Hypothalamic-Pituitary-Thyroid Axis - an overview - ScienceDirect The hypothalamic-pituitary-thyroid axis (HPT) is responsible for controlling the synthesis and secretion of two thyroid hormones: triiodothyronine (T3) and tetraiodothyronine or thyroxine (T4). 17 Thyrotropin-releasing hormone (TRH), produced in the hypothalamus, acts on thyrotrophs of the adenohypophysis to stimulate the synthesis and release of thyroid-stimulating hormone (TSH), which stimulates the thyroid gland to secrete T4 and T3. 17 The axis is controlled by negative feedback on the ... UpToDate Specifically, the hypothalamic-pituitary axis directly affects the functions of the thyroid gland, the adrenal gland, and the gonads, as well as influencing growth, milk production, and water balance ( table 1) [ 1-4 ]. The hypothalamic-pituitary axis will be reviewed here. The functions of the hypothalamic and pituitary hormones are discussed ...

The hypothalamus-pituitary-thyroid (HPT) axis determines the set point of thyroid hormone (TH) production. Hypothalamic thyrotropin-releasing hormone (TRH) stimulates the synthesis and secretion of pituitary thyrotropin (thyroid-stimulating hormone, TSH), which acts at the thyroid to stimulate all steps of TH biosynthesis and secretion. The THs thyroxine (T4) and triiodothyronine (T3) control the secretion of TRH and TSH by negative feedback to maintain physiological levels of the ...

The Role of the Hypothalamus and Pituitary Gland In Thyroid Health Hypothalamic-pituitary-thyroid axis. With regards to thyroid health the hypothalamus secretes a hormone called thyrotropin-releasing hormone (TRH), which in turn stimulates the pituitary to release thyroid stimulating hormone (TSH), and this hormone stimulates the thyroid gland to secrete the hormones thyroxine (T4) and tri-iodothyronine (T3). ... Hypothalamic-pituitary-thyroid axis - Wikipedia The hypothalamic-pituitary-thyroid axis is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland. The hypothalamus senses low circulating levels of thyroid hormone and responds by releasing thyrotropin-releasing hormone. The TRH stimulates the anterior pituitary to produce thyroid-stimulating hormone. The TSH, in turn, stimulates the ... Central Regulation of Hypothalamic-Pituitary-Thyroid Axis Under ... I. Introduction. The hypothalamic-pituitary-thyroid (HPT) axis primarily functions to maintain normal, circulating levels of thyroid hormone that is essential for the biological function of all tissues, including brain development; regulation of cardiovascular, bone, and liver function; food intake; and energy expenditure among many others ().Key to this regulatory system is a group of neurons ... Thyroid Hormone Synthesis Pathway: Step-By-Step Flow Chart - EZmed The 3 structures communicate and work together to synthesize and regulate thyroid hormone. Together they are called the hypothalamic-pituitary-thyroid axis, or HPT axis for short. The HPT axis is a self-regulatory circuit that balances thyroid hormone levels in the blood and maintains thyroid homeostasis in the body.
