I WONDER - How Does The Spine Move?

The video tutorial explains the anatomy and function of the vertebral discs and facet joints in the spine. It describes how the rubbery discs between vertebrae act as cushions, allowing the spine to bend and twist while absorbing shock. The structure of these discs includes a tough outer layer and a jelly-like center. Additionally, the video covers how facet joints connect vertebrae, contributing to the spine's flexibility and movement.
