The physiologic effects of the catecholamines are mediated by cell surface receptors on effector cells. E is the circulating hormone of the adrenal medulla, regulated by impulse traffic in the splanchnic nerves NE is the adrenergic neurotransmitter released from peripheral sympathetic nerve endings in response to a downward flow of impulses from the sympathetic centers in the brainstem and DA is formed in peripheral tissues from the decarboxylation of circulating DOPA. ![]() N2 - Norepinephrine (NE), epinephrine (E), and dopamine are the naturally occurring biologically important catecholamines. © 2018, Springer International Publishing AG, part of Springer Nature. ![]()
