The brief wave of positive electrical charge that sweeps down the axon is
A)resting potential.
B)action potential.
C)graded potential.
D)polarized potential.

Question

Quizplus · Accepted Answer

The brief wave of positive electrical charge that sweeps down the axon is the action potential. This occurs when the threshold is reached, causing voltage-gated ion channels to open and allowing an influx of positive ions, resulting in depolarization and the propagation of the electrical signal down the axon.
