis can constrict the spinal canal giving rise to a neurological deficit . Pain at the coccyx (tailbone) is known as coccydynia . Spinal cord injury is damage to the spinal cord that causes changes in its function, either temporary or permanent. Spinal cord injuries can be divided into categories: complete transection, hemisection, central spinal cord lesions, posterior spinal cord lesions, and anterior spinal cord lesions. Scalloping vertebrae

348-412: A central cavity, the central canal . Adjacent to each vertebra emerge spinal nerves . The spinal nerves provide sympathetic nervous supply to the body, with nerves emerging forming the sympathetic trunk and the splanchnic nerves . The spinal canal follows the different curves of the column; it is large and triangular in those parts of the column that enjoy the greatest freedom of movement, such as

464-449: A curve, convex forward, that begins at the axis (second cervical vertebra) at the apex of the odontoid process or dens and ends at the middle of the second thoracic vertebra; it is the least marked of all the curves. This inward curve is known as a lordotic curve. The thoracic curve, concave forward, begins at the middle of the second and ends at the middle of the twelfth thoracic vertebra. Its most prominent point behind corresponds to

580-413: A neural arch, while the haemal arch is found underneath the centrum in the caudal (tail) vertebrae of fish , most reptiles , some birds, some dinosaurs and some mammals with long tails. The vertebral processes can either give the structure rigidity, help them articulate with ribs, or serve as muscle attachment points. Common types are transverse process, diapophyses, parapophyses, and zygapophyses (both

696-456: A region can vary but overall the number remains the same. The number of those in the cervical region, however, is only rarely changed. The vertebrae of the cervical, thoracic, and lumbar spines are independent bones and generally quite similar. The vertebrae of the sacrum and coccyx are usually fused and unable to move independently. Two special vertebrae are the atlas and axis , on which the head rests. A typical vertebra consists of two parts:

812-399: A remnant of the notochord. Reptiles often retain the primitive intercentra, which are present as small crescent-shaped bony elements lying between the bodies of adjacent vertebrae; similar structures are often found in the caudal vertebrae of mammals. In the tail, these are attached to chevron-shaped bones called haemal arches , which attach below the base of the spine, and help to support

928-438: A result of lifting the head and the lumbar curvature forms as a result of walking. The vertebral column surrounds the spinal cord which travels within the spinal canal , formed from a central hole within each vertebra . The spinal cord is part of the central nervous system that supplies nerves and receives information from the peripheral nervous system within the body. The spinal cord consists of grey and white matter and

1044-672: A series of geological structures whose overall form is a broad anticline whose axis extends in a north–south direction. The North Pennines are coincident with the Alston Block and the Yorkshire Dales are coincident with the Askrigg Block . In the south the Peak District is essentially a flat-topped dome. Each of the structures consists of Carboniferous limestone overlain with Millstone Grit . The limestone

1160-785: Is bordered by the foothills of the Lake District , and uplands of the Howgill Fells, Orton Fells, Border Moors and Cheviot Hills. The West Pennine Moors, Rossendale Valley and Forest of Bowland are western spurs, the former two are in the South Pennines. The Howgill Fells and Orton Fells are sometimes considered to be part of the Pennines, both inside the Yorkshire Dales National Park. The Pennines are fringed by extensive lowlands including

1276-413: Is classed as a spinal disease or dorsopathy and includes the following abnormal curvatures: Individual vertebrae of the human vertebral column can be felt and used as surface anatomy , with reference points are taken from the middle of the vertebral body. This provides anatomical landmarks that can be used to guide procedures such as a lumbar puncture and also as vertical reference points to describe

1392-416: Is curved in several places, a result of human bipedal evolution . These curves increase the vertebral column's strength, flexibility, and ability to absorb shock, stabilising the body in upright position. When the load on the spine is increased, the curvatures increase in depth (become more curved) to accommodate the extra weight. They then spring back when the weight is removed. The upper cervical spine has

1508-751: Is drained by the River Belah to the west and, to the east, the River Balder , Deepdale Beck , and the River Greta . It is crossed by the Roman road from Bowes to Brough , now part of the A66 , and formerly by the Stainmore Railway . Each of these lines of communication has made use of the relatively low broad saddle between the higher hills to north and south which is commonly referred to as

