{s} pertaining to the parathyroid, pertaining to the small secretory glands located behind the thyroid gland (Anatomy)
Tiny glands located in the neck, which produce a hormone known as parathyroid hormone that regulates the level of calcium in the blood There are usually two glands on each side of the neck behind the thyroid but they may be in other locations in the neck and even in the chest
Any of usually four small kidney-shaped glands that lie in pairs near or within the posterior surface of the thyroid gland and secrete parathyroid hormone. Endocrine gland, two to eight of which are embedded in each side of the thyroid gland. It secretes parathyroid hormone, which regulates blood calcium and phosphorus levels. When calcium in body fluids drops, increased hormone secretion releases calcium from bone into the bloodstream (see calcium deficiency). The hormone also increases excretion of phosphate in the urine, lowering blood concentrations, and may play a role in magnesium metabolism. When thyroid removal is required, the parathyroid glands must be separated out and left in place. See also endocrine system
hormone synthesized and released into the blood stream by the parathyroid glands; regulates phosphorus and calcium in the body and functions in neuromuscular excitation and blood clotting
