Predict the effects of a drug that increases adrenocorticotropic hormone (ACTH) synthesis.
A) increase in glucocorticoid production
B) increase in release of corticotropin-releasing hormone (CRH)
C) decrease in cortisol release
D) decrease in release of corticotropin-releasing hormone (CRH)

Question

Quizplus · Accepted Answer

ACTH stimulates the production of glucocorticoids, which are a type of steroid hormone released by the adrenal cortex. Therefore, an increase in ACTH synthesis would lead to an increase in glucocorticoid production.

B, C, and D are not correct because an increase in ACTH synthesis would not directly affect the release of CRH or cortisol, and there is no reason to expect a decrease in CRH release.
