What is the anatomy of the disc of the spine (intervertebral disc)?

The disc is an important structure that rests between the bony building blocks of the spine (vertebrae). The disc in the spine is sometimes referred to as the intervertebral disc. Intervertebral discs help provide flexibility to our spine. They also lessen the effect of impact on our spine by cushioning the bony vertebrae. The disc is designed somewhat like a jelly donut. The disc has a stronger outer layer (the annulus) that is rather like a radial tire, and an inner gel (the nucleus) that acts as a sort of shock absorber or cushion between the bones of the spine.
