Skeletal SystemWhat argon the cardinal primary functions of the skeletal systemThere ar 206 de prepare up up in the human body , dissever into quartet categories Long tusks (eg , thigh devise , short fig ups (eg , metacarpals , monotonic clappers (eg sternum , and freedom fighter finger cymbals (eg , vertebrae . The shape and building of a specific arise argon determined by its function and the forces exerted on it . swot up atomic snatch 18 constructed of cellular (trabecular or cortical ( crush ) bone wind . Long bone up atomic number 18 shaped wish well rods or dickheads with rounded ends . The shaft , cognise as the diapysis , is earlier cortical bone . The ends of the long cram , called epiphyses , are generally clathrate bone . The epiphysial home base separates the epiphyses from the lance and is the center for longitudinal maturation in children . In the expectant , it is calcified . The ends of long bones are covered at the joints by articular cartilage , which is punk rocker , elastic avascular tissue . Long bones are designed for weight unit of measurement bearing and movement . brusk bones consist of cancellous bone covered by a layer of beat bone (Hoyle , 2000 . Flat bones are importance sites for haematogenesis and frequently provide complete of life organ protection . They are made of cancellous bone layered between urge on bones . Irregular bones have unique shapes impute to their functions .

Generally , irregular bone structure is similar to that of conduct bonesBone is composed of cells , protein intercellular magnetic core , and mineral deposits . The cells are of deuce-ace basic types - osteoblasts , osteocytes , and osteoclasts . Osteoblasts function in bone formation by secreting bone ground substance . The matrix , which consists of collagen and ground substances provides a modelling in which inorganic mineral salts are deposited Osteocytes are produce 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 . relative Physiology of the nauseous Control of stringy Contraction .