1624-742: Is exposed at the surface in the North Pennines, Yorkshire Dales and the Peak District. In the Dales and the White Peak , limestone exposure has caused the formation of large cave systems and watercourses. In the Dales the caves or potholes are known as "pots" in the Yorkshire dialect . They include some of the largest caves in England at Gaping Gill , more than 350 ft (107 m) deep and Rowten Pot , 365 ft (111 m) deep. Titan in

1740-432: Is shallow, and by the laminae and transverse processes in the thoracic region, where it is deep and broad; these grooves lodge the deep muscles of the back. Lateral to the spinous processes are the articular processes, and still more laterally the transverse processes. In the thoracic region, the transverse processes stand backward, on a plane considerably behind that of the same processes in the cervical and lumbar regions. In

1856-456: Is sparsely populated by English standards. Larger population centres are in the foothills and lowlands fringing the southern Pennine range, such as Barnsley , Chesterfield , Halifax , Huddersfield , Macclesfield , Oldham , Bury , Rochdale , Middleton , and Stockport but most of the northern Pennine range is thinly populated. The cities of Bradford , Derby , Leeds , Manchester , Sheffield , Stoke-on-Trent and Wakefield are also in

1972-412: Is the increase in the concavity of the posterior vertebral body. It can be seen on lateral X-ray and sagittal views of CT and MRI scans. Its concavity is due to the increased pressure exerting on the vertebrae due to a mass. Internal spinal mass such as spinal astrocytoma , ependymoma , schwannoma , neurofibroma , and achondroplasia causes vertebrae scalloping. Excessive or abnormal spinal curvature

2088-531: Is the most important mineral quarried, mainly for roads and cement, while other extracted materials include shale for cement and gritstone for building stone. The springs at Buxton and Ashbourne are exploited to produce bottled mineral water and there are approximately 2,700 farms in the National Park. The South Pennines are predominantly industrial, with the main industries including textiles, quarrying and mining, while other economic activities within

2204-952: Is usually taken to derive from some form of Celtic pen or ben ("mountain, head"). Various towns and geographical features within the Pennines have names of Celtic origin, including Pennington , Penrith , Pen-y-ghent , Pendle Hill , the River Eden , and Cumbria . More commonly, local names result from Anglo-Saxon and Norse settlements. In Yorkshire, Teesdale , and Cumbria, many words of Norse origin, not commonly used in standard English, are part of everyday speech: for example, gill/ghyll (narrow steep valley), beck (brook or stream), fell (hill), and dale (valley). Northumbrian/borders terms are used in South Tynedale, Weardale , and Allendale , such as burn (stream), cleugh (ravine), hope (valley), law (hill) and linn (waterfall). The northern Pennine range

2320-692: The A684 road from Sedbergh to Hawes via Garsdale Head which reaches 1,100 feet (340 m). Further south the A58 road traverses the Calder Valley between West Yorkshire and Greater Manchester reaching 1,282 feet (391 m) between Littleborough and Ripponden , while the A646 road along the Calder Valley between Burnley and Halifax reaches 764 feet (233 m) following valley floors. In

2436-521: The Arabian (breed) can have one less vertebrae and pair of ribs. This anomaly disappears in foals that are the product of an Arabian and another breed of horse. Vertebrae are defined by their location in the vertebral column. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera ( Choloepus and Bradypus ) and the manatee genus, ( Trichechus ), all mammals have seven cervical vertebrae. In other vertebrates,

According to Roger of Wendover , it was where Eric Bloodaxe (d. 954), recently expelled from York, was betrayed and killed, an event which some historians believe to have taken place in a great battle . Ancient monuments include a Roman marching camp at Rey Cross and, immediately east of

2668-468: The Dark Peak with moorlands and gritstone edges, and the White Peak with limestone gorges. The South Pennines is an area of hills and moorlands with narrow valleys between the Peak District and Yorkshire Dales. Bowland is dominated by a central upland landform of deeply incised gritstone fells covered with tracts of heather-covered peat moorland, blanket bog and steep-sided wooded valleys linking

2784-734: The Eden Valley , West Lancashire Coastal Plain , Cheshire Plain , Vale of York , Humberhead Levels and the Midland Plains . The main range of the Pennines start from its southern end at the Weaver Hills in the Peak District. The southern foothills of the range merge into the valley and basin of the River Trent , separating the range from the Midland Plains to the south. The Pennines continue northwards across

