Question

Quizplus · Accepted Answer

The hypothalamus and pituitary gland are part of the neuroendocrine system and they work together to stimulate the thyroid gland to release thyroid hormones. The hypothalamus secretes thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to release thyroid-stimulating hormone (TSH). TSH, in turn, stimulates the thyroid gland to release TH. This is an example of a feedback loop where changing levels of TH in the blood signal the hypothalamus and pituitary to either increase or decrease TRH and TSH secretion, respectively, in order to maintain homeostasis.
