Action potentialis the maximum
voltage level achieved by
neuron in the process neuronal
activation, around + mV. The action
potential the depolarization of
the regions of the plasma
and thus the propagation
the impulse along the .

Resting potential is the
voltage when the cell not excited,
about –70 .

Excitation threshold is the level,
about –50 mV, the initial
depolarization must for the action
potential be attained.
