The nucleus pulposus is a soft, elastic, gelatinous core located in the center of the intervertebral disc. It acts as a shock absorber and helps distribute pressure evenly across the disc. The annulus fibrosus is a tough outer ring of fibrocartilage that surrounds the nucleus pulposus. The annulus fibrosus provides structural support and helps resist compressive forces on the disc.
