| The cushioning function of intervertebral discs. Shown are a normal disc left and an abnormal disc right, whose nucleus has hardened to reduce its cushioning ability. The nucleus is the gelatinous substance inside the cartilaginous annulus that defines the disc`s borders. Discs harden and lose cushioning as a result of age and/or injury. |
