... The cell remains at resting potential until a stimulus reaches the cell, either from another neuron or the environment. Channels in the membrane open to allow Na+ ions to enter the cell. The inside of the cell temporarily becomes more positive. This is called the action potential. Refer to fig. 35-7 ...
