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):
â¢ The neuromuscular junction is the place where the terminal portion of a motor neuron axon meets a. muscle cell membrane, separated by a synaptic cleft. â¢ An action potential arriving at the axon terminal brings about the release of acetylcholine, which. leads to depolarization of the motor end plate.elease of Acetylcholine. â¢ Acetylcholine is released into the synaptic cleft & calcium ions are pumped out of the axon terminal. ** During the animation note that in addition to the acetylcholine going into the synaptic cleft (blue), calcium ions also move out of the axon terminal (red).
