Action potential
| Name: | Action potential |
| Description: | A large, brief, all-or-nothing, regenerative electrical potential, that propagates along the axon, muscle fiber, or some dendrites. Action potentials are usually generated at the axon hillock and propagate uni-directionally down the axon. Adapted from Nicholls, Martin and Wallace 3rd edition. |
| Synonym(s): | Firing, Spike |
| Abbreviation: | AP |
| Super-category: | Membrane potential |
