The structure of vertebral column


Vertebral column composes of 33 vertebra (spinal column bones) including 7 cervical, 12 thoracic, 5 lumbar and 5 fused sacrum and 4 fused coccyx. Its major function is to support the body and protect the spinal cord.

The 7 cervical vertebra are separated by fibrous tissue, i.e. intervertebral disc. This disc gives spine the flexibility to move and absorb shock during body movement.

The vertebrae encircles and protects your spinal cord. Nerves branching from the spinal cord pass through openings in the vertebrae to other parts of your body. This gives your body sensation and enables your body to perform different activity and motion.

Intervertebral disc degeneration
As intervertebral disc loses their water content because of disease or age, they lose their height and bring vertebrae closer together. The consequence is weakening of the shock absorption properties of the disc and a narrowing of the openings for the nerves in the sides of the spine. Additionally, a loss of intervertebral disc height may cause the formation of bone spurs, which can push against your spinal cord and/or nerves.

When a intervertebral disc ruptures in the cervical spine, it puts pressure on one or more nerve roots or on the spinal cord, causing pain and other symptoms in the neck and arms.
