An intervertebral disc is a fibrocartilaginous structure located between the vertebrae in the spinal column, acting as a cushion that absorbs shock and allows for mobility. These discs consist of a gel-like center called the nucleus pulposus, surrounded by a tough outer layer known as the annulus fibrosus. Their health and integrity are crucial for maintaining proper spinal function and can be a significant source of pain when damaged or degenerated, especially in conditions related to low back pain.
