Document Summary
What is it: trabecular bone is spongy & aids shock absorption. In op lose bone tissue & get holes in the bone, causing decreased bmd & bone mass: weaker bones, more brittle, increased susceptibility to fractures. Bone cells: cells are responsible for matrix turnover in bone, osteoblasts architects, build more bone, osteoclasts eaters, remove bone, osteocytes sensors, senses strain level in bone to determine is need more/less. I. e. need to target all aspects of the femoral neck to ensure it is strong load from all angles. Increase ca+ by resorbing bone: leads to bone maintenance (cid:523)when you(cid:495)re an adult(cid:524, also leads to net loss of bone (op, occurs all throughout life, how do bones become osteoporotic, decrease osteoblast activity & increase osteoclast activity. Signs & symptoms: don(cid:495)t know if someone has op until they get a fracture, pot belly look, pain in hips when sitting for long time.
