130-643: Nymphalis antiopa , known as the mourning cloak in North America and the Camberwell beauty in Britain , is a large butterfly native to Eurasia and North America. The immature form of this species is sometimes known as the spiny elm caterpillar . Other older names for this species include grand surprise and white petticoat . A powerful flier, this species is sometimes found in areas far from its usual range during migration. These butterflies have

The English monarchs, through inheritance of substantial territories in France and claims to the French crown, were also heavily involved in conflicts in France, most notably the Hundred Years' War , while the Kings of Scots were in an alliance with the French during this period. Early modern Britain saw religious conflict resulting from the Reformation and the introduction of Protestant state churches in each country. The English Reformation ushered in political, constitutional, social and cultural change in

The prevailing wind is from the southwest and bears frequent spells of mild and wet weather from the Atlantic Ocean, although the eastern parts are mostly sheltered from this wind. Since the majority of the rain falls over the western regions,
520-604: A welfare state was established, and a comprehensive, publicly funded healthcare system, the National Health Service , was created. The rise of nationalism in the colonies coincided with Britain's much-diminished economic position, so that a policy of decolonisation was unavoidable. Independence was granted to India and Pakistan in 1947. Over the next three decades, most colonies of the British Empire gained their independence, and many became members of

They are used in anatomy, surface anatomy, surgery, and radiology. Structures may be described as being at the level of a specific spinal vertebra , depending on the section of the vertebral column the structure is at. The position is often abbreviated. For example, structures at

The ventral side of the wings has gray striations, with the same pale-yellow edges. They are a part of the family Nymphalidae , called the brush-footed butterflies due to their hairy front legs. The species does not display any obvious sexual dimorphism . Mourning cloak butterflies display polygynous mating behavior, where an individual male will mate with multiple females throughout one breeding season. He will either use
910-448: A definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes . The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal . Additionally, for some animals such as invertebrates , some terms may not have any meaning at all; for example, an animal that

This means that male mourning cloak butterflies primarily lek , or display territorial behavior, in which they settle and defend desirable areas, such as those that either offer increased probability of females or those that provide ample amounts of good resources. The more desirable territories will be able to increase
1170-556: A few inches of a bright dress show below her mourning dress. The name originated from the discovery of two individuals at Coldharbour Lane in Camberwell in August 1748. Camberwell is in South London, about three miles south of London Bridge—in reporting this, the author Moses Harris named the species grand surprise or Camberwell beauty (Bretherton & Emmet, 1990). The mourning cloak butterflies are distributed broadly around
1300-554: A few minutes before returning to their natural healthy and lively behavior. Further defense mechanisms include loud clicks when the mourning cloak flies away from a predator. To protect themselves from the cold weather of their habitats, mourning cloaks will find areas under direct sunlight. This behavior, in conjunction with their darkly-colored wings, allow for maximum heat absorption. Newly hatched mourning cloak caterpillars can display selfish behavior, such as siblicide , by eating non-hatched eggs. The larvae also group together for

The specific epithet antiopa is thought to be derived from Antiope , a common name in Greek mythology . In several European countries with Germanic languages , other than Britain, the name for this butterfly literally translates to "mourning cloak", such as German "Trauermantel", Dutch "rouwmantel", Swedish "sorgmantel", Finnish "suruvaippa" and Norwegian "sørgekåpe". This suggests it

During this time, Canada , Australia and New Zealand were granted self-governing dominion status. At the turn of the century, Britain's industrial dominance became challenged by the German Empire and the United States . The Edwardian era saw social reform and home rule for Ireland become important domestic issues, while
1820-811: A portion of the North American population migrates southward. Experiments carried out in Germany by Hubert Roer in 1962-68, documented a long-distance (one way) migration from Bonn to Greece (Chalkiditi). Upon hatching, the caterpillars will begin to eat the leaves of the larval food-plant. A large number of food-plant plants was recorded, such as willow ( Salix nigra , Salix pentandra , Salix caprea , Salix aurita , Salix cinerea , Salix phylicifolia ), American elm , hackberry , hawthorn , wild rose , Betula species ( Betula verrucosa , Betula chinensis ), Alnus incana and poplar . The caterpillars live gregariously in communal silken nest on
1950-440: A process called ecdysis . The larvae experience a fifth skin shed to produce a fully grown caterpillar. The next stage in the mourning cloak's life cycle is to morph into a pupa and then cocoon in a process that encases the creature in a tan or gray chrysalis, which will hang from the stems of grass. This pupa stage allows for resting and further maturation. This metamorphosis takes approximately fifteen days. Following development as

