Thyroid-stimulating hormone receptor and thyroid hormone
The release of these peptides is stimulated by depolarization through a calcium-dependent process. Define thyrotropin-releasing hormone. thyrotropin-releasing hormone synonyms, A hormone secreted by the hypothalamus that stimulates release of thyroid TSH is secreted by the anterior pituitary gland and is itself under the control of thyrotropin-releasing hormone (TRH). TRH is secreted by the hypothalamus.

TRH is present throughout the external zone of the median eminence in axon terminals that originate from a group of neurons located in the paraventricular nucleus (PVN), a region that corresponds to the “thyrotropic area” of the hypothalamus. Thyrotropin-releasing hormone release from rat pancreas is stimulated by serotonin but inhibited by carbachol. Lamberton P, Wu P, Jackson IM. Immunoreactive TRH (IR-TRH) has been found in the mammalian pancreas, with several studies documenting high … Thyrotropin-releasing hormone (TRH) is a tripeptide hormone secreted by the hypothalamus that stimulates the release of thyrotropin. This tripeptide is involved in the regulation of the hypothalamic pituitary-thyroid axis; it stimulates the synthesis and release from the anterior pituitary of th thyroid-stimulating hormone (TSH) thyrotropin.

Meaning of stimulating in Turkish english dictionary - İngilizce
This hormone production system is regulated by a feedback loop so that when the levels of the thyroid hormones (thyroxine and triiodothyronine) increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone. This system allows the body to maintain a constant level of thyroid hormones in the body. TRH, also known as thyrotropin-releasing factor, is secreted by the anterior region of the hypothalamus, along with a number of identified and well-characterized releasing hormones. TRH infusion has been used in clinical testing to determine if the pituitary gland is responsive to its stimulation in producing thyroid-stimulating hormone (TSH). ‘Suckling, stress, dehydration, exercise, sexual intercourse and sleep increase the basal secretion rate from the pituitary gland, as do estrogen, thyrotropin-releasing hormone and possibly serotonin.’ ‘Low levels of thyroid hormone result in increased levels of the thyrotropin-releasing hormone, which increases prolactin secretion.’ Thyrotropin releasing hormone (TRH) is secreted by hypothalamus.
120 The smallest dose of TRH that releases TSH also releases PRL in humans. 121 However, immunoneutralization of endogenous TRH with TRH antisera only causes suppression of basal PRL levels in rats in some studies 122 but not in others 123,124; mice with …
