During the absolute refractory period which of the following is true?
A) If a neuron reaches threshold,the action potential goes to completion.
B) The neuron fires at its maximum voltage if a stimulus depolarizes the neuron to threshold.
C) The signal grows weaker with distance.
D) It is possible to trigger a new action potential,but only with an unusually strong stimulus.
E) No stimulus of any strength will trigger a new action potential.

Question

Quizplus · Accepted Answer

During the absolute refractory period, the neuron is unable to generate a new action potential, regardless of the strength of the stimulus. This is because the voltage-gated sodium channels are inactivated and cannot open, which is necessary for depolarization and the initiation of a new action potential. Hence, option E is the correct choice.
