Which of the following is secreted by TRH stimulation?
TRH is derived from a pro-TRH peptide. Like other hypothalamic-releasing hormones, TRH reaches the anterior pituitary the hypothalamic-pituitary poal circulation. It interacts with specific receptors on pituitary thyrotrophs to release TSH and on mammotrophs to release prolactin. Ref: Textbook of Endocrine Physiology edited by William J. Kovacs, Sergio R.
