A reflex
The difference between reflex and voluntary action is that a reflex occurs naturally in response to some sort of stimulus and voluntary action is something that is consciously carried out. An example of a reflex action is gagging and an example of voluntary action is flinching when someone is going to hit you.

An action by choice is a voluntary action.
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
National Center for Voluntary Action was created in 1970.
Voluntary Action History Society was created in 1991.
It is voluntary because your voluntary muscells in the arm are preforming this action.
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.
