Neurotransmitters are released into the synaptic cleft. Neurotransmitters bind to ion channels. Sodium ions enter into the dendrites. Neurotransmitters are returned to the axon terminal, broken down by the enzymes or diffused away from the synapse. Action potential arrives in axon terminal. Synaptic vesicles containing the neurotransmitters fuse with the presynaptic membrane. Ion channels open. 

The sequence in which the events numbered above are involved in the signal transmission across the synapse is

The best way to see these steps is to google a pic of neuro synapse or find it in your text book. And just follow along with the steps.

1. Action potential reaches axon terminal

2. Vesicals holding neurotransmitters binds to presynaptic membrame, release neurotransmitters 

3. Neurotransmitters enter synaptic cleft. 

4. Neurotransmitters bind to ion channels on post synaptic membrane 

5. Ion channels open

6. Sodium enters dendrites. 

7. Neurotransmitter diffuse or broken down by enzymes.
