It increases deposition of calcium and phosphate in the bone and lowers levels in the blood, so effectively it inhibits calcium resorption by binding to a specific receptor on the osteoclasts, and inhibits their action. The thyroid is a small butterfly-shaped gland that lies over and flat against the windpipe in the throat. calcitonin [kal″sĭ-to´nin] a polypeptide hormone secreted by the parafollicular or C cells of the thyroid gland; it is involved in plasma calcium homeostasis and acts to decrease the rate of bone resorption. The slightest changes in its metabolism may therefore have substantial implications. The thyroid gland is made up of thousands of follicles, which are small spheres lined with follicular cells.

Calcitonin has been preserved during the transition from ocean-based life to land dwellers and is phylogenetically older than parathyroid hormone. Calcitonin is a hormone secreted by the thyroid gland that aids in calcium homeostasis. Calcitonin is a 32 amino acid hormone secreted by the C-cells of the thyroid gland. Calcitonin is a hormone secreted by the thyroid gland that reduces the concentration of blood calcium level when it has risen to an above normal … Calcitonin (thyrocalcitonin) is a hormone produced by C cells in the thyroid gland. This hormone is also referred to as thyrocalcitonin. Calcitonin does not affect the metabolic turnover, but interferes with the metabolism of calcium (and phosphate) ions, which are responsible (among other functions) for the stability of membrane potential. The function of calcitonin in the human body is unknown; what is known is that it is a hormone produced by C-cells in the thyroid. What is calcitonin. The main action of calcitonin is on the bone. The thyroid gland is a small butterfly-shaped gland that lies over and flat against the windpipe in the throat. Calcitonin comes from the parafollicular cells, or C cells, of the thyroid gland which is a gland located in the neck that looks like two thumbs hooked together in the shape of a “V”.

Calcitonin is a hormone produced by special cells in your thyroid gland called C-cells. Calcitonin is a protein hormone that, in humans and other mammals, is mainly secreted by the parafollicular cells (C cells) of the thyroid gland. It produces several hormones, primarily T4 (thyroxine) and T3 (triiodothyronine), that help control the rate of Calcitonin … Calcitonin secretion is stimulated by increases in the serum calcium concentration and calcitonin protects against the development of hypercalcemia.
