Bones provide support for our bodies and help form our shape. … Bones also protect the body’s organs. 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.
What type of bones support and protect?
Compact bone: Below the periosteum, compact bone is white, hard, and smooth. It provides structural support and protection.
Do bones support your body?
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.

How does the skeleton protect and support?
The skeleton supports the body against the pull of gravity. … The skeleton also protects the soft body parts. The fused bones of the cranium surround the brain to make it less vulnerable to injury. Vertebrae surround and protect the spinal cord and bones of the rib cage help protect the heart and lungs of the thorax.

Why are bones porous?

How do bones facilitate movement?
Bones also facilitate movement by serving as points of attachment for your muscles. While some bones only serve as a support for the muscles, others also transmit the forces produced when your muscles contract. From a mechanical point of view, bones act as levers and joints serve as fulcrums (Figure 5.2).