2900-564: The Industrial Revolution cross the range: The first of three Woodhead Tunnels was completed by the Sheffield, Ashton-Under-Lyne and Manchester Railway in 1845, engineered by Charles Vignoles and Joseph Locke . At the time of its completion in 1845, Woodhead 1 was one of the world's longest railway tunnels at a length of 3 miles 13 yards (4,840 m); it was the first of several trans-Pennine tunnels including

3016-756: The Mersey (including the Irwell , Tame and Goyt ) flow westwards towards the Irish Sea . On the eastern side of the Pennines, the rivers Tyne , Wear , and Tees all drain directly to the North Sea . The Swale , Ure , Nidd , Wharfe , Aire , Calder and Don all flow into the Yorkshire Ouse , and reach the sea through the Humber Estuary . The River Trent flows around the southern end of

3132-714: The Midland Railway built the Settle-Carlisle Line through remote, scenic regions of the Pennines from near Settle to Carlisle passing Appleby-in-Westmorland and other settlements, some a distance from their stations. The line has survived, despite difficult times and is operated by Northern Rail. The Trans Pennine Trail , a long-distance route for cyclists, horse riders and walkers, runs west–east alongside rivers and canals, along disused railway tracks and through historic towns and cities from Southport to Hornsea (207 miles/333 km). It crosses

3248-731: The National Park . The main economic activities in the North Pennines include tourism, farming, timber and small-scale quarrying, due to the rural landscape. Gaps that allow west–east communication across the Pennines include the Tyne Gap between the Pennines and the Cheviots, through which the A69 road and Tyne Valley railway link Carlisle and Newcastle upon Tyne . The A66 road , its summit at 1,450 feet (440 m), follows

3364-589: The Northumberland National Park (9) sometimes also included. The North Pennines AONB just north of the Yorkshire Dales rivals the national park in size and includes some of the Pennines' highest peaks and its most isolated and sparsely populated areas. Other AONBs are Nidderdale east of the Yorkshire Dales, and the Bowland Fells , including Pendle Hill , west of the Yorkshire Dales. The language used in pre-Roman and Roman times

3480-490: The Peak District National Park . The only significant unprotected gap is the area between Skipton and Marsden . Britain's oldest long-distance footpath , the 268-mile (429 km) Pennine Way , runs along most of the Pennines. Various etymologies have proposed treating "Pennine" as a native Brittonic /Modern Welsh name related to pen- ("head"). It did not become a common name until

3596-782: The Pennine Chain or Pennine Hills , are a range of uplands mainly located in Northern England . Commonly described as the " backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the north of the Midlands to Northumberland in North East England . From the Tyne Gap in the north, the range extends south through the North Pennines , Yorkshire Dales , South Pennines , and Peak District to end near

3712-648: The Stainmore Gap . The summit of the former railway is around 420 metres (1,380 ft) above sea level, though the roads climb to slightly higher elevations. The Gap is coincident with the Stainmore Summit Fault which throws the relatively flat-lying Carboniferous rocks of the area down to the south. It acted as a conduit for Lake District -originated ice to pass eastwards during one or more glacial periods . There are several Regionally Important Geological / Geomorphological Sites (RIGS) in

It was bored for the overhead electrification of the route and completed in 1953. The tunnel was opened by the transport minister Alan Lennox-Boyd on 3 June 1954. It was designed by Sir William Halcrow & Partners. The line

3944-409: The anterior and posterior longitudinal ligaments at the front and back of the vertebral bodies , the ligamentum flavum in deep to the laminae , the interspinous and supraspinous ligaments between spinous processes , and the intertransverse ligaments between the transverse processes . The vertebrae in the human vertebral column is divided into different body regions , which correspond to

4060-433: The intervertebral discs . The notochord disappears in the sclerotome (vertebral body) segments but persists in the region of the intervertebral discs as the nucleus pulposus . The nucleus pulposus and the fibers of the anulus fibrosus make up the intervertebral disc. The primary curves (thoracic and sacral curvatures) form during fetal development. The secondary curves develop after birth. The cervical curvature forms as

