During an action potential,what changes are evident in the negative ions inside the neuron?
A)Negative ions rush out of the axon to increase the positive charge inside the axon.
B)Negative and positive ions flow into the axon to maintain a balanced proportion.
C)There is little or no net change in the distribution of negative ions.
D)Negative ions trigger the release of neurotransmitters in the axon terminals.

During an action potential, there is little to no net change in the distribution of negative ions inside the neuron. This is because the action potential is generated by a brief influx of positive ions, specifically sodium ions, which depolarizes the cell membrane and creates an electrical gradient. The negative ions, such as chloride and potassium, remain inside the cell and are involved in the repolarization phase of the action potential.
