An action potential begins when a stimulus depolarizes the axon membrane to approximately -55mV. This is the threshold potential for opening the activation gates in many of the nearby voltage-gated Na + channels. As a result, positively charged Na + ions begin to move along their concentration gradient and enter an axon. …
