Verified step by step guidance1
Understand that the body's stress response is primarily regulated by a physiological system that involves the brain and endocrine glands working together.
Recognize that the musculoskeletal, digestive, and reproductive systems have different primary functions unrelated to stress mediation.
Identify the hypothalamic-pituitary-adrenal (HPA) axis as the key system that coordinates the release of stress hormones like cortisol.
Recall that the HPA axis involves the hypothalamus signaling the pituitary gland, which in turn signals the adrenal glands to release hormones.
Conclude that the HPA axis is the primary physiological system mediating the body's stress response.
