And thyroid … WebThyroid-Stimulating Hormone. The activity of the thyroid gland is regulated by thyroid-stimulating hormone (TSH), also called thyrotropin. TSH is released from the anterior pituitary in response to thyrotropin-releasing hormone (TRH) from the hypothalamus. As discussed shortly, it triggers the secretion of thyroid hormones by the thyroid gland.

WebIodine deficiency: Iodide is absolutely necessary for production of thyroid hormones; without adequate iodine intake, thyroid hormones cannot be synthesized. Historically, this problem was seen particularly in areas with iodine-deficient soils, and frank iodine deficiency has been virtually eliminated by iodine supplementation of salt. WebPathophysiology. Hormone synthesis is impaired due to apoptotic destruction of the thyroid cells. The sick cells exhibit a defect in organic binding of thyroid iodide, as evidenced by a positive perchlorate discharge test (see Chapter 11 ). In addition, release of iodoproteins, mostly Tg, is enhanced by cell lysis.

WebThe thyroid follicles produce two hormones, Thyroxine or T 4 and Triiodothyronine or T 3.They are synthesized from tyrosine, an amino acid, and iodine.
