Question

Quizplus · Accepted Answer

Calcitonin is secreted by the C-cells or parafollicular cells of the thyroid gland. It is released in response to high levels of calcium in the blood and helps to lower blood calcium levels by increasing calcium deposition in bones and reducing calcium reabsorption from the kidneys. Its production is not stimulated by TSH, and it is not stored in the colloid of the thyroid follicles.
