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):
Submitted by Anonymous on. When an action potential reaches the end of one neurone there must be a way to start an action potential in the next neurone. The two neurons will not be in direct contact and action potentials cannot jump across the gap, called a synapse (or synaptic cleft), so another method is employed...s you can see above, the electrical impulse cannot cross the synaptic cleft, so a chemical called a neurotransmitter is released at the end of the first neurone out of the presynaptic membrane. It diffuses across the synapse, binds with the second neurone on the postsynaptic membrane and generates an action potential.
