Name the two divisions of the autonomic nervous system (ANS). Briefly describe the general physiological roles of each. Which one is sometimes called the ‘rest and digest’ system? Which one is call the ‘fight or flight’ system? Explain why each have these names.
1. Name the two divisions of the autonomic nervous system (ANS). Briefly describe the general
physiological roles of each. Which one is sometimes called the ‘rest and
call the ‘fight or flight’ system? Explain why each have these names.
2. Compare and contrast the basic anatomy of the parasympathetic and sympathetic systems, including
central nervous system locations, ganglia locations, pre- and post-ganglionic neuron relative lengths,
and ganglionic and effector neurotransmitters.
3. List and describe the major effects of sympathetic stimulation on the major organs. Describe the
difference between an adrenergic receptor and a cholinergic receptor. List the adrenergic receptor
types, and name where you would find them. State their primary function.
4. List and describe the major effects of parasympathetic stimulation. Explain why sympathetic effects
tend to be systemic and long lasting, while parasympathetic effects are local and short lived.
5. Describe examples of specific effectors dually innervated by the two branches of the autonomic nervous
system and explain how each branch influences function in a given effector.
