question 14
1 pts
the lumbar plexus gives rise to the _____ nerve.
median

femoral
none of the above is correct.

Explanation:

• Question 12: The cell bodies of the pre - ganglionic neurons of the autonomic nervous system are in the CNS (central nervous system), but the cell bodies of the post - ganglionic neurons are in the PNS (peripheral nervous system). So the statement “All cell bodies of the autonomic nervous system are located within the CNS” is false.
• Question 13: There are four ventricles in the brain: two lateral ventricles (one in each cerebral hemisphere), the third ventricle (in the diencephalon), and the fourth ventricle (between the pons/medulla oblongata and the cerebellum).
• Question 14: The lumbar plexus gives rise to the femoral nerve. The median nerve is from the brachial plexus, and the phrenic nerve is from the cervical plexus.

Answer:

• Question 12: B. False
• Question 13: C. four
• Question 14: C. femoral
