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. / \. F F Because the octahedral geometry is symmetrical, the bond dipoles cancel, and the molecule is nonpolar, meaning that Âµ = 0.Source: Straight from Chemistry: The Central Science. 11e. \.

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):
Within the axon terminal are many small vesicles containing a neurotransmitter substance called ____. 18. Nerve impulse. When the ______ reaches the ends of the axon, the neurotransmitter is released and diffuses to to the muscle cell membrane to combine with receptors there.19.8. Nerve impulse. When the ______ reaches the ends of the axon, the neurotransmitter is released and diffuses to to the muscle cell membrane to combine with receptors there.
