Skeletal SystemWhat argon the five primary functions of the skeletal systemThere ar 206 swot up in the human body , change integrity into quartet categories Long tusks (eg , femur , short fig ups (eg , metacarpals , prosy gussy ups (eg sternum , and irregular swot (eg , vertebrae . The shape and building of a specific bone argon determined by its function and the forces exerted on it . swot up atomic modus operandi 18 constructed of cellular (trabecular or cortical ( crush ) bone interweave . Long bones atomic number 18 shaped manage rods or shafts with rounded ends . The shaft , cognise as the diapysis , is in the first place cortical bone . The ends of the long bones , called epiphyses , are in general cellular bone . The epiphyseal home base separates the epiphyses from the calamus and is the center for lon gitudinal growth in children . In the self-aggrandizing , it is calcified . The ends of long bones are covered at the joints by articular cartilage , which is tough , elastic avascular tissue . Long bones are designed for weight whole bearing and movement . Short bones consist of cancellous bone covered by a layer of jam bone (Hoyle , 2000 . Flat bones are importance sites for hematopoiesis and frequently provide vital organ protection . They are made of cancellous bone layered between bunch up bones . Irregular bones have unique shapes unite to their functions .

Generally , irregular bone structure is simil ar to that of plow bonesBone is composed o! f cells , protein intercellular substance , and mineral deposits . The cells are of leash basic types - osteoblasts , osteocytes , and osteoclasts . Osteoblasts function in bone formation by secreting bone matrix . The matrix , which consists of collagen and ground substances provides a poser in which inorganic mineral salts are deposited Osteocytes are fledged bone cells involved in bone-maintenance functions they are located in lacunae (small matrix units . Osteoclasts , located in shallow Howship s lacunae (small pits in bones , are multinuclear cells involved in destroying , resorbing , and remolding bone (Mays 2003ReferenceHoyle , Graham (2000 . comparative degree Physiology of the nauseous Control of Muscular Contraction .
