Which is NOT a main branch of the trifacial nerve?

Ophthalmic
Maxillary
Mandibular
Nasal

The correct answer is: Nasal

The trigeminal nerve is an important cranial nerve responsible for providing sensation and movement to the face. It has three main branches, the ophthalmic nerve, the maxillary nerve, and the mandibular nerve. These three branches innervate different areas of the face, including the forehead, cheek, and jaw. The nasal branch, on the other hand, is not a main branch of the trigeminal nerve. It is a smaller branch that branches off of the ophthalmic nerve and provides sensation to the tip of the nose. Therefore, the nasal branch is not considered one of the main branches of the trigeminal nerve.
