The Autonomic Nervous System (ANS)

1. Compare the autonomic nervous system with other areas of the nervous system. 
2. Contrast the structures and functions of the sympathetic and parasympathetic divisions of the ANS. 
3. Describe the mechanisms of neurotransmitter release in the ANS. 
4. Compare the effects of the various autonomic neurotransmitters on target organs and tissues. 
5. Discuss the relationship between the two divisions of the ANS and the significance of dual innervation. 
6. Explain the importance of autonomic tone. 
7. Describe the hierarchy of interacting levels of control in the ANS.

You will receive an index card with either an Autonomic Event or a Reaction described on it.  You must find the index card which contains the Autonomic Event or Reaction that matches your index card.  Be sure to compare all potential partners as some events may have more than one reaction.  

  Each autonomic event and reaction should be paired up. 

Part B 

Once all events and reactions are paired -- you and your partner will prepare an illustration that details the following: 

1. the division of the ANS responsible for the event and reaction;  
2. the anatomical pathway of the event and reaction;  
3. the neurotransmitters released to cause the reaction; and the interaction of the ANS which interacts to control this event from occurring constantly. 

  A poster describing the event and reaction as identified above.
