Final answer:
The anterior pituitary hormone that inhibits TRH production is Thyroid Stimulating Hormone (TSH). When TSH is released, it stimulates the thyroid gland to produce and release thyroid hormones. High levels of thyroid hormones in the blood provide negative feedback to the hypothalamus and anterior pituitary, inhibiting further production and release of TRH and TSH.
Step-by-step explanation:
The anterior pituitary hormone that acts back on the hypothalamus to inhibit TRH production is Thyroid Stimulating Hormone (TSH). TSH is produced by the anterior pituitary and released in response to the hypothalamic hormone, Thyrotropin Releasing Hormone (TRH). When TSH is released, it stimulates the thyroid gland to produce and release thyroid hormones. However, when the levels of the thyroid hormones in the blood are high, they provide negative feedback to the hypothalamus and anterior pituitary, inhibiting further production and release of TRH and TSH, respectively.
