Intervertebral Disc Anatomy Function Degeneration Herniation 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 acts as a cushion, allowing the spine to bend and twist without damaging the vertebrae. Intervertebral discs are crucial components of the spinal column, sitting between the vertebrae. they are flat, round, and about a half inch thick, composed of two main parts: the nucleus pulposus and the annulus fibrosus. the nucleus pulposus, a jelly like center made partly of water, provides flexibility and strength to the disc. the annulus fibrosus surrounds […].
Intervertebral Discs Structure Function And Disorders Spine Info Functions. the intervertebral disc forms the fibrocartilaginous joint which allows slight movement of the vertebral column, and acts as a ligament to hold the vertebrae together. the discs act as fibrocartilaginous cushions, serving as the spine’s shock absorbing system. this cushions the effect of shock and stress produced when an individual. The intervertebral disc (ivd) is a shock absorbing structure with three main components: the inner nucleus pulposus, the outer annulus fibrosus and the cartilaginous endplates (ceps), which anchor the disc to the adjacent vertebrae. the healthy nucleus pulposus is a highly hydrated, gelatinous, proteoglycan rich tissue. Definition description. 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. The intervertebral disks along the spine provide motion and protection against mechanical loading. the 3 structural components, nucleus pulposus, annulus fibrosus, and cartilage endplate, function as a synergistic unit, though each has its own role. the cells within each of these components have distinct origins in development and morphology, producing specific extracellular matrix proteins.

The ivd is a tough tissue structure sandwiched between the vertebral bodies (fig. 1). it has three functions including: 1) acting as a ligament to hold the vertebrae of the spine together; 2) a shock absorber; and 3) a “pivot point” that allows the spine to bend, rotate, and twist. The intervertebral disc has two main parts: the tough outer layer known as the annulus fibrosus and the jelly like centre called the nucleus pulposus. together, they create a strong yet flexible cushion between your vertebrae, allowing your spine to move smoothly while providing support. inside the annulus fibrosus, special cells make tough.
