WebAug 12, 2024 · Once a graded or action potential (but mostly action) moves into the neuron, it triggers the neuron to permit access to free-floating calcium ions. The process behind the influx of calcium ions is the electrical depolarization of the membrane (at the synapse). These calcium ions trigger the vesicles to fuse against the axon terminal’s membrane. graphic frog foggia
