WebThe nonadrenergic noncholinergic (NANC) nerves are modulators of the pulmonary circulation that are not inhibited by adrenergic or cholinergic blockade. 96 The response of the pulmonary circulation to NANC input can be either vasodilation or constriction. Several putative transmitters mediate the NANC neural response in the pulmonary circulation.
