The way that neurons communicate is through synaptic vesicles which release neurotransmitters.
<h3>What are Neurons?</h3>
The neurons are the basic structural and functional unit of the nervous system.
These neurons are able to communicate to each other through the neurotransmitters that are released by synaptic vesicles.
The neurotransmitters are chemical messengers that carry chemical signals from one neuron to another upon the generation of an action potential.
The synaptic vesicles are the organelles that house these neurotransmitters.