4176-412: The paraxial mesoderm that lies at the sides of the neural tube and they contain the precursors of spinal bone, the vertebrae ribs and some of the skull, as well as muscle, ligaments and skin. Somitogenesis and the subsequent distribution of somites is controlled by a clock and wavefront model acting in cells of the paraxial mesoderm. Soon after their formation, sclerotomes , which give rise to some of

4292-436: The sacrum and coccyx are fused without a central foramen. The vertebral arch is formed by a ventral pair of pedicles and a dorsal pair of laminae , and supports seven processes , four articular , two transverse and one spinous , the latter also being known as the neural spine. The transverse and spinous processes and their associated ligaments serve as important attachment sites for back and paraspinal muscles and

4408-435: The spinal canal , a body cavity that contains the spinal cord . Because the vertebral column will outgrow the spinal cord during child development , by adulthood the spinal cord often ends at the upper lumbar spine (at around L1/L2 level), the lower ( caudal ) end of the spinal canal is occupied by a ponytail -like bundle of spinal nerves descriptively called cauda equina (from Latin " horse's tail " ), and

4524-411: The spinal cord and the notochord . This column of tissue has a segmented appearance, with alternating areas of dense and less dense areas. As the sclerotome develops, it condenses further eventually developing into the vertebral body . Development of the appropriate shapes of the vertebral bodies is regulated by HOX genes . The less dense tissue that separates the sclerotome segments develop into

4872-420: The 1740s and accepted as genuine until the 1840s. In 2004, George Redmonds reassessed this, finding that numerous respected writers passed over the origin of the mountains' name in silence even in works dedicated to the topological etymology of Derbyshire and Lancashire . He found that the derivation from Bertram was widely believed and considered uncomfortable. In fact, Redmonds found repeated comparisons with

4988-542: The 18th century and almost certainly derives from modern comparisons with the Apennine Mountains , which run down the middle of Italy in a similar fashion. Following an 1853 article by Arthur Hussey, it has become a common belief that the name derives from a passage in The Description of Britain ( Latin : De Situ Britanniæ ), an infamous historical forgery concocted by Charles Bertram in

5104-527: The Anglo-Saxons travelled through the valleys. During the Dark Ages the Pennines were controlled by Celtic and Anglo-Saxon kingdoms. It is believed that the north Pennines were under the control of the kingdom of Rheged . During Norse times the Pennines were settled by Viking Danes in the east and Norwegian Vikings in the west. The Vikings influenced place names, culture and genetics. When England

5220-706: The Border Moors and Cheviot Hills, separated by the Tyne Gap and Whin Sill , along which run the A69 and Hadrian's Wall , are not part of the Pennines but, perhaps because the Pennine Way crosses them, they are treated as such. Most of the Pennine landscape is characterised by upland areas of high moorland indented by more fertile river valleys, although the landscape varies in different areas. The Peak District consists of hills, plateaus and valleys, divided into

6032-514: The Peak District, the deepest shaft known in Britain, is connected to Peak Cavern in Castleton, Derbyshire , the largest cave entrance in the country. Erosion of the limestone has led to geological formations, such as the limestone pavements at Malham Cove . Between the northern and southern areas of exposed limestone between Skipton and the Dark Peak is a belt of exposed gritstone. Here

6148-644: The Pennine Way affects perceptions of the southern and northern extents of the defined area. The southern end of the Pennines is said to be in the High Peak of Derbyshire at Edale , the start of the Pennine Way, but the main range continues south across the Peak District to the Weaver Hills, with its foothills merging into the Trent Valley. This encompasses eastern Cheshire , northern and eastern Staffordshire , and southern Derbyshire. Conversely,

The Trent drains the east and west sides of the southern Pennines, also reaching the North Sea through the Humber Estuary. The Trent and Ouse meet and enter the Humber at Trent Falls . Maximum discharge through the Humber can reach 1,500 m /s (53,000 cu ft/s). According to the Köppen classification ,

6380-442: The Pennines generally have a temperate oceanic climate ( Cfb ) like the rest of England, but the uplands have more precipitation, stronger winds and colder weather than the surrounding areas. Some of the higher elevations have a subpolar oceanic climate ( Cfc ), which may border a tundra ( ET ) and subarctic climate ( Dfc ) in areas like Great Dun Fell . More snow falls on the Pennines than on surrounding lowland areas due to

