Question

if a neuron is immediately stimulated right after an action potential, what is likely to happen?
o a. nothing will happen because of the \all - or - none\ principle.
o b. nothing will happen because of the refractory period.
o c. another action potential will fire.
o d. overstimulation will result in inflammation.

Explanation:

After an action potential, a neuron enters a refractory period during which it cannot fire another action potential. The all - or - none principle relates to the nature of an action potential once it starts, not to what happens immediately after. Overstimulation leading to inflammation is not relevant to what occurs right after an action potential at the single - neuron level.

Answer:

B. Nothing will happen because of the refractory period.
