The CVA is an anatomic concept of the relationship of the 12th rib to the transverse processes of the lumbar vertebrae. [1] There is one CVA on each side of the spine. [2] The lateral part of the CVA is formed by the lower border of the 12th rib, and the medial part of the CVA is formed by the transverse processes of the lumbar vertebrae. [1]
The lumbar vertebrae are located between the thoracic vertebrae and pelvis. They form the lower part of the back in humans, and the tail end of the back in quadrupeds. In humans, there are five lumbar vertebrae. The term is used to describe the anatomy of humans and quadrupeds, such as horses, pigs, or cattle.
The transverse process of a lumbar vertebra is also sometimes called the costal [9] [10] or costiform process [11] because it corresponds to a rudimentary rib (costa) which, as opposed to the thorax, is not developed in the lumbar region.
The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.

For instance, the S1–S5 vertebrae of a horse will fuse, the S1–S3 of a dog will fuse, and four pelvic vertebrae of a rat will fuse between the lumbar and the caudal vertebrae of its tail. [ 3 ] The Stegosaurus dinosaur had a greatly enlarged neural canal in the sacrum, characterized as a " posterior brain case ".
The vertebral canal is enclosed anteriorly by the vertebral bodies, intervertebral discs, and the posterior longitudinal ligament; it is enclosed posteriorly by the vertebral laminae and the ligamenta flava; laterally, it is incompletely enclosed by the pedicles with the interval between two adjacent pedicles on either side creating an intervertebral foramen (allowing the passage of the spinal ...
A costal facet is a site of connection between a rib and a vertebra. The costal facets are located on the vertebrae that the rib articulates with. They are the superior costal facet, the inferior costal facet, and the transverse costal facet. [1] Rib 1 only articulates with a transverse costal facet.
