Skeletal SystemWhat argon the five primary functions of the skeletal systemThere ar 206 swot up in the human body , sh bed into quartet categories Long tusks (eg , femur , short fig ups (eg , metacarpals , monotonic tusks (eg sternum , and irregular bone (eg , vertebrae . The shape and building of a specific bone argon determined by its function and the forces exerted on it . swot up atomic issuance 18 constructed of cellular (trabecular or cortical ( crush ) bone waver . Long bones are shaped standardised rods or shafts with rounded ends . The shaft , cognise as the diapysis , is to begin with cortical bone . The ends of the long bones , called epiphyses , are originally cancellated bone . The epiphyseal home base separates the epiphyses from the light beam and is the center for longitudinal growth in children . In the bountiful , 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 building block bearing and movement . Short bones consist of cancellous bone covered by a layer of hale bone (Hoyle , 2000 . Flat bones are importance sites for hemogenesis and frequently provide vital organ protection . They are made of cancellous bone layered between reduce bones . Irregular bones have unique shapes bring together to their functions . Generally , irregular bone structure is similar to that of look bonesBone is composed of cells , protein intercellular substance , and mineral deposits . The cells are of triple 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 model in which inorganic mineral salts are deposited Osteo cytes are advanced bone cells involved in b! one-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 Muscular Contraction .
