Nucleus pulposus
Nucleus pulposus
Definition
Each intervertebral disc is composed at its center, of a soft, pulpy, highly elastic substance, of a yellowish color, which projects considerably above the surrounding level when the disk is divided horizontally, the nucleus pulposus.
The pulpy substance presents no such arrangement, and consists of a fine fibrous matrix, containing angular cells united to form a reticular structure.
