And that means we have a longer depolarization period than normal than what we would see on a neuron. And this longer depolarization period is known as our plateau phase or plateau stage. So eventually the sodium channels or the calcium channels begin to close and our potassium channels begin to open quicker. And eventually we have this repolarization period and then we return to our normal resting membrane potential of negative 90 millivolts. Now, what is the function of this plateau phase? Why would we want a longer depolarization period?
