Osteology | Study of bones |
Similarities to other tissues: | -highly vascular -it is supporting |
Differences to other tissues: | -hard tissue -calcium salts |
Functions of bone tissue: | 1. Provides rigid framework for support 2. Protects vital organs 3. Encloses blood forming elements 4. Metabolic role-ready source of Calcium (Ca++) |
Properties of bone: | 1. Tensile strength- ability to bend; any lateral movement placed on the bone 2. Compressive strength- any superior or inferior movement or weight placed on the bone 3. Ability to remodel or change- growth, bigger, stronger, wider; breaks: it can fix itse |
Ligament | Connect bone to bone |
Tendon | Connect bone to muscle |
Bonecell | Make up the composition of bone and allow it to perform its functions |
Calcium Salts | -70% -compressive strength -middle part of bone -dense |
Organic Matrix | -30% -tensile strength -distal ends of bone -sponge/porous -collagen fiber allows bending to occur |
