How do intervertebral discs absorb shock in the spine?
I know that the discs between our vertebrae act as shock absorbers, but how do they actually do this? What are they made of, and how do their structures help cushion the spine during movement? Also, what happens when a disc herniates or degenerates-how does that affect the spine’s ability to absorb shock?

The discs have a tough outer layer (annulus fibrosus) and a gel-like center (nucleus pulposus). When you move or jump, the gel helps absorb and distribute the force, protecting the vertebrae.

As we age, the discs can lose water and become less flexible, which is why older people are more prone to back pain or herniated discs. Keeping your core strong can help support your spine.

A herniated disc happens when the gel center pushes out through a tear in the outer layer, which can press on nerves and cause pain or numbness.
