The backbone, also known as the vertebral column, is a rod-like structure composed of 33 vertebrae running from the neck to the hips. It provides essential support to the body, protects the spinal cord, and allows for flexibility and movement through cartilage discs between vertebrae. Additionally, the backbone supports the head and connects to the shoulder bones, ribs, and hipbone.
