The mandibular division of the trigeminal nerve is:

The mandibular division of the trigeminal nerve is:

• A. Motor and Sensory
• B. Sensory
• C. Motor
• D. Both

Answer: (A)

The mandibular division is a mixed branch of the trigeminal nerve, meaning it carries both sensory and motor fibers. It provides sensory input from the lower face, lower teeth, mucosa of the mouth, and parts of the tongue, as well as motor output to the muscles of mastication (masseter, temporalis, and the medial and lateral pterygoids) plus a few other muscles like the mylohyoid and certain tensor muscles. This combination of senses from the lower face and the motor control of chewing muscles distinguishes it from the other divisions, which are purely sensory.
