GLANDULA PARATIROIDES PDF

They differ from it in structure, being composed of masses of cells arranged in a more or less columnar fashion with numerous intervening capillaries. In man, they number four as a rule; fewer than four were found in less than 1 per cent. In addition, numerous minute islands of parathyroid tissue may be found scattered in the connective tissue and fat of the neck around the parathyroid glands proper, and quite distinct from them accessory parathyroid glands. A pair of diverticula arise from the fifth branchial pouch and form what are termed the ultimo-branchial bodies : these fuse with the thyroid gland, but probably contribute no true thyroid tissue. Most of the cells are clear, but some, larger in size, contain oxyphil granules.

The superior, usually two in number, are the more constant in position, and are situated, one on either side, at the level of the lower border of the cricoid cartilage, behind the junction of the pharynx and esophagus.

The inferior, also usually two in number, may be applied to the lower edge of the lateral lobes, or placed at some little distance below the thyroid gland, or found in relation to one of the inferior thyroid veins.

Extirpación de las glándulas paratiroideas

Though they are small, the parathyroid glands are big players in the endocrine system. They have a very important purpose: keeping bones strong, the nervous system running and the muscles pumping. The parathyroids are four mustard-colored glands that function as one. They are located behind the thyroid, which is a gland that stretches across the front of the neck, below the voice box. Each parathyroid gland is around the size of a pea, or 3 to 5 millimeters in diameter and 30 to 60 milligrams in weight, according to the University of Michigan. While the names are similar and they are physically near each other, the functions of the thyroid and the parathyroid are unrelated. The parathyroids release parathyroid hormone PTH , which regulates how much calcium is in the blood.
