| 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 |
