Adrenaline is a catecholamine hormone, also known as epinephrine, secreted by the mammalian adrenal medulla as well as the adrenergic nerve endings. Its secretion is stimulated by the sympathetic nervous system under conditions of stress. Adrenaline stimulates blood flow to skeletal muscles and increases blood glucose levels. It also raises metabolic rate.
