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¢ Calcium ions trigger a contraction of the muscle cell. Summary. â¢ Each skeletal muscle cell is individually stimulated by a motor neuron. 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.â¢ Depolarization of the motor end plate triggers an action potential that propagates along the sarcolemma and down the T Tubules.â¢ This action potential causes the release of calcium ions from the terminal cisternae into the cytosol, triggering contraction of the muscle cell. An action potential arriving at the axon terminal brings about the release of acetylcholine, which leads to depolarization of the motor end plate. â¢ Depolarization of the motor end plate triggers an action potential that propagates along the sarcolemma and down the T Tubules.