However, its involvement in the First World War and the Second World War damaged Britain's economic power and a global wave of decolonisation led to the independence of most British colonies. The United Kingdom is a constitutional monarchy and parliamentary democracy . The UK has three distinct jurisdictions: England and Wales , Scotland , and Northern Ireland . Since 1999, Scotland, Wales and Northern Ireland have their own governments and parliaments which control various devolved matters. A developed country ,

Although the monarchy was restored , the Interregnum along with the Glorious Revolution of 1688 and the subsequent Bill of Rights 1689 in England and Claim of Right Act 1689 in Scotland ensured that, unlike much of
2470-414: A standard set of terms to communicate clearly the position of a structure. Standard anatomical and zoological terms of location have been developed, usually based on Latin and Greek words, to enable all biological and medical scientists, veterinarians , doctors and anatomists to precisely delineate and communicate information about animal bodies and their organs, even though the meaning of some of
2600-403: A state in which a part further away is abnormally placed towards (varus) or away from (valgus) the midline. The terms proximal (from Latin proximus 'nearest') and distal (from Latin distare 'to stand away from') are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively. Thus the upper arm in humans

Unfortunately, different authors use the terms in opposite senses. Some consider "distal" as further from a point of origin near the centre of the body and others as further from where the organ reaches the body's surface; or other points of origin may be envisaged. This terminology

They will break diapause once some, though not all, of the butterflies start to migrate through September and October. They then overwinter, and then restart their mating cycle throughout the spring, from April through June. Mourning cloaks, like all other butterflies, undergo complete metamorphosis. Egg →Larva (L1 ... L5) → Pupa → Adult. Before

Hugh Newman raised thousands for release at his 'farm' in Bexley , but none were seen the following spring. Specimens stored in his refrigerator for the winter, however, survived. In a book he said that Camberwell Beauty catches in England were suspiciously concentrated around London, Hull and Harwich , all these being ports in
3510-481: Is only the one specific nominal term 'Great Britain' which invariably excludes Northern Ireland". The BBC historically preferred to use "Britain" as shorthand only for Great Britain, though the present style guide does not take a position except that "Great Britain" excludes Northern Ireland. The adjective "British" is commonly used to refer to matters relating to the United Kingdom and is used in law to refer to United Kingdom citizenship and nationality . People of

Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or distal in relation to another point of reference. Thus the elbow is distal to

Most of the country consists of lowland terrain, with upland and mountainous terrain northwest of the Tees–Exe line which roughly divides
4030-402: Is rarely used in human anatomy, apart from embryology, and refers more to the front of the face than the superior aspect of the organism. Similarly, the term "caudal" is used more in embryology and only occasionally used in human anatomy. This is because the brain is situated at the superior part of the head whereas the nose is situated in the anterior part. Thus, the "rostrocaudal axis" refers to

The word England is occasionally used incorrectly to refer to the United Kingdom as a whole, a mistake principally made by people from outside the UK. The term "Britain" is used as a synonym for Great Britain , but also sometimes for the United Kingdom. Usage is mixed: the UK Government prefers to use the term "UK" rather than "Britain" or "British" on its website (except when referring to embassies), while acknowledging that both terms refer to

To describe how close to the head of an animal something is, three distinct terms are used: For example, in horses , the eyes are caudal to the nose and rostral to the back of the head. These terms are generally preferred in veterinary medicine and not used as often in human medicine. In humans, "cranial" and "cephalic" are used to refer to the skull, with "cranial" being used more commonly. The term "rostral"
4810-434: Is to the midline, or the medial plane. Lateral (from Latin lateralis 'to the side') describes something to the sides of an animal, as in "left lateral" and "right lateral". Medial (from Latin medius 'middle') describes structures close to the midline, or closer to the midline than another structure. For example, in a human, the arms are lateral to the torso .

