Secretion of thyroid-stimulating hormone is controlled by which gland?

Explanation:
TSH is produced by the anterior pituitary, but its release is controlled by the hypothalamus. The hypothalamus secretes thyrotropin-releasing hormone (TRH), which travels to the anterior pituitary and stimulates it to secrete TSH. This links the brain’s regulatory center to the thyroid gland: when thyroid hormone levels are low, TRH (and thus TSH) increase to boost thyroid output; when thyroid hormones are high, feedback reduces TRH and TSH.
