Summary of Calcitonin
Calcitonin, a polypeptide hormone produced by the parafollicular or C cells of the thyroid gland, acts by inhibiting bone resorption by osteoclasts, in this way decreasing plasma calcium concentration. Its role in human metabolism however is uncertain, since neither a decrease – as in a thyroidectomy – or an increase – as in thyroid tumors – cause a derangement of calcium metabolism.