9750-620: The United Kingdom. The 1928 Equal Franchise Act gave women electoral equality with men in national elections. Strikes in the mid-1920s culminated in the General Strike of 1926 . Britain had still not recovered from the effects of the First World War when the Great Depression (1929–1932) led to considerable unemployment and hardship in the old industrial areas, as well as political and social unrest with rising membership in communist and socialist parties. A coalition government
9880-640: The United States to establish the IMF , World Bank and NATO . The war left the UK severely weakened and financially dependent on the Marshall Plan , but it was spared the total war that devastated eastern Europe. In the immediate post-war years, the Labour government under Clement Attlee initiated a radical programme of reforms, which significantly impacted British society in the following decades . Major industries and public utilities were nationalised ,
10010-573: The acquisition and settlement of overseas colonies , particularly in North America and the Caribbean. Though previous attempts at uniting the two kingdoms within Great Britain in 1606, 1667, and 1689 had proved unsuccessful, the attempt initiated in 1705 led to the Treaty of Union of 1706 being agreed and ratified by both parliaments. On 1 May 1707, the Kingdom of Great Britain was formed,
10140-412: The beginning of their mating season, when female mourning cloaks will find a host plant and begin to lay their eggs. Adult mourning cloak butterflies can first be seen in late spring through early summer. They then aestivate for the summer, where they will enter into a "dormant" state similar to that of hibernation. In concordance with this is the mourning cloak butterflies' exhibition of diapause , which
10270-400: The body in a standing position with arms at the side and palms facing forward, with thumbs out and to the sides. Many anatomical terms can be combined, either to indicate a position in two axes simultaneously or to indicate the direction of a movement relative to the body. For example, "anterolateral" indicates a position that is both anterior and lateral to the body axis (such as the bulk of
10400-570: The body. These terms refer to the distance of a structure from the surface. Deep (from Old English ) describes something further away from the surface of the organism. For example, the external oblique muscle of the abdomen is deep to the skin. "Deep" is one of the few anatomical terms of location derived from Old English rather than Latin – the anglicised Latin term would have been "profound" (from Latin profundus 'due to depth'). Superficial (from Latin superficies 'surface') describes something near
10530-410: The butterflies' major predators include praying mantises, assassin bugs, dragon flies, and vertebrate predators such as birds, reptiles, amphibians, and mammals. An anti-predation mechanism the mourning cloaks have employed as adult butterflies is camouflage. To do this, the butterflies fold their wings back when attached to trees as their folded wings will provide camouflage against the dark backdrop of
10660-403: The chrysalis is the emergence of an adult mourning cloak butterfly. Studies show that the mourning cloaks use endocrine mechanisms similar to other lepidopterans to regulate female specific protein synthesis, oogenesis , and male and female reproductive gland development. Juvenile hormone (JH) is involved in the regulation of oogenesis and development of the male and female reproductive glands in
10790-417: The closeness to the midline of the dental arch. Terms used to describe structures include "buccal" (from Latin bucca 'cheek') and "palatal" (from Latin palatum 'palate') referring to structures close to the cheek and hard palate respectively. Several anatomical terms are particular to the hands and feet. Additional terms may be used to avoid confusion when describing
10920-610: The color change was due to hormonal changes in response to varying temperatures. Mourning cloak butterflies are protected by law in Switzerland and Austria, though they generally have an increasing trend regarding population density in Finland. They also assume "safe" status in the Czech Republic. In general, the mourning cloak butterflies find areas that have experienced fire breaks to be more inviting, presumably because
11050-736: The decades-long process of European integration , the UK was a founding member of the Western European Union , established with the London and Paris Conferences in 1954. In 1960 the UK was one of the seven founding members of the European Free Trade Association (EFTA), but in 1973 it left to join the European Communities (EC). In a 1975 referendum 67% voted to stay in it. When the EC became
