Quizplus · Accepted Answer

The typical threshold for an action potential is around 5-10mV of depolarization. Once the neuron reaches this threshold, it will generate an action potential and send signals down its axon. Choices A and B are too low, and D is too high, as it would require significant depolarization for the neuron to reach that level.
