The tenth cranial nerve is also known as which nerve?

• A. Tenth cranial nerve
• B. Fifth cranial nerve
• C. Seventh cranial nerve
• D. Ninth cranial nerve

Answer: (A)

The main concept here is knowing the common name j used for the tenth cranial nerve. The tenth cranial nerve is the vagus nerve. It’s a major nerve with widespread parasympathetic roles, supplying much of the thoracic and abdominal organs and helping regulate heart rate, digestion, and other autonomic functions. The other nerves referenced correspond to different cranial nerves: the trigeminal nerve handles facial sensation and chewing, the facial nerve controls muscles of facial expression and some taste, and the glossopharyngeal nerve is involved in taste and swallowing. So the nerve commonly known by its name for the tenth position is the vagus nerve.
