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):
Confidence votes 60. Muscle contraction in initiated by an action potential sent from the brain or spinal cord to the axon terminal of a motor neuron. Calcium then goes into the axon terminal which causes the release of the neurotransmitter acetylcholine which binds to receptors on the plasmalemma.uscle contraction in initiated by an action potential sent from the brain or spinal cord to the axon terminal of a motor neuron.
