Description
The human intervertebral disc (IVD) is a complex and dynamic structure that functions to provide spinal stability, mobility and flexibility. It comprises three main compartments: 1) a water-rich central compartment called the nucleus pulposus (NP), which is enveloped by 2) the annulus fibrosus (AF) and sandwiched between 3) two cartilaginous endplates (EP) from which the IVD gains its nutrition and provides a means to get rid of metabolic waste.
