Quizplus · Accepted Answer

When a neuron is polarized, the inside of the cell has a more negative charge than the outside. This is maintained by the presence of ion channels in the cell membrane that control the movement of ions in and out of the cell. When a neuron is depolarized, the membrane potential becomes less negative, which can lead to the firing of an action potential.
