Regarding action potentials,which of the following statements is TRUE?
A)As the impulse travels along the axon,the movement of ions causes a change in charge from positive to neutral in successive sections of the axon.
B)The action potential moves from one end of the axon to the other like a flame moving along a fuse.
C)After the impulse has passed through a particular section of the axon,negative ions are pumped out of that section,and its charge returns to positive while the action potential continues to move along the axon.
D)Just after an action potential has passed through a section of the axon,a neuron can fire again immediately if it receives appropriate stimulation.

The action potential moves along the axon like a flame moving along a fuse. As the impulse travels along the axon, there is a change in charge from negative to positive in successive sections of the axon. After the impulse passes through a section of the axon, positive ions are pumped out of that section, and its charge returns to negative. It takes time for the axon to recover from an action potential, so a neuron cannot fire again immediately.
