In the context of the neural impulse,which of the following is true about the depolarization of neuron membranes?
A)It is characterized by more negatively charged ions on the inside of the cell and more positively charged ions on the outside.
B)It decreases the charge difference between the fluids inside and outside of the neuron.
C)It is the brief wave of positive electrical charge that sweeps down the axon.
D)It is the phase that allows sodium ions to move out of the neuron.

Question

Quizplus · Accepted Answer

Depolarization is characterized by a rapid influx of positively charged ions, usually sodium ions, into the neuron, which reduces the charge difference between the fluids inside and outside of the cell, making the interior more positive. This change in the electrical charge triggers the neural impulse.