6496-994: The Pennines longer than it did in the surrounding areas of England. Eventually, the Celtic tongue of the Pennines was replaced by early English as Anglo-Saxons and Vikings settled the area and assimilated the Celts. During the Viking Age Scandinavian settlers brought their language, Old Norse . The fusion of Norse influences into Old English was important in the formation of Middle English and hence Modern English, and many individual words of Norse descent remain in use in local dialects, such as that of Yorkshire , and in local place names. The folklore and customs are mostly based on Celtic , Anglo-Saxon and Viking customs and folklore. Many customs and stories have their origin in Christianised pagan traditions. In

The Aire Gap links Lancashire and Yorkshire via the valleys of the Aire and Ribble . Other high-level roads include Buttertubs Pass , named from limestone potholes near its 1,729-foot (527 m) summit, between Hawes in Wensleydale and Swaledale and

8700-402: The cranial zygapophyses and the caudal zygapophyses). The centrum of the vertebra can be classified based on the fusion of its elements. In temnospondyls , bones such as the spinous process , the pleurocentrum and the intercentrum are separate ossifications. Fused elements, however, classify a vertebra as having holospondyly. A vertebra can also be described in terms of the shape of the ends of

8816-403: The curvatures of the vertebral column. The articulating vertebrae are named according to their region of the spine. Vertebrae in these regions are essentially alike, with minor variation. These regions are called the cervical spine, thoracic spine, lumbar spine, sacrum, and coccyx. There are seven cervical vertebrae, twelve thoracic vertebrae, and five lumbar vertebrae. The number of vertebrae in

8932-442: The dales with mostly pine, elm, lime and oak. On the limestone soils the oak was slower to colonize and pine and birch predominated. Around 3000 BC a noticeable decline in tree pollen indicates that neolithic farmers were clearing woodland to increase grazing for domestic livestock, and studies at Linton Mires and Eshton Tarn find an increase in grassland species. On poorly drained impermeable areas of millstone grit, shale or clays

9048-491: The elevation and distance from the coast; unlike lowland areas of England, the Pennines can have quite severe winters. The northwest is amongst the wettest regions of England and much of the rain falls on the Pennines. The eastern side is drier than the west—the rain shadow shields northeast England from rainfall that would otherwise fall there. Precipitation is important for the area's biodiversity and human population. Many towns and cities are located along rivers flowing from

9164-447: The facet joints restricts the range of motion between the vertebrae. Underneath each pedicle is a small hole (enclosed by the pedicle of the vertebral below) called intervertebral foramen , which transmit the corresponding spinal nerve and dorsal root ganglion that exit the spinal canal. From top to bottom, the vertebrae are: For some medical purposes, adjacent vertebral regions may be considered together: The vertebral column

9280-652: The head streams of the river valleys. Most of the range is protected by national parks and national landscapes (formerly Areas of Outstanding Natural Beauty ). Running north to south, and including the Cheviots, the range is within Northumberland National Park , the North Pennines National Landscape, the Yorkshire Dales National Park , Nidderdale National Landscape , the Forest of Bowland National Landscape, and

9396-432: The length of the vertebral column along the front and back of the vertebral bodies. The interspinous ligaments connect the adjoining spinous processes of the vertebrae. The supraspinous ligament extends the length of the spine running along the back of the spinous processes, from the sacrum to the seventh cervical vertebra . From there it is continuous with the nuchal ligament . The striking segmented pattern of

9512-403: The locations of other parts of human anatomy, such as the positions of organs . The general structure of vertebrae in other animals is largely the same as in humans. Individual vertebrae are composed of a centrum (body), arches protruding from the top and bottom of the centrum, and various processes projecting from the centrum and/or arches. An arch extending from the top of the centrum is called

9628-433: The lower nine are fused in adults, five in the sacrum and four in the coccyx , or tailbone . The articulating vertebrae are named according to their region of the spine. From top to bottom, there are 7 cervical vertebrae , 12 thoracic vertebrae and 5 lumbar vertebrae . The number of those in the cervical region, however, is only rarely changed, while that in the coccygeal region varies most. Excluding rare deviations,

