Bones provide structure and support to allow the body to stand and move without collapsing. Joints connect bones and allow different ranges of motion, from little movement to more flexible joints like those in the thigh. Ligaments connect bones to other bones and provide stability, while vertebrae make up the backbone and its connections. The thigh bone and inner ear stirrup bone are examples of how bones work with joints and ligaments to enable movement.
