Studies for pre-nursing students include the anatomy and physiology of the human body. What hormone do the students learn inhibits bone resorption and promotes bone formation?
A) Estrogen
B) Parathyroid
C) Calcitonin
D) Progesterone
Ans: C
Feedback: Calcitonin inhibits bone resorption and promotes bone formation, estrogen inhibits bone breakdown, and parathyroid increases bone resorption. Estrogen, which inhibits bone breakdown, decreases with aging. Parathyroid hormone (PTH) increases with aging, increasing bone turnover and resorption. Progesterone is the major naturally occurring human progestogen and plays a role in the female menstrual cycle.
