Alternative names for calcitonin Calcitonin is a hormone that is produced in humans by the parafollicular cells (commonly known as C-cells) of the thyroid gland. Calcitonin is involved in helping to regulate levels of calcium and phosphate in the blood, opposing the action of parathyroid hormone.

What is Calcitonin? Calcitonin is a hormone that the C-cells in the thyroid gland produce and release. It opposes the action of the parathyroid hormone, helping to regulate the blood’s calcium and phosphate levels. Calcitonin works to control calcium and potassium levels.

Thyroid-Related Calcium Deficiency Calcitonin Hormone. A hormone called calcitonin is secreted by the thyroid gland and works in conjunction with parathyroid hormone, or PTH, which is secreted by the parathyroid gland to maintain blood serum calcium levels. Calcitonin works to reduce the amount of calcium your body takes from its own bones.

Calcitonin The calcitonin receptor, found on osteoclasts, and in the kidney and regions of the brain, is a G protein-coupled receptor, which is coupled by Gs to adenylate cyclase and thereby to the generation of cAMP in target cells.

Parathyroid hormone While PTH acts to increase the concentration of ionic calcium (Ca 2+) in the blood, calcitonin, a hormone produced by the parafollicular cells (C cells) of the thyroid gland, acts to decrease ionic calcium concentration.t enhances active reabsorption of calcium and magnesium from distal tubules and the thick ascending limb. As bone is degraded, both calcium and phosphate are released. It also decreases the reabsorption of phosphate, with a net loss in plasma phosphate concentration.

Calcitonin Calcitonin is a 32-amino acid linear polypeptide hormone that is produced in humans primarily by the parafollicular cells of the thyroid, and in many other animals in the ultimopharyngeal body. It acts to reduce blood calcium, opposing the effects of parathyroid hormone. Calcitonin has been found in fish, reptiles, birds, and mammals. Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant in the regulation of norma

- The hormones parathyroid hormone (PTH) and calcitonin help regulate blood calcium levels. Calcitonin, secreted by the thyroid gland inhibits osteoclasts and stimulates osteoblasts, thus decreasing blood calcium levels. Parathyroid hormone is secreted by the parathyroid glands, which are on the posterior side of the thyroid. Parathyroid hormone inhibits osteoblasts, stimulates osteoclasts, reduces the output of calcium by the kidneys and promotes the absorption of calcium by the small intestines, thus increasing blood calcium levels.

The Thyroid Gland and its Hormones Calcitonin. Calcitonin is produced by the C cells of the thyroid gland and is released when levels of calcium in the blood are increased. Its role is to decrease the amount of calcium in the blood. It has the opposite action to parathyroid hormone, which increases the amount of calcium in the blood when levels fall.hen calcium levels are high, more calcitonin is released from the gland. When calcium levels fall, the release of calcitonin also falls. Some other hormones play a role in the regulation of calcitonin. Somatostatin is a hormone which reduces the release of calcitonin, and gastrin promotes the release of calcitonin.

- So, if there is excess calcium floating around your bloodstream, your thyroid gland produces and secretes calcitonin, which sweeps up the excess calcium and deposits it in your bones. Later on, we will learn about the antagonist of calcitonin, called parathyroid hormone (PTH).

Calcitonin Calcitonin, also called thyrocalcitonin , a protein hormone synthesized and secreted in humans and other mammals primarily by parafollicular cells (C cells) in the thyroid gland. In birds, fishes, and other nonmammalian vertebrates, calcitonin is secreted by cells of the glandular ultimobranchial bodies.

Calcitonin Glossary. Calcitonin is a hormone known to participate in calcium and phosphorus metabolism. In mammals, the major source of calcitonin is from the parafollicular or C cells in the thyroid gland, but it is also synthesized in a wide variety of other tissues, including the lung and intestinal tract.

Thyroid and Parathyroid Glands Calcitonin decreases the amount of calcium and phosphorus in the blood. It does this by slowing the activity of cells found in bone, called osteoclasts. These cells cause calcium to be released as they 'clean' bone.

Calcitonin In particular, calcitonin has the ability to decrease blood calcium levels at least in part by effects on two well-studied target organs: Bone: Calcitonin suppresses resorption of bone by inhibiting the activity of osteoclasts, a cell type that digests bone matrix, releasing calcium and phosphorus into blood.
