The hypothalamus, pituitary gland, and adrenal glands make up the hypothalamic-pituitary-adrenal (HPA) axis, which plays a pivotal role in triggering the stress response. By releasing certain chemicals, such as adrenocorticotropic hormone (ACTH) and cortisol, the HPA axis rouses the body for action when it's faced with a stressor.
