The all-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is independent of the strength of the stimulus. If the stimulus exceeds the threshold potential, the nerve or muscle fiber will give a complete response; otherwise, there is no response. It was first established by the American physiologi...

noun (neurophysiology) a nerve impulse resulting from a weak stimulus is just as strong as a nerve impulse resulting from a strong stimulus
The rule that the size of the action potential is unaffected by increases in the intensity of stimulation beyond the threshold level.
the principle that under given conditions the response of a nerve or muscle fiber to a stimulus at any strength above the threshold is the same: the muscle or nerve responds completely or not at all.
States that neurons fire to generate an action potential only if stimulation reaches a minimum threshold.