9744-408: The lumbar region, by narrower intervals in the neck, and are closely approximated in the middle of the thoracic region. Occasionally one of these processes deviates a little from the median line — which can sometimes be indicative of a fracture or a displacement of the spine. On either side of the spinous processes is the vertebral groove formed by the laminae in the cervical and lumbar regions, where it

9860-405: The mechanisms involved in vertebral segmentation are conserved across vertebrates. In humans the first four somites are incorporated in the base of the occipital bone of the skull and the next 33 somites will form the vertebrae, ribs, muscles, ligaments and skin. The remaining posterior somites degenerate. During the fourth week of embryogenesis , the sclerotomes shift their position to surround

9976-584: The mountainous terrain in the north. The highest point is Cross Fell in eastern Cumbria, at 2,930 feet (893 m) and other principal peaks in the North Pennines are Great Dun Fell 2,782 ft (848 m), Mickle Fell 2,585 ft (788 m), and Burnhope Seat 2,451 ft (747 m). Principal peaks in the Yorkshire Dales include Whernside 2,415 ft (736 m), Ingleborough 2,372 ft (723 m), High Seat 2,328 ft (710 m), Wild Boar Fell 2,324 ft (708 m) and Pen-y-ghent 2,274 ft (693 m). Principal peaks in

10092-423: The next vertebral body fits. Even these patterns are only generalisations, however, and there may be variation in form of the vertebrae along the length of the spine even within a single species. Some unusual variations include the saddle-shaped sockets between the cervical vertebrae of birds and the presence of a narrow hollow canal running down the centre of the vertebral bodies of geckos and tuataras , containing

10208-430: The north–south Pennine Way (268 miles/431 km) at Crowden-in-Longdendale . Considerable areas of the Pennines are protected as UK national parks and Areas of Outstanding Natural Beauty (AONBs). Areas of Outstanding Natural Beauty are afforded much the same protection as national parks. The national parks within the Pennines are the Peak District National Park (1) and the Yorkshire Dales National Park (7) with

10324-405: The number of cervical vertebrae can range from a single vertebra in amphibians to as many as 25 in swans or 76 in the extinct plesiosaur Elasmosaurus . The dorsal vertebrae range from the bottom of the neck to the top of the pelvis . Dorsal vertebrae attached to the ribs are called thoracic vertebrae, while those without ribs are called lumbar vertebrae. The sacral vertebrae are those in

10440-446: The opposite, possessing anterior convexity and posterior concavity. They are found in salamanders, and in some non-avian dinosaurs. Heterocoelous vertebrae have saddle -shaped articular surfaces. This type of configuration is seen in turtles that retract their necks, and birds, because it permits extensive lateral and vertical flexion motion without stretching the nerve cord too extensively or wringing it about its long axis. In horses,

10556-423: The pelvic region, and range from one in amphibians, to two in most birds and modern reptiles, or up to three to five in mammals. When multiple sacral vertebrae are fused into a single structure, it is called the sacrum. The synsacrum is a similar fused structure found in birds that is composed of the sacral, lumbar, and some of the thoracic and caudal vertebra, as well as the pelvic girdle . Caudal vertebrae compose

10672-418: The posterior part of one somite fuses to the anterior part of the consecutive somite during a process termed resegmentation. Disruption of the somitogenesis process in humans results in diseases such as congenital scoliosis. So far, the human homologues of three genes associated to the mouse segmentation clock, (MESP2, DLL3 and LFNG), have been shown to be mutated in cases of congenital scoliosis, suggesting that

10788-417: The posterior surface by the articular processes in the cervical and thoracic regions and by the transverse processes in the lumbar region. In the thoracic region, the sides of the bodies of the vertebrae are marked in the back by the facets for articulation with the heads of the ribs. More posteriorly are the intervertebral foramina, formed by the juxtaposition of the vertebral notches, oval in shape, smallest in

10904-400: The range and in northwest England the lack of natural aquifers is compensated for by reservoirs. Water has carved out limestone landscapes in the North Pennines, Yorkshire Dales and Peak District, with gorges and caves present in the Yorkshire Dales and Peak District. In some areas, precipitation has contributed to poor soils, resulting in part in moorland landscapes that characterize much of

