Question

Quizplus · Accepted Answer

Calcitonin is a hormone that is secreted in response to hypercalcaemia, or high levels of calcium in the blood. It functions to decrease blood calcium levels by inhibiting the activity of osteoclasts, cells that break down bone tissue and release calcium into the blood. It does not enhance the effect of parathyroid hormone, is not synthesized in the skin, and a deficiency does not produce diabetes insipidus.
