Adrenocorticotrophic hormone (ACTH) secretion increases

A. True The median eminence secretes corticotropin-releasing hormone (CRH), the releasing hormone for ACTH.

B. False Aldosterone secretion is regulated mainly by the renin/angiotensin system.

C. True This negative feedback helps to maintain the blood cortisol level.

D. True This is part of the circadian rhythm which produces high morning cortisol levels.

E. True Most forms of stress increase ACTH output by their neural input to the median eminence of the hypothalamus where CRH is formed.
