The trigeminal nerve (cranial nerve V) primarily conveys sensory impulses from the facial region, anterior scalp, mucous membranes of the mouth, nose, and the anterior two-thirds of the tongue (except for taste). It also has motor functions related to mastication but does not control eye movements or pupil constriction, which are functions of other cranial nerves.
