WebCholinergic blockers usually inhibit cholinergic nerve transmission at the neuroeffector junction, or the point where the nerve ending reaches the effector organs such as smooth muscle, cardiac muscle, and glands. Cholinergic blockers have little effect at the nicotinic receptors, although at high doses they can have partial blocking effects.

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. Webcholinergic 1.
