← Human Body & HealthFollowing immobilization of upper arm joints, which of the following pathological bone responses?
A)Joint cartilage thinning occurs at contact✓
B)Increased bone mineral density expected
C)Enhanced joint range of motion forms
D)Tendon hypertrophy will increase loading

Immobilization causes decreased joint loading, thereby resulting disuse osteoporosis and degradation to cartilage at contact surfaces due to malnutrition, therefore cartilage will thin rather than building bone material. Hypertrophy won't occur.
