Trigeminal Nerve: “The trigeminal nerve is the fifth and largest cranial nerve, responsible for providing sensation to the face and controlling chewing muscles. It has three main branches—the ophthalmic (V1), maxillary (V2), and mandibular (V3)—which transmit feelings like touch, pain, and temperature from different areas of the face and mouth to the brain.
❄️Branches and their functions❄️
✔️Ophthalmic nerve (V1): This branch provides sensation to the forehead, the eye, the upper eyelid, and the nose.
✔️Maxillary nerve (V2): This branch provides sensation for the middle of the face, including the cheek, upper teeth and gums, lower eyelid, and the side of the nose.
✔️Mandibular nerve (V3): This branch provides sensation to the lower part of the face, including the jaw, lower teeth and gums, and lower lip. It also contains motor fibers that control the muscles used for chewing.”
