Thyroid Function

The thyroid is regulated by the hormone TSH which is produced in the hypophysis. Hormones as Thyroxin (T4), Triiodthyronine (T3) and Calcitonin are produced out of the precursor protein thyreoglobulin (Tg). Among others the thyroid regulates blood pressure, the generation of heat as well as bone metabolism and growth. Hypothyroidism is one of the main causes for the formation of a crop.
