← Human Body & HealthIf osteocytes within bone experience reduced mechanical loading due to prolonged bed rest, which consequence follows concerning bone density?
A)Density increases at fracture sites
B)Density decreases due to resorption✓
C)Density remains constant overall
D)Density redistribution favors growth
💡 Explanation
Reduced mechanical loading causes increased osteoclast activity via decreased osteocyte signaling, which leads to bone resorption through RANKL pathway activation. Bone density decreases because of the elevated resorption; therefore, overall bone mass is reduced rather than remaining constant or favoring increased deposition.
