Question

Quizplus · Accepted Answer

When cortisol levels in the blood drop, it triggers a negative feedback loop that stimulates the release of corticotropin releasing hormone (CRH) from the hypothalamus. CRH, in turn, stimulates the release of adrenocorticotropin (ACTH) from the anterior pituitary gland. ACTH then stimulates the adrenal glands to produce and release cortisol. Therefore, the correct answer is corticotropin releasing hormone (C).
