Chapter 21
The reason that pain sensation in visceral organs is often associated with or “referred” to a
sensory surface of the body is most likely because
a. autonomic sensory fibers synapse upon the pain-sensitive second-order spinal
interneurons that receive somatic pain sensations.
b. the DRG neurons that sense peripheral pain have axon collaterals extending into the
viscera.
c. there are too few autonomic sensory fibers for us to distinguish surface pain from
deep pain.
d. there is no plausible biological mechanism that would allow pain to be associated
exclusively with our internal organs.
e. autonomic sensory fibers synapse upon the pain-sensitive nuclei in brainstem that
receive somatic pain sensations.
Which of the following would NOT be expected to result from sympathetic nervous system
activation?
a. Increased blood flow to certain muscles
b. Increased heart rate
c. Decreased blood flow to the GI tract
d. Increased uptake of glucose by the liver
e. Increased blood flow to the heart
