Action potential Action potential is caused by temporary changes in membrane permeability for diffusible ions. The influx and expulsion of ions within the cell cause an action potential. Depolarisation, overshoot or peak phase, repolarisation, and refractory period are the phases of an action potential. In this context, “potential” refers to an electric potential rather than the likelihood of achieving anything. Action potential is different from graded potential.

This article is about the action potential, which is a sudden, fast, transitory and propagating change of the resting membrane potential. It discusses its definition, phases (depolarization, overshoot and repolarization), refractory period, propagation of action potential along an axon to reach the terminal button … See more
