Which of the following is NOT an application of calcitonin?

• A. To increase bone mass moderately
• B. To improve bone strength in men
• C. To decrease the rate osteoclasts absorb bone
• D. Used in postmenopausal women

Answer: (B)

Calcitonin is a hormone known for its role in calcium regulation and bone metabolism. Specifically, it is secreted by the thyroid gland and works primarily to lower blood calcium levels. One of its key functions is to inhibit the activity of osteoclasts, the cells responsible for bone resorption, thereby decreasing the rate at which bone is absorbed. When considering its applications, calcitonin can indeed help in various scenarios: it can moderately increase bone mass in certain conditions, assist in decreasing bone resorption after menopause, and be beneficial in treating conditions related to high calcium levels or excessive bone turnover. The choice that stands out as not being an application of calcitonin is its effectiveness in improving bone strength specifically in men. While calcitonin does have applications in women, particularly postmenopausal women who experience bone density loss due to estrogen deficiency, its role in improving bone strength in men is not well-established or recognized in the same manner. Therefore, this choice accurately reflects the limitations of calcitonin's effectiveness in the context provided, making it the correct response.
