  2. 5. Certain level of membrane potential to be surpassed
  3. 6. Neurotransmitter that transmits signals to skeletal muscles
  4. 7. "Downtime" after an action potential when a second action potential cannot be initiated
  5. 8. Neuronal process that transmits the action potential
  6. 9. Sodium channels close and potassium channels open causing this
  7. 12. Lipid that insulates the axon
