The neural impulse is along
the neuronal membrane
depolarization of consecutive
neighboring . When a region in
internal surface of the is
depolarized it becomes positive in
relation to neighboring internal
region. So electrical charges
(ions) move this more negative
region voltage-gated sodium
channels are and open. The
action then linearly propagates
along membrane until near the
region of the axon.
