All-or-nothing principle
According to this principle, an electrical potential is only triggered in the cell when a certain threshold value of stimulus intensity has been exceeded. The response either occurs completely or not at all.

Action potential
In excitable cells (e.g., neurons or muscle cells), very rapid changes in electrical potential occur across the cell membrane. This event is the basis for signal conduction along the axon of the nerve cell. The action potential continues along the cell membrane and, according to the all-or-nothing principle, only occurs when the cell has been sufficiently excited.
