During an action potential, the electrical charge inside the neuron is _________ compared to the electrical charge outside the neuron
A) positive
B) balanced
C) negative
D) neutral
Answer: A
Rationale: During an action potential, a wave of electrical activity originates at the base of the axon and rapidly travels down its length. The action potential moves down the length of the axon as positively charged ions rush through the membrane pores. During the action potential the net charge of the cell goes from negatively to positively charged.
