1. Homeostatic Imbalances of the Skeletal System Osteoarthritis

2. I. Bone Fractures femur fracture clavicle fracture

3. Radius fracture and dislocation of ulna Fracture of metacarpel

4. humerus fracture

5. fracture of humerus fracture of femur

6. fracture of the radius Skull fracture

7. II. Arthritis A. Osteoarthritis - Chronic degeneration of the cartilage due to wear and tear

8. -often results in growth of extra bone tissue = bone spurs Osteoarthritis:

10. Osteoarthritis of the hands

11. B. Rheumatoid Arthritis 1) Autoimmune disease- immune system destroys cartilage 2) Scar tissue forms which ossifies, fusing bones 3) Can cause deformity and crippling

12. Rheumatoid Arthritis

13. III. Osteoporosis - A. Bone thinning disease that can lead to fractures, especially the spine and head of femur B. Risk factors: 1) poor diet - calcium, vit. D 2) lack of exercise 3) smoking 4) menopause 5) small build 6) genetics

18. IV. Rickets -Bones fail to calcify -Due to lack of calcium and/or vitamin D -soft bones lead to bowed legs
