When an action potential reaches the end of the axon terminal, it:
A) reverses direction and returns to the cell body.
B) causes synaptic vesicles to break open and release molecules of neurotransmitter.
C) causes pores on the axon terminal to open and receive neurotransmitters from other neurons.
D) hops across the synaptic cleft to the next neuron.

Question

When an action potential reaches the end of the axon terminal, it causes synaptic vesicles to break open and release molecules of neurotransmitter. These neurotransmitters then travel across the synaptic cleft to bind to receptors on the next neuron, allowing for neural communication to occur.
