Nucleus Pulposus

The nucleus pulposus is the soft, gel-like core inside each intervertebral disc in the spine. It acts as a shock absorber, enabling the spine to handle movements like bending, twisting, and absorbing impacts. Composed mainly of water and collagen, it helps distribute pressure evenly across the spine. As we age or after injury, the nucleus pulposus can lose some of its water content and elasticity, potentially leading to disc problems such as herniation, which may cause back pain or nerve issues. Overall, it plays a crucial role in spinal flexibility and load management.
