Answer 1

Answer: The cranial nerve responsible for pain in her upper right molar (C) the facial trigeminal nerve.

Explanation:

Cranial Nerves are a set of 12 nerves that originate directly from the brain and exit it through holes called cranial foramina, at the base of the brain rather than exiting through the spinal cord. These nerves are rsponsible for transmitting information from the brain to head and neck regions of the boday and vice versa.

The facial and the trigeminal cranial nerves are responsible for facial movement and taste and for face sensation and chewing, respectively.

The trigeminal nerve is the largest of all the cranial nerves. It has three branches: ophthalmic, mandibular and maxillary nerves.
