Neurons Communicate by Neurotransmission
... Instead, that electrical signal triggers chemical changes that can cross the synapse and affect the postsynaptic cell. When the electrical impulse reaches the presynaptic axon terminal, it causes membranous sacs, called vesicles, to move toward the membrane of the axon terminal. When the vesicles re ...
