Cartilage and Bone Connective Tissue long bone : i.e. . femur, tibia, humerus short bone : knee caps, wrist bones, spongy compact covering flat bone : scull cap, sternum, ribs irregular bone : vertebrae, temple long bone features diaphysis : main, long staff portion epiphysis : proximal and distal ends metaphysis : area between, growing part of the bone. usually in children. still present in adults, but no longer growing. medullary cavity : inside of diaphysis, filled with yellow bone marrow. periosteum : membrane on surface of bone except where there is articulating cartilage. spongy (cancellous) bone : contains red bone marrow and made up of trabeculae. weight is much less, but able to support more. trabeculae : "little beams" that form a network, each contains lamellae and
