A stimulus strong enough to create an action potential
|
|
Submaximal Stimulus
|
|
|
Subthreshold Stimulus
|
|
|
Maximal Stimuli
|
|
|
Threshold Stimulus
|
Explanation:
Detailed explanation-1: -Subthreshold stimuli cannot cause an action potential. Threshold stimuli are of enough energy or potential to produce an action potential (nerve impulse). Suprathreshold stimuli also produce an action potential, but their strength is higher than the threshold stimuli.
Detailed explanation-2: -When the intensity of the stimulus is increased, the size of the action potential does not become larger. Rather, the frequency or the number of action potentials increases.
