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.

Vesicles at the end of the axon release neurotransmitters which float across the synaptic cleft to the next neuron. This process is called synaptic transmission. The neurotransmitters bind to receptors on the dendrites or cell body of the next neuron, creating a postsynaptic potential that can either depolarize or hyperpolarize the neuron, potentially leading to the generation of a new action potential.
