Human Body & Health

An elderly patient experiences chronic psychological stress, compounded by limited mobility. Which outcome concerning bone remodeling becomes most likely in this scenario?

A)Increased osteoblast differentiation via OPG
B)Enhanced bone density due to calcitonin
C)Reduced bone formation from cortisol
D)Elevated estrogen protection of osteocytes

💡 Explanation

Chronic stress elevates cortisol levels, which inhibits osteoblast activity, thereby decreasing bone formation and leading to bone loss. This is because cortisol reduces bone formation, rather than the other hormones increasing bone density; therefore, reduced bone formation is most likely.
