Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae , to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine . So this part is the pulpy center of the intervertebral disc. It consists of three entities: the annulus pulposus (AP), nucleus pulposus (NP) and the vertebral end-plate (VEP). Lumbar Vertebrae Definition. Introduction.
