Intervertebral disks

Intervertebral disks are an integral part of the human anatomy, specifically the spinal column. They are circular pads of fibrocartilage that are situated between the individual bones or vertebrae of the spine. These disks serve as shock absorbers, preventing the vertebrae from rubbing against each other and allowing for flexibility of the spine.

Structure

The intervertebral disks are composed of two parts: the annulus fibrosus and the nucleus pulposus. The annulus fibrosus is the tough, flexible outer ring of the disk, which is made up of several layers of fibrocartilage. The nucleus pulposus is the soft, jelly-like center of the disk, which serves to distribute pressure evenly across the disk.

Function

The primary function of the intervertebral disks is to act as shock absorbers for the spine. They allow for flexibility and movement of the spine, while also maintaining its structural integrity. The disks also serve to protect the spinal cord and the nerves that branch out from it.

Conditions

There are several medical conditions that can affect the intervertebral disks. These include disk herniation, disk degeneration, and spinal stenosis. These conditions can cause pain, numbness, and other symptoms, and may require treatment such as physical therapy, medication, or in some cases, surgery.

Treatment

Treatment for conditions affecting the intervertebral disks depends on the severity of the condition and the symptoms experienced by the patient. Non-surgical treatments include physical therapy, pain medication, and lifestyle changes such as weight loss and exercise. In severe cases, surgery may be required to remove or repair the affected disk.
