What is a disk located in your back?

A disk located in your back refers to an intervertebral disc, which is a gel-like cushion situated between the vertebrae in the spinal column. These discs serve as shock absorbers, providing flexibility and support for the spine while allowing for movement. Each disc consists of a tough outer layer called the annulus fibrosus and a soft inner core known as the nucleus pulposus. They play a crucial role in maintaining spinal health and mobility.
