Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best describes action potentials?
A
The movement of negatively charged ions into the neuron cell after a stimulus of any size.
B
Electrical impulses produced by the body that are stronger when the stimulus is bigger.
C
Uniform in strength and speed but frequency varies depending on the stimulus.
D
This is how you feel in the morning based on your energy level of what you “potentially” can do during the day.
Explanation: 

Detailed explanation-1: -Answer and Explanation: The correct answer is d. An action potential is an all-or-nothing event.

Detailed explanation-2: -If the stimulus is prolonged there will be a greater frequency of action potentials on one neuron. With an intense and prolonged stimulus, the frequency of action potentials on many neurons will increase. This can be understood as a greater number of simultaneous action potentials.

Detailed explanation-3: -There is a maximum frequency at which a single neuron can send action potentials, and this is determined by its refractory periods.
