Mary took a whole jar of calcium chews thinking they were gummies. How would her body respond?

A.

parathyroid hormone is released, decreasing osteoclast activity

B.

calcitonin hormone is released, increasing osteoclast activity

C.

parathyroid hormone is released, increasing osteoclast activity

D.

calcitonin hormone is released, decreasing osteoclast activity

Answer and Explanation

The Correct Answer is D

A. parathyroid hormone is released, decreasing osteoclast activity
Parathyroid hormone (PTH) is released when calcium levels are low, not high. Also, PTH increases, not decreases, osteoclast activity to raise serum calcium.

B. calcitonin hormone is released, increasing osteoclast activity
Calcitonin is released during high calcium levels, but it works to decrease osteoclast activity, not increase it.

C. parathyroid hormone is released, increasing osteoclast activity
This would occur in response to low calcium, which is not the case here. Mary has excess calcium.

D. calcitonin hormone is released, decreasing osteoclast activity
 With elevated calcium levels, the thyroid gland releases calcitonin, which works to inhibit osteoclasts to reduce calcium release from bone, helping to restore balance.
