A specific threshold of stimulation is required to generate an action potential. If the threshold is reached, the action potential generated is always of the same magnitude, but stronger stimuli create more action potentials.
لإنشاء جهد فعل، يجب الوصول إلى عتبة تحفيز معينة. إذا تم الوصول إلى العتبة، فإن جهد الفعل المتكون يكون له نفس الحجم بغض النظر عن قوة التحفيز، ولكن التحفيز الأقوى يؤدي إلى زيادة عدد أجهزه الفعل.
| Front | threshold and size of stimuli effect on action pots |

| Back | certain level of stimuli needed for action pot to be created (threshold), if reached, action pot of same mag formed no matter size of stimuli, but stronger the stimuli, the more action pots created |
