Bones protect soft body organs for example, the fused bones of the skull provide a snug enclosure for the brain, the vertebrae surround the spinal cord, and the rib cage helps protect the vital organs of the thorax. Bones, the “steel girders” and “reinforced concrete” of the body, form the internal framework that supports the body and cradle its soft organs the bones of the legs act as pillars to support the body trunk when we stand, and the rib cage supports the thoracic wall.
