Verified step by step guidance1
Understand that cortisol is a steroid hormone that plays a role in the body's stress response.
Recognize that the hypothalamus, pituitary gland, and adrenal glands are part of the hypothalamic-pituitary-adrenal (HPA) axis, which regulates stress responses.
Identify that the hypothalamus releases corticotropin-releasing hormone (CRH) to signal the pituitary gland.
The pituitary gland then secretes adrenocorticotropic hormone (ACTH) in response to CRH.
Finally, ACTH stimulates the adrenal cortex, which is the outer part of the adrenal glands, to release cortisol into the bloodstream.
