Vertebra, Vertebrae (Plural) Definition Vertebra, Vertebrae (Plural) Definition. Vertebrae are the 33 individual, interlocking bones that form the spinal column. 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.

- Most vertebrates have a spinal column made of bones called vertebrae (see SPINE). But some, such as the shark, do not have a bony spinal column.

Cervical Vertebrae Definition Cervical Vertebrae Definition. The cervical vertebrae are the seven cylindrical bones, or vertebral bodies (C1-C7), that provide support and structure for the cervical spine. Cervical Spine Anatomy Video. The vertebral body is the large portion of the bone that lies anterior (in front of) the spinal cord.The vertebrae get smaller as they near the base of the skull and only the top two segments allow for rotation in the neck.The top cervical segment, called the atlas, is a ring that does not have a vertebral body.he atlas is attached to the second vertebral body (the axis), which acts as a post that the first vertebral ring rotates around. The segments in the cervical spine contain openings in each vertebral body for arteries to carry blood to the brain(vertebral foramen).
