Document Summary
Blood formation in marrow, ph balance (can store h+) Attracts and removes of foreign/toxic heavy metals. Other- pneumatic (capacity to hold air like around sinuses in nose, make bones lighter and change shape of bones so are good for forensics), movement like hands/food-largest in body is patella in quadriceps), Bone composition (allows for strength and resilience to resist compression (minerals) and tension (collagen)) 10% calcium carbonate sesamoid (bones in long muscles which are subject to a lot of pull-allow repetitive accessory (anomaly can be attached to regular bones) collagen, protein, carbs. Periosteum= 2 layers, outer fibrous covering, articular cartilage at joint. Spongy bone= 1/4 weight, made of trabeculae. Epiphysis- top and bottom of growing bone. Epiphyseal plate- cartilage between epiphysis and diaphysis. when bone is fully formed this is not there and epiphysis and diaphysis merge and form one structure. Nutrient foramen- blood vessel gets into bone through nutrient foramen. External and internal layer of compact bone.
