"Web(opening) of the channel allows sodium ions to move down their electrochemical gradient into the cell. This inward flow of sodium ions initiates the rising phase of the action potential (AP) and allows AP propagation. The activity of Na V is thus a crucial component of membrane excitability, and its loss leads to dysfunction in nerve and " - Opening of sodium gates typically leads to
