40-449: Mahā Bandha ("the great lock") combines all the other three bandhas, namely: In Ashtanga Vinyasa Yoga , these three Bandhas are considered to be one of the three key principles of yoga practice. Mūla bandha is a primary bandha in traditional yoga . The earliest textual mention of mūla bandha is in the 12th century Shaiva Natha text Gorakṣaśataka which defines it as a yogic technique to achieve mastery of breath and to awaken

80-423: A corresponding one on the xiphoid process, forms a notch for the cartilage of the seventh rib. These articular depressions are separated by a series of curved interarticular intervals, which diminish in length from above downward, and correspond to the intercostal spaces. Most of the cartilages belonging to the true ribs , articulate with the sternum at the lines of junction of its primitive component segments. This

120-432: A front and back surface. It is flat on the front, directed upward and forward, and marked by three transverse ridges which cross the bone opposite the third, fourth, and fifth articular depressions. The pectoralis major attaches to it on either side. At the junction of the third and fourth parts of the body is occasionally seen an orifice, the sternal foramen, of varying size and form. The posterior surface, slightly concave,

160-418: A high BMI (obese or grossly overweight) may present with excess tissue that makes access to traditional marrow biopsy sites such as the pelvis difficult. A somewhat rare congenital disorder of the sternum sometimes referred to as an anatomical variation is a sternal foramen, a single round hole in the sternum that is present from birth and usually is off-centered to the right or left, commonly forming in

200-432: A radical surgery, usually to surgically treat a malignancy, either with or without a mediastinal lymphadenectomy ( Current Procedural Terminology codes # 21632 and # 21630, respectively). A bifid sternum is an extremely rare congenital abnormality caused by the fusion failure of the sternum. This condition results in sternal cleft which can be observed at birth without any symptom. The sternum, in vertebrate anatomy,

240-480: Is a flat bone that lies in the middle front part of the rib cage . It is endochondral in origin. It probably first evolved in early tetrapods as an extension of the pectoral girdle ; it is not found in fish . In amphibians and reptiles , it is typically a shield-shaped structure, often composed entirely of cartilage . It is absent in both turtles and snakes . In birds , it is a relatively large bone and typically bears an enormous projecting keel to which

280-492: Is a long flat bone located in the central part of the chest . It connects to the ribs via cartilage and forms the front of the rib cage , thus helping to protect the heart , lungs , and major blood vessels from injury. Shaped roughly like a necktie , it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process . The word sternum originates from Ancient Greek στέρνον ( stérnon ) 'chest'. The sternum

320-437: Is a narrow, flat bone , forming the middle portion of the front of the chest . The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs . The inner surface of the sternum is also the attachment of the sternopericardial ligaments . Its top is also connected to the sternocleidomastoid muscle . The sternum consists of three main parts, listed from

360-432: Is also marked by three transverse lines, less distinct, however, than those in front; from its lower part, on either side, the transversus thoracis takes origin. The sternal angle is located at the point where the body joins the manubrium. The sternal angle can be felt at the point where the sternum projects farthest forward. However, in some people the sternal angle is concave or rounded. During physical examinations,

400-704: Is performed by extending the neck and elevating the sternum (breastbone) before dropping the head so that the chin may rest on the chest. Meanwhile, the tongue pushes up against the palate in the mouth.

440-442: Is rare and usually caused by severe trauma. It may also result from minor trauma where there is a precondition of arthritis. The breastbone is sometimes cut open (a median sternotomy ) to gain access to the thoracic contents when performing cardiothoracic surgery . Surgical fixation of sternotomy is achieved through the use of either wire cerclage or a plate and screw technique. The incidence of sternotomy complications falls within

480-424: Is well seen in some other vertebrates, where the parts of the bone remain separated for longer. The upper border is oval and articulates with the manubrium, at the sternal angle. The lower border is narrow, and articulates with the xiphoid process . Located at the inferior end of the sternum, is the pointed xiphoid process . Improperly performed chest compressions during cardiopulmonary resuscitation can cause

520-426: The chest of both sexes . The Greek physician Hippocrates used στέρνον to refer to the chest , and στῆθος to the breastbone . The Greek physician Galen was the first to use στέρνον in the present meaning of breastbone . The sternum as the solid bony part of the chest can be related to Ancient Greek στερεός/στερρός , ( stereόs/sterrόs ) , meaning firm or solid . The English term breastbone

560-416: The 2nd, 3rd, and 4th segments of the breastbone body. Congenital sternal foramina can often be mistaken for bullet holes. They are usually without symptoms but can be problematic if acupuncture in the area is intended. Fractures of the sternum are rather uncommon. They may result from trauma, such as when a driver's chest is forced into the steering column of a car in a car accident . A fracture of

