Without our bones, we couldn't stand, walk, run, or even sit. Our bones provide support for our bodies and help form our shape. They protect our organs against injury and enable us to move. They're strong enough to support our entire weight, yet are very lightweight themselves. Some bones protect other parts of the body, as the skull protects the brain, and others work together to make body parts move, such as the arm and leg bones.
Joints occur where two bones meet.
They make the skeleton flexible - without them, movement would be impossible. Working together, bones, joints, and muscles enable us to do all the physical activities we do every day. For specific medical advice, diagnoses, and treatment, consult your doctor.