11180-443: The duration of their development, preventing some predation by numbers. The larvae and pupae can also respond to disturbances by twitching simultaneously – this may be performed as a defense mechanism. Mourning cloak butterflies are not known to be significant pollinators, since their primary food source is sap of deciduous trees rather than flowering plants. However, they still can occasionally act as pollinators. On occasions,
11310-483: The eastern parts are the driest. Atlantic currents, warmed by the Gulf Stream , bring mild winters, especially in the west where winters are wet and even more so over high ground. Summers are warmest in the southeast of England and coolest in the north. Heavy snowfall can occur in winter and early spring on high ground, and occasionally settles to great depth away from the hills. The average total annual sunshine in
11440-421: The end of words: Superior (from Latin super 'above') describes what is above something and inferior (from Latin inferus 'below') describes what is below it. For example, in the anatomical position , the most superior part of the human body is the head and the most inferior is the feet. As a second example, in humans, the neck is superior to the chest but inferior to
11570-399: The environment affects certain butterfly phenotypic characteristics. Scientists hypothesized that traumatic heat or cold shocks "during a critical period of its development can cause profound changes". The first experiments occurred in the 1890s. The mourning cloaks were temperature shocked at specific times in their development, which led to differences in pupae color. It was later learned that
11700-546: The establishment of the British Empire . Over the course of the 17th century, the role of the British monarchy was reduced, particularly as a result of the English Civil War . In 1707, the Kingdom of England and the Kingdom of Scotland united under the Treaty of Union to create the Kingdom of Great Britain . The Acts of Union 1800 incorporated the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland in 1801. Most of Ireland seceded from
11830-576: The fire breaks increase the amount of open space and clearings available to the butterflies, which is a more ideal habitat for these butterflies to live in. Subspecies include: United Kingdom The United Kingdom of Great Britain and Northern Ireland , commonly known as the United Kingdom ( UK ) or Britain , is a country in Northwestern Europe , off the coast of the continental mainland . It comprises England , Scotland , Wales , and Northern Ireland . The UK includes
11960-594: The first year, Britain and its Empire continued the war against Germany. Churchill engaged industry, scientists and engineers to support the government and the military in the prosecution of the war effort. In 1940, the Royal Air Force defeated the German Luftwaffe in the Battle of Britain . Urban areas suffered heavy bombing during the Blitz . The Grand Alliance of Britain, the United States and
12090-587: The formal control it exerted over its own colonies, British dominance of much of world trade meant that it effectively controlled the economies of regions such as East Asia and Latin America . Throughout the Victorian era , political attitudes favoured free trade and laissez-faire policies. Beginning with the Great Reform Act in 1832, Parliament gradually widened the voting franchise , with
12220-762: The global hegemon and adopted the role of global policeman. From 1853 to 1856, Britain took part in the Crimean War , allied with the Ottoman Empire against Tsarist Russia , participating in the naval battles of the Baltic Sea known as the Åland War in the Gulf of Bothnia and the Gulf of Finland , among others. Following the Indian Rebellion in 1857 , the British government led by Lord Palmerston assumed direct rule over India . Alongside
12350-429: The gregarious mourning cloak larvae will completely defoliate ornamental trees, in nurseries, plantations, and parks. Some areas that this damage has been documented has been Oregon and Canada. The young willows and poplars could be completely defoliated due to the caterpillars, though mature trees tend not to be affected. Mourning cloak butterflies have been a part of some epigenetics experiments testing to determine if
12480-417: The hand') is commonly used to describe the front of the hand, and dorsal is the back of the hand. For example, the top of a dog 's paw is its dorsal surface; the underside, either the palmar (on the forelimb) or the plantar (on the hindlimb) surface. The palmar fascia is palmar to the tendons of muscles which flex the fingers, and the dorsal venous arch is so named because it is on the dorsal side of
12610-417: The host-plant, until they disperse prior to pupation. Adult mourning cloaks primarily feed on sap, ripe and fallen fruits and sugary exudate from aphids, very rarely seen nectaring on flowers. The mourning cloak butterfly faces many predators throughout its development. The mourning cloak's eggs can be eaten by predators such as beetles, true bugs, ants, beetle larvae, wasps, assassin bugs, and mites. Some of
