Quick Answer. According to the New York University Langone Medical Center, intervertebral discs are made up of fibrocartilage tissue, which has two layers. While the inner portion resembles jelly, the outermost part has strong and fibrous layers. About 90 percent of this tissue is water.
Annulus Fibrosus and Nucleus Pulposus. Intervertebral discs are composed of an annulus fibrosus and a nucleus pulposus. The annulus fibrosus is a strong radial tireâlike structure made up of lamellae; concentric sheets of collagen fibers connected to the vertebral end plates.The sheets are orientated at various angles.he annulus fibrosus encloses the nucleus pulposus. Although both the annulus fibrosus and nucleus pulposus are composed of water, collagen, and proteoglycans (PGs), the amount of fluid (water and PGs) is greatest in the nucleus pulposus. PG molecules are important because they attract and retain water.
