What is the role of epinephrine during the stress response?

William B. Salt II., MD
Gastroenterology
The epinephrine pathway of your stress response system activates within seconds, when the sympathetic branches of the autonomic nervous system carry the alarm signal from the hypothalamus of the limbic system to the adrenal medulla (the inner portion of the adrenal gland), which releases epinephrine. Epinephrine is one of two catecholamines released by the activation of the sympathetic nervous system. The other is norepinephrine. Epinephrine prepares the body for quick action. Blood flow shifts from the skin and digestive tract to the muscles, your heart rate increases, your blood pressure rises and you become more alert.
