尿管の活動電流について

抄録

The action potential of the ureter was detected by the oscillograph of cathode ray type or of electromagnetic type. It was elucidated that the action potential consists of three phases, i, e. weak positive, strong negative and again weak positive. “All or none law” was found to be valid for the action potential evoked by the stimulation in the ureter The conduction velocity of the action potential was 10 mm/sec. The direction of the volley propagated in the ureter was demonstrated having no effect on the wave from of the action potential or on its conduction velocity.
The relation between the response time of the action potential and the voltage of the stimulating current was hyperbolic.
