Intervertebral Disc

March 3, 2010 By 3 Comments


Intervertebral discs is fibrocartilage that lies  between  two adjacent vertebrae in the spine. Each disc forms a cartilaginous joint to allow slight movement of the vertebrae, and acts as a ligament to hold the vertebrae together.

Discs consist of an outer annulus fibrosus, which surrounds the inner nucleus pulposus.

There  are a total of twenty-three discs in the spine. They are identified by specifying the particular vertebrae they separate. For example, the disc between the fifth and sixth cervical vertabrae is designated as C5-6 disc.
