Intervertebral Disc
in·ter·ver·te·bral disk
\ˌin-tər-ˈvər-tə-brəl\ disk\
noun
There are a number of these discs in the human body, located between adjacent vertebrae in the spine. Every disc forms a fibrocartilaginous joint that allows the vertebrae to move slightly, and it also acts as a ligament to ensure the vertebrae are held together. We also need intervertebral discs because they act as shock absorbers.
