Physiology_Of_Bones

Physiology Of Bones Bones are hard substances that form the framework, give shape, support, and protect the vital organs of the human body. Bones are classified easiest by shape. There are the long bones, short bones, flat bones, irregular, and the sesamoid. Long bones typically make up the limbs. They consist of a central, usually hollow, tubular region, and the diaphysis, which is linked to the epiphysis by a metaphysis. Near the ends of the shaft the marrow cavity has a tendency to be broader and it is occupied with trabecular bone, arranged along lines of force which has a skeletal function in its own right and sustains the marrow. Short bones are found in the wrist and ankle, carpals and tarsals and have no shaft in view of the fact that they do not grow significantly in size during growth. They tend to be cuboidal in shape, and have a cancellous bone in the center and a hard outer shell of compact bone. Flat bones are found in the cranium or the scapula and are sandwiches of spongy bone amid two layers of compact bone and are usually curved.
