HELP WHAT ARE THE MUSCLES CALLED

Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight.Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