11020-546: The range. In other areas where the soil has not been degraded, it has resulted in lush vegetation. For the purpose of growing plants, the Pennines are in hardiness zones 7 and 8, as defined by the USDA . Zone 8 is common throughout most of the UK, and zone 7 is the UK's coldest hardiness zone. The Pennines, Scottish Highlands , Southern Uplands and Snowdonia are the only areas of the UK in zone 7. The Pennines have been carved from

11136-542: The sacrovertebral articulation, and ends at the point of the coccyx ; its concavity is directed downward and forward as a kyphotic curve. The thoracic and sacral kyphotic curves are termed primary curves, because they are present in the fetus . The cervical and lumbar curves are compensatory , or secondary , and are developed after birth. The cervical curve forms when the infant is able to hold up its head (at three or four months) and sit upright (at nine months). The lumbar curve forms later from twelve to eighteen months, when

11252-488: The shales and sandstones of the Millstone Grit form high hills occupied by moorland covered with bracken , peat , heather and coarse grasses; the higher ground is uncultivable and barely fit for pasture. The Pennines contained Bronze Age settlements, and evidence remains of Neolithic settlement including many stone circles and henges , such as Long Meg and Her Daughters . The uplands were controlled by

11368-401: The spine is established during embryogenesis when somites are rhythmically added to the posterior of the embryo. Somite formation begins around the third week when the embryo begins gastrulation and continues until all somites are formed. Their number varies between species: there are 42 to 44 somites in the human embryo and around 52 in the chick embryo. The somites are spheres, formed from

11484-446: The spinous process of the seventh thoracic vertebra. This curve is known as a kyphotic curve. The lumbar curve is more marked in the female than in the male; it begins at the middle of the last thoracic vertebra, and ends at the sacrovertebral angle. It is convex anteriorly, the convexity of the lower three vertebrae being much greater than that of the upper two. This curve is described as a lordotic curve. The sacral curve begins at

11600-647: The surrounding foothills and lowlands. The Pennines contain the highest village in the United Kingdom, Flash , at 1,519 feet (463 m), near the southern end of the range in Staffordshire . The main economic activities in the Pennines include sheep farming , quarrying , finance and tourism . In the Peak District , tourism is the major local employment for park residents (24%), with manufacturing industries (19%) and quarrying (12%) also being important while 12% are employed in agriculture. Limestone

11716-416: The tail, and the final few can be fused into the pygostyle in birds, or into the coccygeal or tail bone in chimpanzees (and humans ). The vertebrae of lobe-finned fishes consist of three discrete bony elements. The vertebral arch surrounds the spinal cord, and is of broadly similar form to that found in most other vertebrates. Just beneath the arch lies a small plate-like pleurocentrum, which protects

11832-415: The tail. The general structure of human vertebrae is fairly typical of that found in other mammals , reptiles , and birds ( amniotes ). The shape of the vertebral body does, however, vary somewhat between different groups. In humans and other mammals, it typically has flat upper and lower surfaces, while in reptiles the anterior surface commonly has a concave socket into which the expanded convex face of

11948-488: The topsoil gets waterlogged in winter and spring. Here tree suppression combined with the heavier rainfall results in blanket bog up to 7 ft (2 m) thick. The erosion of peat still exposes stumps of ancient trees. "In digging it away they frequently find vast fir trees, perfectly sound, and some oaks ..." Limestone areas of the Pennines in the White Peak , Yorkshire Dales and Upper Teesdale have been designated as nature reserves or Important Plant Areas by

12064-518: The topsoil is so acidic, pH 2 to 4, that it can grow only bracken , heather , sphagnum , and coarse grasses such as cottongrass , purple moor grass and heath rush . As the Ice age glacial sheets retreated c. 11,500 BC trees returned and archaeological palynology can identify their species. The first trees to settle were willow, birch and juniper, followed later by alder and pine. By 6500 BC temperatures were warmer and woodlands covered 90% of

12180-419: The total number of vertebrae ranges from 32 to 35. In about 10% of people, both the total number of pre-sacral vertebrae and the number of vertebrae in individual parts of the spine can vary. The most frequent deviations are: 11 (rarely 13) thoracic vertebrae, 4 or 6 lumbar vertebrae, 3 or 5 coccygeal vertebrae (rarely up to 7). There are numerous ligaments extending the length of the column, which include

