Intervertebral discs consist of a thick outer ring of fibrous cartilage called the anulus fibrosus (fibrous ring), which surrounds an inner gel-like center known as the nucleus pulposus (meaning “pulpy interior”). The nucleus pulposus is sandwiched inferiorly and superiorly by cartilage endplates.
An intervertebral disc is a structure located between adjacent vertebrae of the spine. It consists of a tough outer layer called the annulus fibrosus and a gel-like center called the nucleus pulposus.
The intervertebral disc (IVD) is important in the normal functioning of the spine. It is a cushion of fibrocartilage and the principal joint between two vertebrae in the spinal column. There are 23 discs in the human spine: 6 in the cervical region (neck), 12 in the thoracic region (middle back), and 5 in the lumbar region (lower back).  
central portion of the intervertebral disc that is surrounded by the annulus fibrosis. composed of type II collagen, water, and proteoglycans. ~88% water. hydrophilic matrix is responsible for height of the intervertebral disc. characterized by compressibility.
Intervertebral discs serve a number of vital functions in the realms of structural support and locomotion. Within the disc itself, the separate components serve different purposes. The NP serves to distribute hydraulic pressure throughout the intervertebral disc.
An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. 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.
An intervertebral disc is a mass of soft tissue located between the vertebrae of the spinal column. It acts as a shock absorber for the spine and allows independent movement of the vertebrae to increase flexibility in the spine.
Each intervertebral joint is a complex of three separate joints; an intervertebral disc joint (intervertebral symphysis) and two zygapophyseal (facet) joints. This article will describe the anatomy and function of the intervertebral joints.
Discover the anatomy, function, and structure of intervertebral discs. Learn how they contribute to spinal stability and shock absorption.
Each intervertebral disc is comprised of: peripheral annulus fibrosus. central nucleus pulposus. hyaline cartilage (vertebral side) and fibrocartilage (nucleus pulposus side) Above and below the intervertebral disc are the vertebral body endplates.
