What function is associated with the trigeminal nerve?

• A. Tongue movement
• B. Chewing and facial sensation
• C. Swallowing and voice
• D. Shoulder and head movement

Answer: (B)

The trigeminal nerve, known as cranial nerve V, is primarily responsible for providing sensory innervation to the face and motor functions for mastication (chewing). This nerve has three major branches: the ophthalmic, maxillary, and mandibular nerves, which collectively facilitate facial sensation, allowing us to feel touch, pain, and temperature on the face. Additionally, the mandibular branch of the trigeminal nerve innervates the muscles involved in chewing, making it essential for the motor function of mastication. This multifaceted role in both sensory perception and motor function directly relates to the correct choice regarding its associated functions.
