GlossaryHypothalamic-Pituitary-Adrenal Axis

regulates stress response through hormone release from brain and adrenal glands

The Hypothalamic-Pituitary-Adrenal (HPA) Axis is a complex network involving the hypothalamus, pituitary gland, and adrenal glands, which work together to regulate the body's response to stress. When you encounter stress, the hypothalamus releases corticotropin-releasing hormone (CRH), prompting the pituitary gland to secrete adrenocorticotropic hormone (ACTH), which in turn stimulates the adrenal glands to produce cortisol, a key stress hormone. This system plays a crucial role in maintaining homeostasis and can impact various bodily functions, including immune response and metabolism.
