The science of the interaction of bone and muscle is called biomechanics?. The science of bones is called osteology?

Bones are generally tubular in structure, and the hollow space in the middle is filled with marrow?. The marrow is where [blood cell]?s are produced and thus critically important to healthy blood. At the ends are connections to other bones at joint?s which are lubricated and sometimes padded by softer tissue called cartilige?. The science of the interaction of bone and muscle is called biomechanics?. The science of bones is called osteology?. Some illnesses afflict human bones, for example osteoporosis and cancer. The joints can be affected by arthritus.
