Action potential

An action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern.

There are four main stages to an action potential: depolarisation, repolarisation, hyperpolarisation, and the return to resting potential. Voltage-gated ion channels are needed for these processes.

Action potentials are brief, rapid, large changes in the membrane potential in which the potential actually reverses. They are usually initiated as a result of spread from graded potentials. Simil…
