Synaptic Transmission: A Four Step Process - Williams College
The process by which this information is communicated is called synaptic transmission and can be broken down into four steps. First, the neurotransmitter must be synthesized and stored in vesicles so that when an action potential arrives at the nerve ending, the cell is ready to pass it along to the next neuron.

The first step in synaptic transmission is the synthesis and storage of neurotransmitters. There are two broad categories of neurotransmitters. Small-molecule neurotransmitters are synthesized locally within the axon terminal.

Calcium Influx: Initiation of Neurotransmitter Release - Williams …
Most neurons contain at least two types of synaptic vesicles, small (about 50 nm diameter) and large (70-200 nm diameter). Neurotransmitters are released in quantal units as each vesicle contains a given amount of transmitter.

After release into the synaptic cleft, neurotransmitters interact with receptor proteins on the membrane of the postsynaptic cell, causing ionic channels on the membrane to either open or close. When these channels open, depolarization occurs, res ulting in the initiation of another action potential.
