From which division of the trigeminal nerve do the TMJ-innervating nerves originate?

Explanation:
TMJ sensation comes from the mandibular division of the trigeminal nerve. The auriculotemporal nerve, a branch of this division, travels around the joint capsule and carries the sensory fibers that transmit pain and other sensations from the TMJ. This makes V3 the source of TMJ innervation, not the other trigeminal divisions. The ophthalmic division (V1) serves areas like the forehead and eye region, the maxillary division (V2) supplies the midface, and the facial nerve is a separate cranial nerve (VII) that mainly handles facial expression muscles, not joint sensation.
