A patient suffers degeneration of cartilage covering the ends of bones. Which consequence is most likely during movement?

A. Increased production of bone marrow
B. Increased friction between bones
✓
C. Increased calcium storage
D. Increased bone flexibility

📝 Explanation

Correct: Loss of articular cartilage increases friction, causing pain and restricted movement. A: Bone marrow production is unrelated. C: Calcium storage is unaffected. D: Bone flexibility does not increase. Concept: Function of articular cartilage.
