The vertebral column, also known as the backbone or spine, is part of the axial skeleton. The vertebral column is the defining characteristic of a vertebrate in which the notochord (a flexible rod of uniform composition) found in all chordates has been replaced by a segmented series of bone: vertebrae separated by intervertebral discs.

The vertebrae are classified as irregular bones. Due to their function in protecting the spinal cord while allowing a flexibility of movement, vertebrae have a distinctive shape that prohibits easy grouping within a regular type.


Every vertebra has a body, which consists of a large anterior middle portion called the centrum (plural centra) and a posterior vertebral arch, also called a neural arch. The body is composed of cancellous bone, which is the spongy type of osseous tissue, whose micro-anatomy has been specifically studied within the pedicle bones.

The vertebral column is a series of approximately 33 bones called vertebrae, which are separated by intervertebral discs.. The column can be divided into five different regions, with each region characterised by a different vertebral structure.. In this article, we shall look at the anatomy of the vertebral column – its function, structure and clinical significance.


There is a part of the body, the vertebral foramen, where the spinal cord passes through, and a number of processes exist. These processes are elongated, bony protrusions that help in articulation with muscles and other bones. Cervical vertebrae. These make up the first section of the vertebral column and comprise 7 bones – C1 to C7.


In a spinal fusion, two or more vertebrae (bones) are fused together with healthy bone (usually using bone graft harvested from your bone or from a bone bank) and locked in place (often with hardware like metal rods, plates, screws etc.). This fusion is a permanent solution used to correct alignment or a degenerative problem.


Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.
