Title: Human parathyroid gland (I)
Description:
Parathyroid gland. (A, D): Stain Azan. (C1, C2): Scheme. (B, D): Stain eosin.
The survey in (A, C1) of the glandula parathyreoidea shows the presence of blue-stained septa derived from a thin capsule (not shown), embedding a richly vascularized network of blood vessels and capillaries. The white cells (6) are fat cells.
The organ contains two cell types: clear chief cells or lightly stained cells (4) with a centrally located round nucleus and a light acidophilic cytoplasm. The cells produce parathyroid hormone PTH. The oxyphilic cells or chromophilic cells or Welsh cells (5) are slightly larger than the former cells and are stained more intensely with eosin stain due to the presence of numerous mitochondria.
The PTH regulates the level of calcium and phosphate in the blood. It is an antagonist of the calcitonin hormone.
PTH also promotes the phosphate secretion in the kidneys.
