← Human Body & HealthIf a patient experiences chronic disuse of their right arm due to paralysis following a stroke, which consequence is most likely regarding bone remodeling in the affected limb?
A)Increased osteoblast activity, strengthening bone
B)Increased osteoclast activity, reducing bone density✓
C)Decreased osteoclast activity, increasing bone density
D)Balanced remodeling, no change in bone density
💡 Explanation
Chronic disuse triggers increased osteoclast activity because mechanical stress normally stimulates bone formation. Therefore, bone resorption exceeds bone formation, leading to decreased bone density and increased fracture risk, rather than strengthening due to osteoblast dominance.
