Events in Synaptic Signal Transmission

Events in Synaptic Signal Transmission

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

The sequence in which the events numbered above are involved in the signal transmission across the synapse is ____, ____, ____, _____,____,____,____.
