The thyroid gland is part of the endocrine system responsible for production of thyroid hormones-triiodoiodine(T3) and thyroxine(T4). These hormones regulate the rate of metabolism and affect the growth and rate of function of other systems in the body. The control of thyroid lies in hypothalamus and pituitary, beginning from thyrotropin-releasing-hormone(TRH) in the former followed by thyroid-stimulating-hormone(TSH)in the latter.
