WebJan 24, 2024 · 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. It does this by inhibiting the activity of the osteoclasts, the cells that break down bone. WebCalcitonin is a peptide hormone made up of 32 amino acid residues that is secreted from the parafollicular cells, also known as C cells. It is found in the thyroid of chordates and humans and the endostyle of invertebrates. It acts opposite to the parathyroid hormone by reducing the blood calcium levels.
