Resting potential
The membrane potential of a neuron at rest. The inflow and outflow of ions are in equilibrium. It ranges from –50 to –100 mV.

Threshold potential
In order for an action potential to be triggered, the membrane potential at the axon hillock of a neuron must exceed the threshold value of approximately –50 mV (relative to the resting potential of –70 mV). This is the threshold potential. If the depolarization remains below this threshold, no action potential is triggered.

Depolarization
The decrease in membrane potential (towards 0 mV) from the resting potential, which is measured between the inside of the cell and the outside space and has a difference of -70 mV.
