MICROANATOMY

Detailed explanation-1: -The parathyroid glands have two distinct types of cells: the chief cells and the oxyphil cells . Chief cells: The chief cells manage the secretion of parathyroid hormone (PTH).

Detailed explanation-2: -Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells, C-cells, or parafollicular cells) are one of the two cell types of the parathyroid glands, along with oxyphil cells.

Detailed explanation-3: -PTH is an 84-amino acid peptide that is secreted from the parathyroid chief cells and plays an important role in the maintenance of calcium homeostasis.

Detailed explanation-4: -Parathyroid glands play a key role in maintaining the extracellular calcium concentration. The parathyroid gland is composed of two types of cells: chief and the oxyphil. Parathyroid chief cells, the main type of parathyroid gland cells, produce PTH. Oxyphil cells produce PTHrP, calcitriol, and some other factors.
