Step 1: The Chemical Synapse An action potential arrives at the end bulb. Step 2: The Chemical Synapse Ca++ enters the presynaptic terminal. Step 3: The Chemical Synapse Ca++ interacts with the synaptic vesicle and fuses with the presynaptic membrane. Step 4: The Chemical Synapse Neurotransmitter is released and binds to the postsynaptic transmitter receptor. Step 5: The Chemical Synapse Receptor protein undergoes a change in shape that allows ions to flow. Step 6: The Chemical Synapse...
