What Causes The Voltage-gated Na Channels To Open?

What Causes The Voltage-gated Na Channels To Open? All the voltage-gated Sodium channels open when the membrane potential reaches around -55 mV and there’s a large influx of Sodium, causing a sharp rise in voltage. … The depolarization of the cell stops and repolarisation can occur through these voltage-gated Potassium channels. What could causes a
