Costotransverse Ligament
A costotransverse ligament is a short fibrous band that connects a rib with the transverse process of vertebra. They are some of the ligaments that surround the costovertebral joint. Types There are three types of costotransverse ligaments in the human body: costo-transverse ligament (connects the posterior surface of the neck of the rib with the transverse process of the corresponding vertebrae); lateral costotransverse ligament (connects the non-articular part of the rib with the tip of transverse process); and superior costotransverse ligament (connects the upper border of the neck of the rib to the inferior border of the transverse process of the vertebrae above). In addition, some sources also list the inferior costotransverse ligament, and the posterior costotransverse ligament in this grouping. Functions * Support and prevent dislocation of ribs and limit the costotransverse joint The costotransverse joint is the joint formed between the facet of the tubercle of the rib an ...

Transverse Process
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the vertebral column, backbone), and on the other with phylogenetic differences among the vertebrate taxon, taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ligament
A ligament is the fibrous connective tissue that connects bones to other bones. It is also known as ''articular ligament'', ''articular larua'', ''fibrous ligament'', or ''true ligament''. Other ligaments in the body include the: * Peritoneal ligament: a fold of peritoneum or other membranes. * Fetal remnant ligament: the remnants of a fetal tubular structure. * Periodontal ligament: a group of fibers that attach the cementum of teeth to the surrounding alveolar bone. Ligaments are similar to tendons and fasciae as they are all made of connective tissue. The differences among them are in the connections that they make: ligaments connect one bone to another bone, tendons connect muscle to bone, and fasciae connect muscles to other muscles. These are all found in the skeletal system of the human body. Ligaments cannot usually be regenerated naturally; however, there are periodontal ligament stem cells located near the periodontal ligament which are involved in the adult regener ...

Lateral Costotransverse Ligament
The lateral costotransverse ligament is a short, thick, though ligament of the costotransverse joint The costotransverse joint is the joint formed between the facet of the tubercle of the rib and the adjacent transverse process of a thoracic vertebra. The costotransverse joint is a plane type of synovial joint which, under physiological conditio ... which strengthens the joint posteriorly. It connects (the rough, non-articular portion of) the tubercle of a rib, and the transverse process of the corresponding vertebra. It extends obliquely: at the upper ribs, it is directed inferior-ward from the ribs; at the lower ribs, it is directed superior-ward from the ribs. It is more oblique and shorter at the upper ribs.

Superior Costotransverse Ligament
A superior costotransverse ligament is a strong fibrous band that arises from the neck of a rib to the transverse process of the vertebra The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic ... above. It comprises two sets of fibers. The anterior set passes obliquely superiorly and laterally from the sharp crest on the superior border of the neck of each rib to the anterior surface of the transverse process of the vertebra immediately superior to it. The posterior set passes superiorly and medially from the crest on the superior border of the neck of the rib to the inferior border of the transverse process of the vertebra immediately superior to it. The ligament may be absent for the first rib.Ibrahim AF, Darwish HH, The costotransverse ligaments in human: a detailed anatomical study, Cl ...

Costotransverse Joint
The costotransverse joint is the joint formed between the facet of the tubercle of the rib and the adjacent transverse process of a thoracic vertebra. The costotransverse joint is a plane type of synovial joint which, under physiological conditions, allows only gliding movement. This costotransverse joint is present in all but the eleventh and twelfth ribs. The first ten ribs have two joints in close proximity posteriorly; the costovertebral joints and the costotransverse joints. This arrangement restrains the motion of the ribs allowing them to work in a parallel fashion during breathing. If a typical rib had only one joint posteriorly the resultant swivel action would allow a rib to be non-parallel with respect to the neighboring ribs making for a very inefficient breathing. The intercostal nerves innervate the costotransverse joints. Therefore, therapeutic medial branch blocks are ineffectual. The ligaments of the joint are: * Articular capsule * Costotransverse ligament A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorax (human Anatomy)
The thorax or chest is a part of the anatomy of humans, mammals, and other tetrapod animals located between the neck and the abdomen. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the creature's body, each of which is in turn composed of multiple segments. The human thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain. Etymology The word thorax comes from the Greek θώραξ ''thorax'' "breastplate, cuirass, corslet" via la, thorax. Plural: ''thoraces'' or ''thoraxes''. Human thorax Structure In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
