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 junction between the axon terminals of a neuron and the receiving cell is called a synapse. (Synapses at muscle fibers are also called neuromuscular junctions or myoneural junctions 1  .). Action potentials travel down the axon of the neuron to its end(s), the axon terminal(s).he neurotransmitter at inhibitory synapses hyperpolarizes the postsynaptic membrane. The GABA A receptor is a ligand-gated chloride channel. Binding of GABA to the receptors increases the influx of chloride (Cl â) ions into the postsynaptic cell raising its membrane potential and thus inhibiting it.
