Nerv06/introduction/membrane potential
| In the resting membrane potential, inside the cell membrane is electrically negative, and outside positive. In the action potential, the polarity of the potential reverses. |
Even when the action potential is not being generated, there is a potential inside and outside the neuron membrane. This potential is called the 'resting membrane potential'. The largest difference between the resting and action potential is the electric polarity.
The potential of the resting membrane is about -80 mV, and that of action potential is about +20 mV. The membrane potential is generated by the difference in ion concentration inside and outside the membrane.
