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.
Overview: The intervertebral discs (the cushion in the space between the bones of the spine) have conditions and forces that can make them swell or rupture over time. This rupture leads to two types of damage to the spinal cord, compression and concussion. The extent of the damage and nerve cells loss is determined by:
