This study was carried out on the anatomical structure, position and dimension of the parathyroid gland. Also this study was attended to the histological, histochemical and ultrastructure of the cells of the parathyroid gland. It was seen at the dorsal border on the cranial pole of the thyroid gland as definite circumscribed structure. Also the gland is located as separate parathyroid structure in the architecture of the thyroid gland. The gland separated from the architecture of the thyroid gland by CT capsule. The gland parenchyma consisted of two groups of cells; chief cells which were numerous and classified to light and dark cells and oxyphilic cells that were fewer in number and randomly distributed between the chief cells.
