D) They are the only places where two neurons touch.

Question

Quizplus · Accepted Answer

Vesicles are specialized organelles within neurons that store and release neurotransmitters in response to electrical signals. When an action potential reaches the axon terminal, it triggers the vesicles to release their neurotransmitter cargo into the synaptic cleft, where it can bind to receptors on the postsynaptic neuron. Vesicles are not responsible for the breakdown of used neurotransmitters, and they do not bind neurotransmitters released by axon terminals. Additionally, neurons can touch each other through other structures, such as gap junctions.
