The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) 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 (Triiodothyronine (T3) and Th… Webb11 jan. 2024 · The thyroid gland is regulated by a negative feedback loop.

Webb11 jan. 2024 · The thyroid gland is regulated by a negative feedback loop. The loop includes the hypothalamus and pituitary gland in addition to the thyroid. Here’s how thyroid regulation works. The hypothalamus secretes thyrotropin-releasing hormone, or TRH. TRH stimulates the pituitary gland to produce thyroid-stimulating hormone, or TSH. Webb1 nov. 2024 · Regulation of thyroid function The production of thyroid hormones is regulated by a negative feedback loop ( Figure 3 ). Low circulating levels of T4 and T3 stimulate the hypothalamus to release thyrotrophin-releasing hormone (TRH) which acts on the anterior pituitary gland, resulting in the release of thyroid-stimulating hormone (TSH). botella.my

Webb20 nov. 2015 · The integrated control involves several major control loops, a negative feedback control of thyroid hormones on pituitary TSH and hypothalamic TRH, positive stimulatory control of TRH on TSH, ultrashort feedback of TSH on its own secretion, and feedforward control of deiodinases by TSH. WebbWhat is a feedback loop in the endocrine system? Most endocrine activities are regulated by a series of complex feedback loops. These feedback loops work like a thermostat that responds to temperature changes by telling a furnace to turn on and off. When it’s cold, the thermostat signals the furnace to turn on and make heat.
