while eating. He can chew food but has problems swallowing the chewed
pieces, and feels them in his throat. A radiographic study is performed
that shows normal musculature but abnormal esophageal peristalsis. No
masses are seen. Which of the following nerves should be tested for
abnormalities?
A. Hypoglossal and phrenic

1The correct answer is E. The upper 2/3 of the esophagus contains striated muscle. It is derived from the pharyngeal arches and innervated by the vagus nerve (CN X). The lower 1/3 contains smooth muscle from splanchnic mesoderm and is innervated by the splanchnic plexus.
The hypoglossal nerve (choices A and B), or CN XII, moves the tongue.
The phrenic nerve (choices A and D), derived from C3, C4, and C5, innervates the muscle of the diaphragm.
The glossopharyngeal nerve (choice C), or CN IX, functions in taste, swallowing, and salivation, as well as monitoring the activity of the carotid body
