Question
Chapter 21.3, Problem 10CC
Summary Introduction
To determine: The type of control which includes parasympathetic excitation and sympathetic inhibition of GI function.
Introduction: Gastrointestinal tract (GI) is a series of organs joined together. It starts at the mouth and ends at the anus. These organs together form the

Describe the effect of sympathetic innervation on each effector organ, especially the heart, blood vessels, gastrointestinal tract, lungs, adrenal medulla, and external genitalia.
Describe the sympathetic vasomotor tone: its origin, the neurotransmitter and receptor responsible for the effect. What is the physiological significance of the sympathetic tone?
In the sympathetic division of the autonomic
nervous system:
Select one:
The ratio between the number of
postganglionic and preganglionic neurons
is small.
A single preganglionic neuron usually
synapses with a single postganglionic
neuron.
An important functional characteristic is
convergence of the preganglionic fibers.
Preganglionic fibers are usually much longer
than the postganglionic fibers.
Activity of the neurons tends to have a more
generalized and widespread effect on the
body.