12740-773: The island of Great Britain , the north-eastern part of the island of Ireland , and most of the smaller islands within the British Isles , making up a total area of 94,354 square miles (244,376 km ). Northern Ireland shares a land border with the Republic of Ireland ; otherwise, the United Kingdom is surrounded by the Atlantic Ocean , the North Sea , the English Channel , the Celtic Sea , and
12870-403: The kingdoms of England, Scotland and Ireland were united in a personal union when James VI, King of Scots , inherited the crowns of England and Ireland and moved his court from Edinburgh to London; each country nevertheless remained a separate political entity and retained its separate political, legal, and religious institutions. In the mid-17th century, all three kingdoms were involved in
13000-621: The larval food-plant, encircling the stem. Later in season, when the leaves appear, females also lay the eggs on the upper surface. The spiny caterpillars are striking in appearance, with black bodies and a line of eight reddish-orange dots running down the back (aposematic, warning coloration). The prolegs are dark red. The body is covered with short hairs and black spines and white dots. The fully grown mourning cloak caterpillars attain two inches in length. Mourning cloak pupae are on average 0.8 inches (2.0 cm) in length, though they can reach over 1.1 inches (2.8 cm) in length. They tend to be
13130-408: The last retreat of the ice around 11,500 years ago. By the end of the region's prehistoric period , the population is thought to have belonged largely to a culture termed Insular Celtic , comprising Brittonic Britain and Gaelic Ireland . The Roman conquest , beginning in 43 AD, and the 400-year rule of southern Britain , was followed by an invasion by Germanic Anglo-Saxon settlers, reducing
13260-473: The leaves bud-out, Mourning cloaks are known to lay their eggs as ring clusters around the terminal twigs on host plants. The host plant selection is vital because it provides the food source for the young caterpillars. Females are known to have multiple broods, typically up to two to three. The newly hatched caterpillars will group together until they shed their skin—termed an instar for each shedding. This shedding event occurs four times throughout development in
13390-409: The legal and political systems of many of its former colonies , and British culture remains globally influential, particularly in language , literature , music and sport . English is the world's most widely spoken language and the third-most spoken native language . The Acts of Union 1707 declared that the Kingdom of England and Kingdom of Scotland were "United into One Kingdom by
13520-512: The legs. Temporal has a similar meaning to lateral but is restricted to the head. The terms "left" and "right" are sometimes used, or their Latin alternatives ( Latin : dexter , lit. 'right'; Latin : sinister , lit. 'left'). However, it is preferred to use more precise terms where possible. Terms derived from lateral include: Varus (from Latin 'bow-legged') and valgus (from Latin 'knock-kneed' ) are terms used to describe
13650-448: The level of the fourth cervical vertebra may be abbreviated as "C4", at the level of the fourth thoracic vertebra "T4", and at the level of the third lumbar vertebra "L3". Because the sacrum and coccyx are fused, they are not often used to provide the location. References may also take origin from superficial anatomy , made to landmarks that are on the skin or visible underneath. For example, structures may be described relative to
13780-530: The local cultures. Subsequent medieval English kings completed the conquest of Wales and tried unsuccessfully to annex Scotland . Asserting its independence in the 1320 Declaration of Arbroath , Scotland maintained its independence thereafter, albeit in near-constant conflict with England . In 1215 the Magna Carta was the first document to state that no government was above the law, that citizens have rights protecting them and that they were entitled to
13910-401: The main body, terms to describe position need to refer to an animal when it is in its standard anatomical position . This means descriptions as if the organism is in its standard anatomical position, even when the organism in question has appendages in another position. This helps avoid confusion in terminology when referring to the same organism in different postures. In humans, this refers to
14040-618: The major part of the British Isles archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and some smaller surrounding islands. It lies between the North Atlantic Ocean and the North Sea with the southeast coast coming within 22 miles (35 km) of the coast of northern France, from which it is separated by the English Channel . The Royal Greenwich Observatory in London
