WebEarn-Hui Gan, Richard Quinton, in Progress in Brain Research, 2010. Regulation of thyrotroph function. Thyroid hormone secretion is necessarily very tightly controlled, being essential for energy homeostasis and basal heat production (Morley, 1981).Thyrotrophin-releasing hormone (TRH) stimulates the release of both TSH and PRL from the anterior pituitary … WebMar 23, 2024 · The TSH that is released from the anterior pituitary gland will travel through the bloodstream and bind to TSH receptors on thyroid follicular cells.

WebJan 21, 2024 · TSH. The primary hormone in this complex process is thyroid-stimulating hormone (TSH). TSH is released by the pituitary gland and helps "stimulate" the thyroid gland to make more hormones when the body needs it. Thus, if thyroid hormones are low in your blood, the pituitary will release more TSH to increase production. WebThe 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. Webhave important roles in detecting and controlling thyroxine levels.
