Medical Definition of Trigeminal system
1.
Neurons associated with the fifth or trigeminal nerve, the largest cranial nerve.
The trigeminal system provides sensory innervation to the face and mucous membrane of the oral cavity, along with motor innervation to the muscles of mastication. It is called trigeminal because it has three major peripheral branches, the opthalmic, the maxillary and the mandibular nerves.
