The vertebral disc in the spine is an interesting and unique structure. Its primary purpose is to act as a shock absorber between adjacent vertebrae. Spinal discs also act as ligaments that hold the vertebrae of the spine together and as cartilaginous joints that allow for slight mobility in the spine.
There are a total of twenty-three vertebral discs in the spinal column. Specific problems with any of these discs may prompt different symptoms, including back pain, neck pain, and sciatica.
Spinal Disc Construction
Discs are actually composed of two parts: a tough outer portion and a soft inner core, and the configuration has been likened to that of a jelly doughnut.
The outer portion of the disc (annulus fibrosus) is the tough circular exterior composed of concentric sheets of collagen fibers (lamellae) that surround the inner core.
The inner core (nucleus pulposus) contains a loose network of fibers suspended in a mucoprotein gel.
