Each disc has a strong outer ring of fibers, called the annulus fibrosus, and a soft, jelly-like center, called the nucleus pulposus. The annulus is the strongest area of the disc and connects each vertebra together. The strong annular fibers contain the nucleus and distribute pressure evenly across the disc. The nucleus, or center of the disc, is hydrated and serves as the main shock absorber.
