And as they move from this orientation to this orientation, that opens, that widens that pore on this side of the membrane. And as soon as that pore widens, that creates the open state. And the sodium ions can basically move down their electrochemical gradient from a high outside concentration to a low inside concentration. So basically, this area is known as the depolarization period. And what that means is, because of the rapid opening of many of these voltage gated sodium ion channels, we have a rapid influx of these sodium ions into the cell. And so many of these positively charged sodium ions move into the cell.
