adrenaline ( a ) and noradrenaline ( n ) release from the caudal mesenteric ganglion ( cmg ) during preganglionic nerve stimulation is due to acetylcholine action on n -- and m-cholinoreceptors of ganglion 's adrenergic structures ( gas ) and probably , primarily on sif -- cells , whereas during peripheral reflexes of cmg it is related to the excitation of noncholinergic afferent neurons which affect the corresponding receptors of gas .
