NR546 Quiz reviews - Weekly Quiz review Propagation of an action potential to the axon terminal is mediated by voltage-sensitive sodium channels. Influx of sodium through voltage-sensitive sodium channels at the axon terminal leads to opening of voltage-sensitive calcium channels, also at the axon terminal. Influx of calcium through the open voltage sensitive calcium channels leads to docking of synaptic vesicles and secretion of neurotransmitter into the synapse.Agonists cause ligand-gate...
