1. The knee joint.

a. anterior cruciate

b. posterior cruciate

c. lateral collateral

slide22
4. Fractures

a. compound - bone sticks out through the skin

b. simple - bone doesn\'t stick out through the skin

slide32
5. Arthritis

a. rheumatoid arthritis - inflammation of synovial membrane - articular hyaline cartilage destroyed

6. Rickets - from deficiency of vitamin D preventing ossification. The bones actually bend because cartilage still dominates. Vitamin D is needed for calcium and phosphorus absorption.