12296-592: The tribal federation of the Brigantes , made up of small tribes who inhabited the area and cooperated on defence and external affairs. They evolved an early form of kingdom. During Roman times , the Brigantes were dominated by the Romans who exploited the Pennines for their natural resources including the wild animals found there. The Pennines were an obstacle for Anglo-Saxon expansion westwards, although it appears

12412-404: The upland and lowland landscapes. The landscape is higher and more mountainous in the Yorkshire Dales and North Pennines. The Yorkshire Dales are characterised by valleys, moorlands and fells while the North Pennines consist of plateaus, moorlands, fells, edges and valleys, with most of the higher peaks in the west. Rising less than 3,000 feet (900 m), the Pennines are fells , with most of

12528-463: The upper surface of the notochord , and below that, a larger arch-shaped intercentrum to protect the lower border. Both of these structures are embedded within a single cylindrical mass of cartilage. A similar arrangement was found in the primitive Labyrinthodonts , but in the evolutionary line that led to reptiles (and hence, also to mammals and birds), the intercentrum became partially or wholly replaced by an enlarged pleurocentrum, which in turn became

12644-760: The valley of the River Trent . The Border Moors and Cheviot Hills , which lie beyond the Tyne Gap, are included in some definitions of the range. The range is divided into two by the Aire Gap , a wide pass formed by the valleys of the rivers Aire and Ribble . There are several spurs off the main Pennine range east into Greater Manchester and Lancashire , comprising the Rossendale Fells , West Pennine Moors , and Bowland Fells . The Howgill Fells and Orton Fells in Cumbria are also sometimes considered to be Pennine spurs. The Pennines are an important water catchment area, with numerous reservoirs in

12760-449: The vertebrae consist of two cartilaginous tubes. The upper tube is formed from the vertebral arches, but also includes additional cartilaginous structures filling in the gaps between the vertebrae, and so enclosing the spinal cord in an essentially continuous sheath. The lower tube surrounds the notochord, and has a complex structure, often including multiple layers of calcification . Lampreys have vertebral arches, but nothing resembling

12876-409: The vertebral bodies found in all higher vertebrates . Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region. Hagfishes lack a true vertebral column, and are therefore not properly considered vertebrates, but a few tiny neural arches are present in

12992-501: The vertebral body does, however, vary somewhat between different groups of living species. Individual vertebrae are named according to their corresponding body region ( neck , thorax , abdomen , pelvis or tail ). In clinical medicine , features on vertebrae (particularly the spinous process ) can be used as surface landmarks to guide medical procedures such as lumbar punctures and spinal anesthesia . There are also many different spinal diseases in humans that can affect both

13108-475: The vertebral column presents in the median line the spinous processes. In the cervical region (with the exception of the second and seventh vertebrae), these are short, horizontal, and bifid. In the upper part of the thoracic region they are directed obliquely downward; in the middle they are almost vertical, and in the lower part they are nearly horizontal. In the lumbar region they are nearly horizontal. The spinous processes are separated by considerable intervals in

13224-644: Was Common Brittonic . During the Early Middle Ages , the Cumbric language developed. Little evidence of Cumbric remains, so it is difficult to ascertain whether or not it was distinct from Old Welsh . The extent of the region in which Cumbric was spoken is also unknown. During Anglo-Saxon times the area was settled by Anglian peoples of Mercia and Northumbria , rather than the Saxon people of Southern England . Celtic speech remained in most areas of

13340-621: Was closed in 1981. The London and North Western Railway acquired the Huddersfield and Manchester Railway in 1847 and built a single-line tunnel parallel to the canal tunnel at Standedge with a length of 3 miles, 57 yards (4803 m). Today rail services along the Huddersfield line between Huddersfield and Victoria and Piccadilly stations in Manchester are operated by TransPennine Express and Northern . Between 1869 and 1876

13456-506: Was unified the Pennines were incorporated. The mix of Celtic, Anglo-Saxon and Viking heritage resembled much of the rest of northern England and its culture developed alongside its lowland neighbours in northwest and northeast England. The Pennines were not a distinct political polity , but were divided between neighbouring counties in northeast and northwest England; a major part was in the West Riding of Yorkshire . The Pennine region