14170-410: The male-male competition for mating, this strategy offers males an ideal location in order to maximize success in territorial protection, and thus mating. Despite the fact that butterflies, particularly the mourning cloak butterflies, have an affinity for perches on high objects, they are not known to display any hilltopping behavior, where male butterflies fly up to perch on hill summits. Spring marks
14300-497: The males' chances of reproductive success. Thus, lekking maximizes the males' ability to attract the most female butterflies, either by being in a prime location to view them or to have a location that females would want to visit. Locations of choice typically include sunny perches near ravines, wood margins, parks, gardens, lakes, ponds, around stream edges, or canyons in which males can perch and defend for multiple days. These locations can be more than an area of 300 square meters. Given
14430-674: The mid-1920s, most of the British population could listen to BBC radio programmes. Experimental television broadcasts began in 1929 and the first scheduled BBC Television Service commenced in 1936. The rise of Irish nationalism , and disputes within Ireland over the terms of Irish Home Rule , led eventually to the partition of the island in 1921. A period of conflict in what is now Northern Ireland occurred from June 1920 until June 1922. The Irish Free State became independent, initially with Dominion status in 1922, and unambiguously independent in 1931 . Northern Ireland remained part of
14560-429: The mourning cloak butterfly. The adult butterflies hibernate during the winter months. Typical locations of overwintering include tree cavities and on the ground underneath loose tree bark (covered by snow). They often emerge from hibernation before the snow has completely melted, making it one of the first butterflies to take wing in the spring. The mourning cloak is a non-migratory species but some sources suggest that
14690-456: The mouth and teeth. This is because although teeth may be aligned with their main axes within the jaw, some different relationships require special terminology as well; for example, teeth also can be rotated, and in such contexts terms like "anterior" or "lateral" become ambiguous. For example, the terms "distal" and "proximal" are also redefined to mean the distance away or close to the dental arch , and "medial" and "lateral" are used to refer to
14820-456: The northern hemisphere. They are commonly found throughout all of North America and northern Eurasia. Three subspecies of mourning cloak butterflies are found throughout North America: northern Nymphalis antiopa hyperborea Seitz, 1913; eastern N. a. lintnerii Fitch, 1857; southwestern N. a. thomsoni Butler, 1887. They can usually be found in hardwood forests, though they have been found in virtually all habitats. They may also be found as far as
14950-613: The northern part of South America, though they are typically not seen as frequently in southern states such as Florida, Louisiana, or Texas. They are occasionally seen in the more temperate places in Asia, and a few have even been seen in Japan. However, the mourning cloaks tend to be found predominantly in cold, mountainous areas. Migrants arrive in Great Britain most years during summer and autumn, but numbers are usually very low. There
15080-463: The only part of the island of Ireland within the United Kingdom, the name was changed in 1927 to the "United Kingdom of Great Britain and Northern Ireland". Although the United Kingdom is a sovereign country, England, Scotland, Wales and Northern Ireland are also widely referred to as countries . The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom. Some statistical summaries, such as those for
15210-400: The outer surface of the organism. For example, in skin , the epidermis is superficial to the subcutis . These two terms, used in anatomy and embryology , describe something at the back ( dorsal ) or front/belly ( ventral ) of an organism. The dorsal (from Latin dorsum 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about
15340-402: The outside of the left or right side of the body toward the inside) or "mediolateral"(from the inside of that side of the body toward the outside. The same logic is applied to all planes of the body and, thus top-to-bottom or bottom-to-top X-ray projections are known as "superoinferior" and "inferosuperior," respectively. However, within the diagnostic imaging industry, for this particular example,
