Glossary of Terms

Vertebrae: the small bones that together form the backbone. Each has several projections for articulation and muscle attachment, and a hole through which the spinal cord passes.

Herniated Disc: A tear or weakness in the outer layer of one of the spinal discs (which serve as shock absorbers between the vertebrae) that allows the fluidic inner layer to leak into the spinal canal. This places pressure on the local nerves causing pain, discomfort and other complications.
