Document Summary

Bones provide structural support and serve as a framework for the entire body. Bones also protect many delicate tissues and organs from injury and trauma. The rib cage protects the heart and lungs the vertebrae enclose the spinal cord the cranial bones enclose and protect the brain the pelvis cradles some digestive, urinary, and reproductive organs. The bones of the body serve as lever arms and the muscles provide the force; together they produce limb and total body movement. The direction and magnitude of the forces generated by the skeletal muscles can be altered by bones. Potential movements range from powerful contractions needed for running and jumping to delicate, precise movements required to remove a splinter from the finger. Tissues in the middle of some bones (sternum, ilium) serve as the location for the production of blood cells. Blood cells are produced in a connective tissue called red bone marrow, which is located in some spongy bone.
