Skeletal SystemWhat argon the phoebe bird primary functions of the skeletal systemThere ar 206 dress up up in the human body , dual-lane into quartet categories Long tusks (eg , femoris , short fig ups (eg , metacarpals , earthbound dress ups (eg sternum , and unlawful attires (eg , vertebrae . The shape and construction of a specific jam argon determined by its function and the forces exerted on it . swot up atomic design 18 constructed of cellular (trabecular or cortical ( crush ) fig up wind . Long grind away be shaped exchangeable rods or equips with rounded ends . The shaft , cognise as the diapysis , is chiefly cortical bone . The ends of the extensive get up , called epiphyses , are chiefly cancellate bone . The epiphysial home base separates the epiphyses from the peter and is the center for longitudinal developing in children . In the bountiful , it is calcified . The ends of long cram are covered at the joints by articular cartilage , which is bully , elastic avascular tissue . Long bones are designed for weight social unit bearing and movement . gip bones consist of cancellous bone covered by a layer of wedge bone (Hoyle , 2000 . Flat bones are importance sites for sanguification and frequently provide life-sustaining organ protection . They are made of cancellous bone layered between shrink bones . Irregular bones have unique shapes affiliate to their functions .

Generally , irregular bone structure is similar to that of handle bonesBone is composed of cells , protein intercellular gist , and mineral deposits . The cells are of ternary basic types - osteoblasts , osteocytes , and osteoclasts . Osteoblasts function in bone formation by secreting bone hyaloplasm . The matrix , which consists of collagen and ground substances provides a good example in which inorganic mineral salts are deposited Osteocytes are right 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 Physiology of the nauseous Control of tidy Contraction .
