Spinal Column: An Integral Part of the Human Body The bones in the spine are called vertebrae (ver-ta-bray). The column starts at the base of the skull and continues to the pelvis. Alternate layers of bone (vertebrae) and cartilage (car-til-ledge, the intervertebral discs) stack vertically one on top of the other in the spinal column.

Seventh cervical vertebra In humans, cervical vertebrae are the smallest of the true vertebrae, and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which passes the vertebral artery.The remainder of this article focuses upon human anatomy.horacic vertebrae in all mammalian species are defined as those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae. Further caudally follow the lumbar vertebrae, which also belong to the trunk, but do not carry ribs.

Each vertebra has three main functional components: the vertebral body for load-bearing, the vertebral arch to protect the spinal cord, and transverse processes for ligament attachment. The spinal column consists of seven cervical, twelve thoracic, and five lumbar vertebrae in addition to five fused vertebrae of the sacral region and four fused vertebrae forming the coccyx. The vertebrae in each region have unique features that help them perform their main functions.

Intervertebral â definition and relationship to spine conditions Intervertebral — definition and relationship to spine conditions. The term intervertebral means “between the vertebrae” and it is usually used to describe the spinal discs that are layered between each vertebra, acting as shock absorbers. The spine is basically a stack of bones called the vertebrae that are connected by facet joints and cushioned by the intervertebral discs. These parts work together to protect the spinal cord and support and move the upper body.

- suffix -bra. The notion is of the spine as the hinge of the body. The bones of the pelvis are ankylosed together, and to a large though variable number of vertebrae. Its flesh is delicate and firm, and with the exception of the vertebrae, has no long bones. Between the neck and the complex and solid sacral bone there are sixteen vertebrae, and there are twelve pairs of ribs, as in Man. Then it fell, shearing through the scales and flesh and vertebrae.

Seventh cervical vertebra In vertebrates, cervical vertebrae (singular: vertebra) are the vertebrae of the neck, immediately below the skull. Thoracic vertebrae in all mammalian species are those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae. Further caudally follow the lumbar vertebrae, which also belong to the trunk, but do not carry ribs. In reptiles, all trunk vertebrae carry ribs and are called dorsal vertebrae.

It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord.There about 50,000 species of animals that have a vertebral column.The human vertebral column is one of the most-studied examples.t is commonly called the spine, or simply backbone. The articulating vertebrae are grouped into their regions; there are seven cervical vertebrae of the neck (C1 to C7); twelve thoracic vertebrae of the thorax (T1 to T12); and five lumbar vertebrae of the lower back above the pelvis (L1 to L5).
