The trigeminal nerve is one of the twelve cranial nerves of the human being, to be precise the fifth.

Present in pairs (or pairs), the cranial nerves are fundamental nerve structures, which arise at the level of the brain and can have a sensory or motor function or both (therefore mixed).
The trigeminal nerve is a nerve with mixed functions, but with a prevalence of sensory fibers.
It originates at the level of the Varolio bridge (brain stem) and is divided, shortly after the point of emergence, into three large divisions (or branches): the ophthalmic nerve, the maxillary nerve and the mandibular nerve.
The ophthalmic nerve and the maxillary nerve play an exclusively sensory role, while the mandibular nerve has both sensory and motor nerve fibers.
The three divisions of the trigeminal nerve make three specific paths, along which they give rise to further branches.
