  5. #4 Match the following neurotransmitters with their descriptions: • Body’s natural pain killer • Helps regulate mood • Involved in pleasurable experiences • Dopamine • Norepinephrine • Acetylcholine • Endorphines

  6. #5 During an action potential the inside of an axon has a ___________ charge due to the influx of __________ ions.

  7. #6 Two part question: • Name the 3 divisions of the peripheral nervous system. • Which PNS division contains the sympathetic and parasympathetic divisions?

  8. #7 Which part of a neuron first receives neurotransmitters and then creates an impulse?

  9. #8 Label the objects of the neuron below: Choices: Neurotransmitters Impulse Plasma membrane Vesicle Schwann cell Synapse Receptor
