During the passage of a nerve impulse, sodium ions pass through gated channels (A), positive feedback causes more sodium ions to enter the cell (B), the interior of the cell becomes positive relative to the outside (C), and changing voltage increases the number of open gates (D). Therefore, all of these occur (E).
