Final answer:
When TRH is released, it stimulates the pituitary gland to produce TSH, which in turn stimulates the thyroid gland to secrete thyroid hormones. The effects of TRH on the body include regulating metabolism, growth, and development. TRH release and TSH production are regulated by feedback mechanisms to maintain thyroid hormone levels within a normal range.
Step-by-step explanation:
When thyrotropin-releasing hormone (TRH) is released from the hypothalamus, it stimulates the pituitary gland to produce thyroid-stimulating hormone (TSH). TSH then stimulates the thyroid gland to secrete thyroid hormones (T4 and T3). The release of TRH and subsequent production of TSH is part of a negative feedback loop, where high levels of thyroid hormones inhibit TRH and TSH release.
The effects of TRH on the body include the stimulation of TSH production, which in turn stimulates the thyroid gland to secrete thyroid hormones. These hormones are crucial for regulating metabolism, growth, and development in the body. Additionally, TRH release and TSH production are regulated by feedback mechanisms to maintain thyroid hormone levels within a normal range.
