nonadrenergic noncholinergic

nonadrenergic noncholinergic (NANC) neuron (nnˈ·a·dr·nurˑ·jik nnˑ·kō·li·nurˑ·jik),

n an autonomic, efferent nerve cell, the method of transmission of which is not based upon adrenergic (e.g., epinephrine, dopamine) or cholinergic (i.e., acetylcholine) neurotransmitters.

Various adrenergic, cholinergic, and nonadrenergic noncholinergic neurotrans-mitters released from nerve terminals and endogenous factors released from vascular endothelial sources are responsible for the smooth muscle tone in the lower urinary tract (LUT).
8,9,11,16) Although the abnormalities of enteric nerves, including adrenergic, cholinergic, nonadrenergic noncholinergic (peptidergic), and nitrergic nerves, have been suggested to be the cause of bowel dysfunction in this condition, the exact pathogenesis of HD is not fully understood.
Since the dense reticular network of ICCs intimately surrounds the nitrergic neuronal plexus and demonstrates abundant gap junctions connected with smooth muscle cells and nerve fibers, it is very likely that these cells play a role as a mediator in neurotransmission, possibly the nonadrenergic noncholinergic inhibition.
