Why: Fluorine is more electronegative than sulfur, so the bond dipoles point toward fluorine. The six S-F bonds are arranged octahedrally around the central sulfur.F F. \ /. F-S-F. / \.

Best Answer: It causes none of those. When the action potential reaches the axon terminal, it causes the vesicle sacs to release neurotransmitters into the synapse. The neurotransmitters float across the synapse to the dendrite of the postsynaptic cell. Source(s):
4. At the axon or presynaptic terminal, the action potentials open voltage-gated calcium channels to open, allowing calcium to enter the cell. This leads to the release of the neurotransmitters from the terminal into the synaptic cleft (space between the presynaptic and postsynaptic neuron).