600-419: The body from the anus to the navel is contracted and lifted up and towards the spine". This is qualified in that the actual muscle contracted is not the sphincter muscle nor the muscle which cessates urination, but the muscle equidistant between the two . Maehle defines it as "root lock" and further specifies that: The root referred to here is the root of the spine, the pelvic floor or, more precisely,

640-400: The body of the sternum, the clavicles and the cartilages of the first 1.5 pairs of ribs . The inferior border, oval and rough, is covered with a thin layer of cartilage for articulation with the body. The lateral borders are each marked above by a depression for the first costal cartilage , and below by a small facet, which, with a similar facet on the upper angle of the body, forms a notch for

680-406: The bony tissue is generally only superficial, the central portion of the intervening cartilage remaining unossified. The body of the sternum is formed by the fusion of four segments called sternebrae . In 2.5–13.5% of the population, a foramen known as sternal foramen may be presented at the lower third of the sternal body. In extremely rare cases, multiple foramina may be observed. Fusion of

720-476: The breath and then releasing the abdomen after a pause. The process is repeated many times before letting the air into the lungs, resuming normal breath. Jalandhara bandha ( Sanskrit : जालंधर बंध , IAST : Jālandhara bandha) is the chin bandha described and employed in Hatha Yoga . Jālandhara bandha comes from Sanskrit : जाल Jāla , web or net and ( Sanskrit : धर ) dhara , "holding". This bandha

760-455: The central channel, called sushumna , which is the subtle equivalent of the spine. Mūla Bandha is a primary Bandha in traditional yoga . Iyengar likens the functionality of the Bandha and especially Mūla Bandha to "safety-valves which should be kept shut during the practice of kumbhakas". He specifies the energetic prāṇas of Vāyus engaged through Mūla Bandha as: "...Apāna Vāyu (the prāṇa in

800-401: The centre of the pelvic floor, the perineum . The perineum is the muscular body between the anus and the genitals. By slightly contracting the pubo-coccygeal (PC) muscle , which goes from the pubic bone to the tail bone (coccyx), we create an energetic seal that locks prana into the body and so prevents it from leaking out at the base of the spine. Mula Bandha is said to move prana into

840-405: The first year after birth; and in the xiphoid process, between the fifth and eighteenth years. The centers make their appearance at the upper parts of the segments, and proceed gradually downward. To these may be added the occasional existence of two small episternal centers, which make their appearance one on either side of the jugular notch ; they are probably vestiges of the episternal bone of

880-542: The flame, fanned by the wind, rises high. As a result, fire and apāna reach prāṇa , which is hot by nature. The overheated prāṇa creates a blaze in the body, which heats the sleeping Kuṇḍalinī and wakes her up. Like a snake struck by a stick, she hisses and straightens herself. As if entering a snake-hole, she enters the Brahmā naḍi . Therefore, yogis should maintain the regular practice of mūla bandha . Gorakṣaśataka Iyengar defines Mūla Bandha as "A posture where

920-428: The flight muscles are attached. Only in mammals does the sternum take on the elongated, segmented form seen in humans. In arthropods, a sternum is the ventral part of a segment of thorax or abdomen . English sternum is a translation of Ancient Greek στέρνον , sternon . The Greek writer Homer used the term στέρνον to refer to the male chest , and the term στῆθος , stithos to refer to

960-404: The goddess Kuṇḍalinī . Mula Bandha ( Sanskrit : मूल बंध) is from Mūla , meaning variously root, base, beginning, foundation, origin or cause. Gorakṣhaśataka defines mūla bandha as: [The yogi] forces the downward-moving apāna breath to move upwards by means of contraction. Yogis call this mūla bandha , "the root lock." When apāna has turned upwards and reached the orb of fire, then

1000-414: The irregular union of which explains the rare occurrence of the sternal foramen [Fig. 7], or of the vertical fissure which occasionally intersects this part of the bone constituting the malformation known as fissura sterni; these conditions are further explained by the manner in which the cartilaginous sternum is formed. More rarely still the upper end of the sternum may be divided by a fissure . Union of

1040-429: The lower abdomen), whose course is downwards, is made to flow up to unite with Prāna Vāyu, which has its seat within the region of the chest." He cautions that "Mūla Bandha should be attempted first in antara kumbhaka (retention after inhalation). The region of the lower abdomen between the navel and the anus is contracted towards the spine and pulled up to the diaphragm. He further states that "While practicing Mūla Bandha,

