1 RESTING STAGE The membrane is in polarised state with potential in nerve about 85mV Sodium and potassium channels are closed Na are more outside the cell K are concentrated inside the cell Potential difference 80mV 2 Depolarization STAGE When neurotrasmittr binds to the receptor ligand gated Na channels are open that causes local potential to touchthe threshold level 70 mV it opens up sodium channel in the membrane causing the abrupt rising of
