Which event occurs during stress activation of the hypothalamic-pituitary-adrenal (HPA) axis?

Question

Quizplus · Accepted Answer

During stress activation of the HPA axis, neurotransmitters like norepinephrine and acetylcholine regulate the release of corticotrophin-releasing factor (CRF) from the hypothalamus, which in turn stimulates the release of adrenocorticotropic hormone (ACTH) from the pituitary gland, leading to the release of cortisol from the adrenal gland. Option B is incorrect because ACTH stimulates the release of cortisol, and option C is incorrect because cortisol feeds back to inhibit HPA activation. Option D is also incorrect because glucocorticoids feedback to inhibit the hippocampus, not stimulate it.
