Webb27 sep. 2010 · Slow waves serve to bring the membrane potential of smooth muscle cells to a threshold level that elicits a second electrical event known as the spike or action potential. The inward current of the spike, in most gastrointestinal smooth muscle preparations, is carried, at least in part, by calcium. WebbAt the peaks of the slow waves the membrane potential becomes sufficiently depolarized to initiate action potentials within GI smooth muscle cells. Thus, a recording of the smooth muscle cell membrane potential will display slow undulations with spikes of depolarization, representing action potentials, over-laying their gentle peaks.
