The thyroid gland is the largest endocrine gland in the human body, located in the anterior neck [1]. Its function is regulated by the anterior pituitary through the secretion of thyroid-stimulating hormone (TSH). The hypothalamic hormone that stimulates the secretion of TSH is thyrotrophin-releasing hormone (TRH). Three hormones are produced by the thyroid gland – that is, thyroxin or tetraiodothyronine (T4), triiodothyronine (T3) and calcitonin, which reduces the levels of calcium in blood. The production and secretion of T3 and T4, derived from the amino acid tyrosine, is controlled by TSH.
