The nucleus pulposus (NP) and the anulus fibrosus (AF) are the two main components of the intervertebral discs. At low deformation rates, in young and healthy adults, the NP reacts like an inviscid and incompressible fluid. Its internal pressure varies depending on the external forces acting on it. The AF surrounds the NP and, together with the vertebral endplates, they form a pressurized vessel.
