Where are the parasympathetic ganglia located? -
Answer-In or near effector organs
In general, what are the functions of the sympathetic and
the parasympathetic divisions of the autonomic nervous
system? - Answer-Sympathetic: Fight or flight response,
prepare for emergency/stress/exercise, increase heart rate
and blood pressure, mobilize energy stores, pupillary
