A rapid change in the membrane potential of excitable cells such as neurons and muscles; this usually involves a steep rise (depolarization) followed by a steep fall in membrane potential (repolarization). The cell subsequently enters a short refractory period (hyperpolarized state) during which it cannot generate another action potential.

What is the difference between a graded potential and an action potential?
Graded potentials are initiated by a stimulus that vary in magnitude depending on the strength of the stimulus. (The stronger the stimulus the more gated channels open causing larger depolarisation) …
