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.
NE can also bind to Î± 1-adrenoceptors found on myocytes to produce small increases in inotropy. Circulating catecholamines (epinephrine) released by the adrenal medulla also bind to these same alpha and beta adrenoceptors in the heart. In addition to sympathetic adrenergic nerves, the heart is innervated by parasympathetic cholinergic nerves derived from the vagus nerves.
