Fifth cranial nerve Definition from Encyclopedia Dictionaries & Glossaries
The trigeminal nerve (the fifth cranial nerve, also called the fifth nerve, or simply CNV or CN5) contains both sensory and motor fibers. It is responsible for sensation in the face and certain motor functions such as biting, chewing, and swallowing. Sensory information from the face and body is processed by parallel pathways in the central nervous system. The motor division of the trigeminal nerve is derived from the basal plate of the embryonic pons, while the sensory division originates from the cranial neural crest.
