The intervertebral disc is a flexible structure located between the vertebrae in the spine. It acts as a cushion, absorbing shock and allowing for movement. Each disc consists of a tough outer layer called the annulus fibrosus and a gel-like center known as the nucleus pulposus. These discs play a crucial role in maintaining spinal health and mobility. They help to distribute weight and pressure during activities like walking, bending, and lifting. Over time, discs can degenerate or become damaged, leading to conditions such as herniated discs or degenerative disc disease.
