Inside the spinal column of a human, there are 24 bones referred to as vertebrae. Between each vertebra bone is circular-shaped disc. These discs, separated into five distinct sections,rotate or move around as your body moves. If a basketball player jumps and shoot the ball, the discs will turn inside the spinal column. This allows the player to twist in the air. Connecting all these bones and dise is tissue called ligaments. These ligaments are just like an elastic band,stretching and moving as you do.when a person falls or land on the ground very hard, the vertebrae,these three parts function as a joint allowing our body to bend or twist.
