Give the sequence of events involved in transmission at a chemical synapse.
1. Action Potential invades presynaptic terminal
2. Depolarization causes voltage-gated Ca2+ channels to open.
3. Rapid influx of Ca2+ into the cell
4. Ca2+ causes synaptic vesicles to fuse with the presynaptic membrane
5. Neurotransmitter is released into synaptic cleft via exocytosis.
6. Neurotransmitter binds to specific receptors in postsynaptic membrane.
7. Opening (or closing) of ion channels. So ions can diffuse
