III. Physiology

  1. Parathyroid Gland regulates extracellular calcium
    1. Parathyroid synthesizes Parathyroid Hormone (PTH)
  2. Parathyroid increases PTH release when calcium falls
    1. See Parathyroid Hormone for PTH physiology
    2. PTH rises when calcium falls, and increases calcium
    3. PTH falls when calcium rises, and decreases calcium

Ontology: Parathyroid gland (C0030518)

Definition (CSP) small paired endocrine glands in the region of the thyroid gland which secrete parathyroid hormone and are concerned with the metabolism of calcium and phosphorus.
Definition (MSH) Two pairs of small oval-shaped glands located in the front and the base of the NECK and adjacent to the two lobes of THYROID GLAND. They secrete PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body.
Definition (NCI) One of two small paired endocrine glands, superior and inferior, usually found embedded in the connective tissue capsule on the posterior surface of the thyroid gland; these glands secrete parathyroid hormone that regulates the metabolism of calcium and phosphorus. The parenchyma is composed of chief and oxyphilic cells arranged in anastomosing cords.
