Before receiving a nerve impulse, a neuron is at its resting potential, with more negative charges inside the cell than on the outside of the cell. When the neuron receives the nerve impulse, it is depolarized, allowing positive ions to flow across the cell membrane into the neuron. This is called an action potential, and the action potential travels the length of the neuron, taking advantage of the myelin sheath on many neurons. Once the signal has traveled through the neuron, the sodium-potassium pump repolarizes the cell, restoring the resting potential of the neuron.
