The nerve that supplies sensation to the cheek is a branch of which division of the trigeminal nerve?

The cheek’s sensation comes from a branch of the mandibular division of the trigeminal nerve. Specifically, the long buccal nerve (a sensory branch of V3) supplies the cheek skin and buccal mucosa. The ophthalmic division (V1) covers the forehead and supraorbital region, the maxillary division (V2) serves the midface (including parts of the cheek) but not via the buccal branch, and the facial nerve is a different system entirely, mainly motor to facial muscles. So the nerve that carries cheek sensation is a branch of the mandibular division.
