Once an Action Potential Reaches the End of the Axon

Multiple Choice

Once an action potential reaches the end of the axon, how does the information usually get to the next neuron?

A) The action potential jumps across the synaptic cleft to the next neuron in the form of an electrical impulse.
B) Myelin acts as a bridge to transport it across the synaptic cleft.
C) Potassium ions (K+) move back and forth between neurons to carry the information across.
D) Vesicles at the end of the axon release neurotransmitters which float across the synaptic cleft to the next neuron.
