Quizplus · Accepted Answer

The correct three structures involved in the HPA axis are the hypothalamus, pituitary gland, and adrenal glands. The hypothalamus releases corticotropin-releasing hormone (CRH), which signals the pituitary gland to release adrenocorticotropic hormone (ACTH). ACTH then signals the adrenal glands to release cortisol. This axis is important in the body's stress response and regulation of many physiological processes.
