Question

Quizplus · Accepted Answer

Hormone secretion from the anterior pituitary gland is controlled by hypophysiotropic hormones from the hypothalamus, which regulate the release of anterior pituitary hormones. The secretion of anterior pituitary hormones is also regulated by negative-feedback action of target-tissue hormones, which inhibit further secretion of the hormone. Therefore, both (a) and (c) above are correct.
