THE ATROPINE‐RESISTANCE OF THE RESPONSE TO INTRINSIC NERVE STIMULATION OF THE GUINEA‐PIG BLADDER

Abstract

The urinary bladder responds to parasympathetic nerve stimulation by contraction but it has been shown in several species that this response is not blocked by atropine. Acetyl- choline applied to isolated bladder preparations, on the other hand, produces a contraction which is abolished by atropine in the manner characteristic of a muscarinic response.
