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.
Adrenergic receptors respond to sympathetic stimulation and blood-borne epinephrine. Receptors are located on smooth muscle, cardiac pacemaker, myocardium and glands. Stimulatory subtypes are alpha 1 and beta 1; inhibitory subtypes are alpha 2, beta 2 &3. Adrenergic Receptors Adrenaline is the original name for what we now call epinephrine.
