Why do Na+ ions enter the cell when voltage-gated Na+ channels are opened in neurons?

#Unit 7. System Physiology – Animal

because the Na+ concentration is much lower outside the cell than it is inside
because the Na+ ions are actively transported by the sodium-potassium pump into the cell
because the Na+ concentration is much higher outside the cell than it is inside, and the Na+ ions are attracted to the negatively charged interior
because the Na+ concentration is much higher outside the cell than it is inside, and the Na+ ions are actively transported by the sodium-potassium pump into the cell
