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):
The neuromuscular junction is a well-studied example of a chemical synapse. Which of the following statements describes a critical event that occurs at the neuromuscular junction? a. When the action potential reaches the end of the axon terminal, voltage-gated sodium channels open and sodium ions diffuse into the terminal. b. Acetylcholine is released and moves across the synaptic cleft bound to a transport protein.
