Effects of field stimulation on submucosal plexus in the isolated guinea pig ureter.
In a preparation consisting of the reversed ureter of the guinea pig, by field stimulation action potentials originating from nerve fibers and smooth muscle cells were recorded. The smooth muscle action potential was assumed to be due to excitation of the nerve fibers.
