Understanding Spinal Anatomy: Intervertebral Discs. Between each vertebral body is a cushion called an intervertebral disc. Each disc absorbs the stress and shock the body incurs during movement and prevents the vertebrae from grinding against one another. The intervertebral discs are the largest structures in the body without a vascular supply. By means of osmosis, each disc absorbs needed nutrients.
The disc (shock absorber between two vertebrae) is either bulging or herniated and is pressing upon the fornt surface of the spinal cord. Depending upon the sympoms you are having, this could be a surgical problem.
