spine

The spine, also called the backbone, is a central structure made up of 33 interconnected bones called vertebrae. It runs from the base of your skull down to your pelvis, providing support for your upper body and enabling movement. The spine also protects the spinal cord, a vital bundle of nerves that transmits signals between your brain and the rest of your body. It has natural curves, which help absorb shocks and maintain balance. The spine's flexibility and strength are essential for everyday activities like walking, lifting, and bending.
