Although not well elucidated, 1,25-(OH) 2 D3 appears to exert a mild inhibitory effect on the parathyroid gland as well. In the blood, the sensitive process of calcium and phosphate homeostasis is maintained primarily by an appropriately functioning parathyroid gland. The thyroid gland is a very vascular organ that is located in the neck.It consists of two lobes, one on each side of the trachea, just below the larynx or voice box.The two lobes are connected by a narrow band of tissue called the isthmus.Internally, the gland consists of follicles, which produce thyroxine and triiodothyronine hormones.
