Intervertebral Disc: Definition, Function & Disease The discs have a tough outer covering of cartilage that provides support (the annulus fibrosus) and a soft, jellylike center that provides the cushioning (the nucleus pulposus). The intervertebral discs have the following functions: They provide cushioning for the vertebrae and reduce the stress caused by impact. By keeping the vertebrae separated from each other, they act as a type of shock absorber for the spine.

The Know-It-All's Guide to Life As the human body ages, the intervertebral discs degenerate (break down), which leads to degenerative disc disease in some individuals. The changes that occur, due to aging, include: 1  Loss of fluid-the intervertebral discs of a healthy young adult consist mainly of fluid, up to 90%.

L5 (5th Lumbar Vertebra) Intervertebral disks made of strong, rubbery fibrocartilage lie between the bodies of each of the lumbar vertebrae and the sacrum. The intervertebral disks provide support, shock absorption, and flexibility to the lower back.

Damage to discs between vertebrae causes compression of spinal nerve roots Sections. The spine is composed of many bones called vertebrae, which are separated by tough pads (called intervertebral discs) intended to reduce shock and friction. When these discs degenerate due to age or injury, they can rupture, allowing the gelatinous material within to seep into the spaces between vertebrae.

What is an Intervertebral Disc? An intervertebral disc, or discus intervertebralis, is a structure consisting of fibrocartilage located between the vertebrae, the bones of the vertebral column, or spine.The intervertebral discs serve to hold the vertebrae together, cushion the spine, and allow for spinal movement.n intervertebral disc, or discus intervertebralis, is a structure consisting of fibrocartilage located between the vertebrae, the bones of the vertebral column, or spine.

Intervertebral disc overview Along with the facet joints, these discs enable basic spinal movement like bending, flexing and twisting. There are two parts that make up an intervertebral disc: the nucleus pulposus, or inner layer, and the annulus fibrosis, or outer layer. The nucleus pulposus is gel-like fluid that acts as a shock absorber.

- 1 Intervertebral disc disease (IVDD) is a condition in which a disc develops a problem and the material inside escapes into the spinal column, ultimately causing pain, nerve damage, and even paralysis. There are two types of IVDD: Hansen Type I, which involves the acute, explosive herniation of a disc, and Hansen Type II, which is a gradual, progressive protrusion of disc material.

Spinal Discs Spinal discs also act as ligaments that hold the vertebrae of the spine together and as cartilaginous joints that allow for slight mobility in the spine. There are a total of twenty-three vertebral discs in the spinal column.

- The spinal column is comprised of the vertebrae (the bone structures in the neck and back), the intervertebral discs and various ligaments and muscles. The vertebrae are responsible for lending the neck and back structure and serve as shields for the spinal cord.

Anterior Lumbar Fusion with Cages The intervertebral discs are the cushions between each pair of vertebrae. The fusion cages help separate the vertebral bodies, taking pressure off the spinal nerves where they travel from the spinal canal through openings called the neural foramen.

Disc desiccation Disc desiccation is an extremely common degenerative change of intervertebral discs. The incidence climbs with age, and to a large degree a gradual desiccation is a 'normal' part of disc aging. It results from replacement of the hydrophilic glycosaminoglycans within the nucleus polposus with fibrocartilage.isc desiccation is an extremely common degenerative change of intervertebral discs.

Intervertebral disk Intervertebral disk. An intervertebral disk acts as shock absorber between each of the vertebrae in the spinal column by keeping the vertebrae separated when there is impact from activity. They also serve to protect the nerves that run down the middle of the spine and intervertebral disks.he disks are made of fibrocartilaginous material. The outside of the disk is made of a strong material called the annulus fibrosus. Inside this protective covering is a jelly-like substance known as mucoprotein gel. This interior is known as the nucleus pulposus.

- Intervertebral disc degeneration is one of the most common mechanical causes of low back pain, and it occurs when the usually rubbery discs lose integrity as a normal process of aging. In a healthy back, intervertebral discs provide height and allow bending, flexion, and torsion of the lower back.

Treatment for slipped disc To understand what a slipped, or herniated, disc is, you have to understand how the intervertebral discs work in your spine. Intervertebral discs are natural shock absorbers between the stacked vertebrae. These discs have two main components, an outer fibro-elastic shell and an inner, gelatinous core.

Intervertebral disc It is the remnant of the notochord. There is one disc between each pair of vertebrae, except for the first cervical segment, the atlas. The atlas is a ring around the roughly cone-shaped extension of the axis (second cervical segment).
