The thyroid gland, located immediately below the larynx on each side of and anterior to the trachea, is one of the largest of the endocrine glands, normally weighing 15 to 20 grams in adults. The thyroid secretes two major metabolic hormones, thyroxine and triiodothyronine, commonly called T4 and T3, respectively. Both of these hormones profoundly increase the metabolic rate of the body. Complete lack of thyroid secretion usually causes the basal metabolic rate to fall 40% to 50% below normal, and extreme excesses of thyroid secretion can increase the basal metabolic rate to 60% to 100% above normal. Thyroid secretion is controlled primarily by thyroid- stimulating hormone (TSH) secreted by the anterior pituitary gland.
