Document Summary
A cylinder is a very strong support system. We want our bone to be as light as possible but as light as possible. They are able to withstand a lot of pressure. Joints aligned by cartilage, we want joint surface to have lots of cartilage and be broad. Brow bones from growth plate (near the cartilage), adult have thin growth plate = cartilage less prominent. Ca important for function and action of cells including muscle cells. Organic 35% (most of it is collagen), inorganic 65%, bone is alive! Bone are being made and removed all the time = remodelling. Mechanical stresses greater than the bone can tolerate = fracture. Bone is made up of different components, other components around the bone (muscle, blood vessel, skin, etc) Multiple tissue types = wound healing according to their proliferation ability. Healing of a tissue is either rege or scarring.