1080-406: The lower sternum. Its inferior attachment is the internal surface of costal cartilages two through six and works to depress the ribs. The sternum develops from two cartilaginous bars one on the left and one on the right, connected with the cartilages of the ribs on each side. These two bars fuse together along the middle to form the cartilaginous sternum which is ossified from six centers: one for

1120-458: The male than in the female. The manubrium ( Latin for 'handle') is the broad upper part of the sternum. It has a quadrangular shape, narrowing from the top, which gives it four borders. The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles . On either side of this notch are the right and left clavicular notches . The manubrium joins with

1160-428: The manubriosternal joint also occurs in around 5% of the population. Small ossicles known as episternal ossicles may also be present posterior to the superior end of the manubrium. Another variant called suprasternal tubercle is formed when the episternal ossicles fuse with the manubrium. Because the sternum contains bone marrow , it is sometimes used as a site for bone marrow biopsy . In particular, patients with

1200-404: The manubrium, four for the body, and one for the xiphoid process . The ossification centers appear in the intervals between the articular depressions for the costal cartilages , in the following order: in the manubrium and first piece of the body, during the sixth month of fetal life; in the second and third pieces of the body, during the seventh month of fetal life; in its fourth piece, during

1240-447: The monotremata and lizards. Occasionally some of the segments are formed from more than one center, the number and position of which vary [Fig. 6]. Thus, the first piece may have two, three, or even six centers. When two are present, they are generally situated one above the other, the upper being the larger; the second piece has seldom more than one; the third, fourth, and fifth pieces are often formed from two centers placed laterally,

1280-443: The narrow range of 0.5% to 5%. Nevertheless, these complications can have severe consequences, including increased mortality rates, the need for reoperation, and a mortality rate as high as 40%. Such complications often entail issues like dehiscence and sternal non-union, primarily stemming from lateral forces exerted during post-operative activities such as coughing and sneezing. The sternum can be totally removed (resected) as part of

1320-430: The reception of the costal cartilage of the second rib. Between the depression for the first costal cartilage and the demi-facet for the second is a narrow, curved edge, which slopes from above downward towards the middle. Also, the superior sternopericardial ligament attaches the pericardium to the posterior side of the manubrium. The body, or gladiolus, is the longest sternal part. It is flat and considered to have only

1360-401: The sternal angle is a useful landmark because the second rib attaches here. Each outer border, at its superior angle, has a small facet, which with a similar facet on the manubrium, forms a cavity for the cartilage of the second rib; below this are four angular depressions which receive the cartilages of the third, fourth, fifth, and sixth ribs. The inferior angle has a small facet, which, with

1400-516: The sternum is usually a comminuted fracture. The most common site of sternal fractures is at the sternal angle . Some studies reveal that repeated punches or continual beatings, sometimes called "breastbone punches", to the sternum area have also caused fractured sternums. Those are known to have occurred in contact sports such as hockey and football. Sternal fractures are frequently associated with underlying injuries such as pulmonary contusions , or bruised lung tissue. A manubriosternal dislocation

1440-422: The top five ribs join with the sternum at the sternocostal joints . The right and left clavicular notches articulate with the right and left clavicles, respectively. The costal cartilage of the second rib articulates with the sternum at the sternal angle making it easy to locate. The transversus thoracis muscle is innervated by one of the intercostal nerves and superiorly attaches at the posterior surface of

1480-415: The top: In its natural position, the sternum is angled obliquely, downward and forward. It is slightly convex in front and concave behind; broad above, shaped like a "T", becoming narrowed at the point where the manubrium joins the body, after which it again widens a little to below the middle of the body, and then narrows to its lower extremity. In adults the sternum is on average about 1.7 cm longer in

1520-425: The various centers of the body begins about puberty , and proceeds from below upward [Fig. 5]; by the age of 25 they are all united. The xiphoid process may become joined to the body before the age of thirty, but this occurs more frequently after forty; on the other hand, it sometimes remains ununited in old age. In advanced life the manubrium is occasionally joined to the body by bone. When this takes place, however,

1560-400: The xiphoid process to snap off, driving it into the liver which can cause a fatal hemorrhage. The sternum is composed of highly vascular tissue, covered by a thin layer of compact bone which is thickest in the manubrium between the articular facets for the clavicles . The inferior sternopericardial ligament attaches the pericardium to the posterior xiphoid process. The cartilages of

Uḍḍīyana bandha ( Sanskrit : उड्डीयन बन्ध), also called abdominal lock or upward lifting lock , is the abdominal bandha described and employed in hatha yoga , in particular in the nauli purification. It involves, after having exhaled all the air out, pulling the abdomen under the rib cage by taking a false inhale while holding
