Leucine-enkephalin (L-ENK) nerve terminals which surround the cholinergic neurons in ganglia of the cat urinary bladder are eliminated after transection of the sacral ventral roots or the pelvic nerve. These findings, coupled with other anatomical and physiological data, suggest that L-ENK may be a cotransmitter with acetylcholine in the sacral preganglionic pathways to the urinary bladder.
在切断猫膀胱神经节中胆碱能神经元周围的亮氨酸脑啡肽（L-ENK）神经末梢后，骶腹根或盆神经被切断。这些发现，再加上其他解剖学和生理学数据，表明L-ENK可能是骶节前通路中与乙酰胆碱共同传递的神经递质。
