The fusion of the vesicular membrane with the axonal membrane begins when ___cacium__ enter the cell through ____propagation of an action potential to the presynaptic membrane______, resulting in __________temporary ion chain nurotransmitters
When an action potential arrives at an axon terminal, it causes the opening of calcium channels, which triggers fusion of neurotransmitter vesicles with the cell membrane