15470-504: The rest of Europe, royal absolutism would not prevail, and a professed Catholic could never accede to the throne. The British constitution would develop on the basis of constitutional monarchy and the parliamentary system . With the founding of the Royal Society in 1660, science was greatly encouraged. During this period, particularly in England, the development of naval power and the interest in voyages of discovery led to
15600-587: The result of the Acts of Union 1707 between the Kingdom of England and Kingdom of Scotland . In the 18th century, cabinet government developed under Robert Walpole , in practice the first prime minister (1721–1742). A series of Jacobite uprisings sought to remove the Protestant House of Hanover from the throne and restore the Catholic House of Stuart . The Jacobites were finally defeated at
15730-442: The skull, the dorsal side is the top. The ventral (from Latin venter 'belly') surface refers to the front, or lower side, of an organism. For example, in a fish, the pectoral fins are dorsal to the anal fin , but ventral to the dorsal fin . The terms are used in other contexts; for example dorsal and ventral gun turrets on a bomber aircraft. Specific terms exist to describe how close or far something
15860-460: The surfaces of the hand and what is the "anterior" or "posterior" surface. The term "anterior", while anatomically correct, can be confusing when describing the palm of the hand; Similarly is "posterior", used to describe the back of the hand and arm. This confusion can arise because the forearm can pronate and supinate and flip the location of the hand. For improved clarity, the directional term palmar (from Latin palma 'palm of
15990-429: The terms "cranial" (towards the head) and "caudal" (towards the tail, or, downwards, away from the head) are known interchangeable alternatives to the previous two projection terms. Combined terms were once generally hyphenated, but the modern tendency is to omit the hyphen. Anatomical terms describe structures with relation to four main anatomical planes : The axes of the body are lines drawn about which an organism
16120-404: The terms often is context-sensitive. Much of this information has been standardised in internationally agreed vocabularies for humans ( Terminologia Anatomica ) and animals ( Nomina Anatomica Veterinaria ). Different terms are used for groups of creatures with different body layouts, such as bipeds (creatures that stand on two feet, such as humans) and quadrupeds . The reasoning is that
16250-468: The timber trade with Scandinavia , and theorized that they had hibernated in stacks of timber which was then shipped to England, and had not traveled naturally. Mourning cloak eggs are amber-yellow or pale olive-green when first laid. Upon further development, the coloration of the eggs will change, becoming lilac-pink, and darkening to almost black, as they mature prior to hatching. The eggs are generally 0.7 by 0.9 mm in size. Laid on terminal shoots of
16380-403: The trees. An additional anti-predation tactic used by the mourning cloaks is to join together with other butterflies in a perch and fly menacingly towards their attackers—most often birds or other butterflies. Mourning cloaks also play dead by closing their wings tightly together and tucking their legs up against their body for protection and holding completely still. They will maintain this for
16510-436: The twelve NUTS 1 regions , refer to Scotland, Wales and Northern Ireland as "regions". Northern Ireland is also referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice often revealing one's political preferences". The term "Great Britain" conventionally refers to the island of Great Britain, or politically to England, Scotland and Wales in combination. It
16640-623: Was chosen as the defining point of the Prime Meridian at the International Meridian Conference in 1884. The United Kingdom lies between latitudes 49° and 61° N , and longitudes 9° W and 2° E . Northern Ireland shares a 224-mile (360 km) land boundary with the Republic of Ireland. The coastline of Great Britain is 11,073 miles (17,820 km) long, though measurements can vary greatly due to
16770-470: Was formed in 1931. Nonetheless, "Britain was a very wealthy country, formidable in arms, ruthless in pursuit of its interests and sitting at the heart of a global production system." After Nazi Germany invaded Poland in 1939, Britain entered the Second World War . Winston Churchill became prime minister and head of a coalition government in 1940. Despite the defeat of its European allies in
16900-432: Was the first country in the world to use an approved COVID-19 vaccine , developing its own vaccine through a collaboration between Oxford University and AstraZeneca , which allowed the UK's vaccine rollout to be among the fastest in the world. The total area of the United Kingdom is approximately 94,354 square miles (244,376 km ), with a land area of 93,723 square miles (242,741 km ). The country occupies
