WebbThe sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na + and K + at constant disequilibrium. The sudden shift from a resting to an active state, when the neuron generates a nerve impulse, is caused by a sudden movement of ions across the membrane—specifically, a flux of Na + into the cell.
