Document Summary
Inorganic (calcium salts) and organic (osteoid) elements- makes it unique: highly resistant to tensile and compressive forces, tensile strength= 2500-3500 kg/cm2 (17 tons/sq in, equal to iron, compressive strength in articular regions, male adult- 270 kg/step (walking) Diaphysis (1: main part of the bone, shaft, body of the bone, composed of compact bone. Metaphysis (2: have a proximal and a distal metaphysis on either side of the diaphysis, epiphysial growth plate found on the metaphysis. Distal/proximal epiphysis (2: extreme ends of the bone, articular cartilage covers these ends, red marrow found here. Epiphysis and metaphysis will consists of compact bone over spongy bone* Medullary cavity (yellow cavity: contains yellow marrow, inside hollow part of the diaphysis, mineral storage. Periosteum- covers the bone everywhere except where there is articular cartilage. Red marrow: hematopoiesis takes place here, found in the proximal and distal epiphysis.
