Binding of Epinephrine to Adrenergic Receptors Induces Tissue-Specific Responses. Epinephrine and norepinephrine were originally recognized as products of the medulla, or core, of the adrenal gland and are also known as adrenaline and noradrenaline.
Beta blockers block the action of endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) -in particular on adrenergic beta receptors, of the sympathetic nervous system, which mediates the fight-or-flight response.hree types of beta receptors are known, designated Î² 1, Î² 2 and Î² 3 receptors. Î²1-adrenergic receptors are located mainly in the heart and in the kidneys. Î²2-adrenergic receptors are located mainly in the lungs, gastrointestinal tract, liver, uterus, vascular smooth muscle, and skeletal muscle.
