Intervertebral discs are soft, cushion-like structures located between the vertebrae in the spine. They act as shock absorbers, allowing for flexibility and movement while preventing the bones from grinding against each other. 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. Over time, they can degenerate or become damaged, leading to conditions such as herniated discs or degenerative disc disease. Proper care, including exercise and good posture, can help maintain their function and overall spinal health.
