Key hormones include TRH, GnRH, GHRH, CRH, somatostatin, and dopamine, which influence the anterior pituitary's functions. TRH stimulates TSH and prolactin, GnRH is essential for reproduction, GHRH prompts growth hormone, and CRH causes ACTH release. Somatostatin and dopamine inhibit growth hormone and prolactin, respectively.
