Witryna18 gru 2016 · When the electrical impulse travels down the nerve and hits these channels, they open. This flow of ions reestablishes the electrical signal and keeps it traveling down the cell membrane. Certain ion channels are mechanically-gated, meaning they open when the plasma membrane physically moves.
