Reaction
stimulus
The action potential is generated when a stimulus causes a change in the electrical potential across the cell membrane, resulting in the opening of voltage-gated ion channels. This allows an influx of sodium ions, causing depolarization of the membrane and initiation of the action potential.
reaction.
The all-or-none principle states that the properties of an action potential, such as amplitude and duration, are independent of the intensity of the stimulus that triggers it. This means that once a threshold stimulus is reached, the action potential will fire at maximal strength regardless of the strength of the initial stimulus.
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
The term you are looking for is "reaction" or "response." It describes the action taken as a result of a stimulus or influence.
No, the amplitude of an action potential is constant and does not vary with the strength of the stimulus. Instead, the frequency of action potentials fired by a neuron can increase with a stronger stimulus.
stimulus
Response is to stimuli as reaction is to trigger. A reaction is an action taken in response to a trigger or stimulus, showing a direct cause-and-effect relationship. Just as a response is elicited by a stimulus, a reaction is elicited by a trigger.
A reflex
An organism reacts to a stimulus with a response.
The action potential is generated when a stimulus causes a change in the electrical potential across the cell membrane, resulting in the opening of voltage-gated ion channels. This allows an influx of sodium ions, causing depolarization of the membrane and initiation of the action potential.

The FREQUENCY of action potentials that are conducted into the central nervous system serves as the code for the strength of the stimulus. This frequency code is needed because the amplitude of action potentials is constatnt (all or none). Acting through changes in action potential frequency, tonic receptors thus provide information about the relative intensity of a stimulus.
The all-or-none principle states that the properties of an action potential, such as amplitude and duration, are independent of the intensity of the stimulus that triggers it. This means that once a threshold stimulus is reached, the action potential will fire at maximal strength regardless of the strength of the initial stimulus.
A stimulus causes an action or response, like the ringing of your alarm clock if you didn't sleep through it.
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
