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):
The axons are analog to digital converters and transmitters. The axon initial segment produces a digital action potential (spike) when the summation of the voltages within the neuron are above a threshold. The action potential is a one-tenth of a volt electrical signal that travels down an axon at speeds up to about 100 meters per second. Myelin sheaths cover many axons; this increases the speed a signal can travel down an axon. The myelinated axons make up the white matter of the brain.
