Synaptic neurotransmission PROCESS

1 Action Potential arrives at axon terminal 2 Voltage gated Ca2+ channels open 3 Ca2+ enters the presynaptic neurons 4 Ca2+ signals to neurotransmitter vesicles 5 Vesicles move to the membrane and dock 6 Neurotransmitters released via exocytosis 7 Neurotransmitters bind to receptors 8 Signal initiated in postsynaptic cell
