TSHB is a hormone synthesized and secreted by thyrotrope cells in the anterior pituitary gland which regulates the endocrine function of the T gland. Stimulates the gland to secrete the hormones (T4) and triiodothyronine (T3). Production is controlled by a Thyrotropin Releasing Hormone, (TRH), which is manufactured in the hypothalamus and transported to the Anterior Pituitary gland, where it increases production and release. Somatostatin is also produced by the hypothalamus, and has an opposite effect on the pituitary production, decreasing or inhibiting its release. The level of T hormones (T3 and T4) in the blood have an additional effect on the pituitary release of TSH, When the levels of T3 and T4 are low, the production is increased, and conversely, when levels of T3 and T4 are high, then production is decreased. This effect creates a regulatory negative feedback loop.
