parathyroid gland


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

par·a·thy·roid gland

[TA]
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; they secrete parathyroid hormone that regulates metabolism of calcium and phosphorus. The parenchyma is composed of chief and oxyphilic cells arranged in anastomosing cords. Inadvertent removal of all parathyroid glands, as during thyroidectomy, produces tetany and may be fatal in the absence of hormone replacement therapy.

parathyroid gland

n.
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.

parathyroid gland

A small gland located at the posterior aspect of the thyroid gland, which regulates calcium by secreting PTH; is critical to calcium and phosphorus metabolism, and magnesium balance and in normal bone mineralization. See PTH.
