If a neuron will not fire regardless of the amount of stimulation, it is most likely ____________?
Correct answer: B. in its absolute refractory period
- A. at its resting potential
- B. in its absolute refractory period
- C. an afferent neuron
- D. in its relative refractory period
Explanation
The absolute refractory period is the brief interval after an action potential when voltage-gated sodium channels cannot be reactivated, so no stimulus can produce another impulse. During the relative refractory period, an unusually strong stimulus can still trigger firing.
