Which of the following sequences is correct?
A) corticotropin-releasing hormone (CRH),adrenocorticotropic-releasing hormone (ACTH),adrenal medulla
B) adrenocorticotropic-releasing hormone (ACTH),corticotropin-releasing hormone (CRH),adrenal medulla
C) corticotropin-releasing hormone (CRH),adrenocorticotropic-releasing hormone (ACTH),adrenal cortex
D) adrenocorticotropic-releasing hormone (ACTH),corticotropin-releasing hormone (CRH),adrenal cortex

Question

Quizplus · Accepted Answer

CRH stimulates the release of ACTH, which in turn stimulates the adrenal cortex to produce and release cortisol. The adrenal medulla is not involved in this pathway as it primarily secretes epinephrine and norepinephrine in response to sympathetic nervous system activation. Therefore, options A and B are incorrect. Option D has the order of CRH and ACTH reversed, making it incorrect. Option C has the correct order of CRH stimulating the release of ACTH, which then acts on the adrenal cortex to produce cortisol.
