  • A hormone that controls levels of calcium and phosphorous in the blood and influences bone loss and growth.

  • A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.

  • Parathyroid hormone (PTH) is produced by the 4 parathyroid glands, which reside behind the thyroid gland in the anterior neck. The release of PTH is normally stimulated by low calcium levels in the body.

  • Parathyroid hormone (PTH), substance produced and secreted by the parathyroid glands that regulates serum calcium concentration. Under the microscope the PTH-producing cells, called chief cells, isolated from the parathyroid glands, occur in sheets interspersed with areas of fatty tissue....
