WebbThe slow waves usually do not by themselves cause muscle contraction in most parts of the gastrointesti-nal tract, except perhaps in the stomach. Instead, they mainly excite the appearance of intermittent spike potentials, and the spike potentials in turn actually excite the muscle contraction. Spike Potentials.
