The anulus fibrosus is the tough, outer layer of intervertebral discs in the spine, composed of several layers of fibrocartilage. It encases the softer nucleus pulposus, providing structural support and resilience to the disc. This structure helps absorb shock and maintain stability between the vertebrae during movement. Damage or degeneration of the anulus fibrosus can lead to conditions such as herniated discs.
