The presence of leucine-enkephalin in the sacral preganglionic pathway to the urinary bladder of the cat.
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.
