Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.
1 Parathyroid hormone (PTH) is a protein hormone synthesized, processed and secreted by the parathyroid chief cells in response to changes in serum ionized calcium levels. 2  Drop in serum calcium levels trigger secretion of PTH via reduced binding to the calcium sensing receptors (CaSR).
