By stimulating the adrenal cortex, ACTH leads most directly to the release of which hormone?

Question

Quizplus · Accepted Answer

ACTH stimulates the adrenal cortex to release cortisol, which is a glucocorticoid hormone involved in stress response, metabolism regulation, and immune function. Noradrenaline and adrenaline are released from the adrenal medulla in response to sympathetic nervous system stimulation, which is not directly regulated by ACTH. Testosterone is synthesized in the testes (in males) and adrenal glands (in both males and females), but its release is not directly regulated by ACTH. Somatostatin is a hormone that inhibits the release of other hormones like growth hormone and insulin, but it is not involved in the adrenal cortex's response to ACTH.
