1. Skeletal System FORM AND FUNCTION

2. Skeletal system: The Framework  Two basic parts –Cartilage  Cartilage graft –Bone

3. A: Cartilage Hyaline Cartilage Flexible support Most abundant Nose Ribs Joint linings Elastic Cartilage More stretchy Ears Epiglottis Fibro-cartilage Very strong High stress areas Knee Vertebrae

4. B: Bones Spongy Bone: Strength and support Bone Marrow: Blood cell production Compact Bone: Protection Mineral storage

5. C: Connections  Ligament: –Made of cartilage –Connects bone to bone  Tendon: –Made of cartilage –Connects muscle to bone

6. The real deal

7. Connections continued  Joints: –Places where two bones meet –4 types  Fixed  Hinge  Ball and socket  Gliding
