Question

Quizplus · Accepted Answer

The hypothalamic-pituitary-adrenocortical (HPA) axis involves the hypothalamus in the brain, which releases corticotrophin-releasing hormone (CRH), which then stimulates the pituitary gland to release adrenocorticotropic hormone (ACTH), which in turn stimulates the adrenal glands to release cortisol. Therefore, the structure involved in the HPA axis is the hypothalamus, not the hippocampus. Melatonin is not involved in the HPA axis.
