Action Potential Fire Threshold Bigger All Or Nothing Nature Reached

Action potentials are all-or-nothing; they fire at a fixed voltage once the threshold is met, with stronger stimuli increasing frequency rather than amplitude.

Action potentials follow an all-or-nothing principle: once the threshold is reached, they fire at a constant voltage; a stronger stimulus increases the firing frequency, not the amplitude.

Front Action potential All-or-Nothing nature
Back Once threshold has been reached, action potential always fire at same voltage

If threshold not reached then action potential not fire

Bigger stimulus not result in bigger action potential but increases the frequency at which they fire
