    1) Something occurs to actually elicit an action potential - i.e. stabbing yourself with a thumbtack this stabbing generated action potential in certain nerve fibers in the skin.
    2) The membrane of these fibers possess a type of gated sodium channels that opens when the nerve ending is being stretched.
    3) Sodium permeable channels then open. ...

    Solution Summary

    The solution describes the process starting from the action potential to the release of the neurotransmitter.
