'typically' chemical synaptic transmission takes place when an influx of calcium ions during a presynaptic nerve impulse triggers exocytosis of neurotransmitter substance from synaptic vesicles. Located at the end of each telodendrion.
Which Of These Ions Triggers Exocytosis Of Synaptic Vesicles. �typically� chemical synaptic transmission takes place when an influx of calcium ions during a presynaptic nerve impulse triggers exocytosis of neurotransmitter substance from synaptic vesicles. It contains synaptic vesicles with neurotransmitters that send messages to the axon�s target. Ca ions bind to a complex of proteins responsible for the exocytosis of synaptic vesicles the neurotransmitter will have no effect in the postsynaptic cell what happens if a drug inhibits neurotransmitter receptors on the postsynaptic cell? These two papers [40 ,41 ] demonstrate that synaptotagmin, a synaptic vesicle protein considered to be a likely candidate for the ca2+ sensor of synaptic exocytosis, is also important for membrane retrieval and vesicle recycling following exocytosis.

As mentioned above, exocytosis of synaptic vesicles preferentially occurs at the base of the synaptic ribbon (zenisek et al., 2000; One of the proteins that has a crucial role in this secretion event is synaptotagmin i, an abundant constituent of synaptic vesicles that binds ca2+ ions through two c2 domains. This fundamental mechanism was discovered in pioneering work on the neuromuscular junction by katz and miledi (1967).
