mesencephalic tract of the trigeminal nerve

An axon tract of the unipolar sensory neurons of the trigeminal mesencephalic nucleus. Peripheral processes of these neurons run in the mesencephalic tract to reach the mandibular nerve (CN V3) and carry proprioceptive information from the face and the teeth. Axons of these neurons run in the mesencephalic tract and innervate a number of central nuclei, including the trigeminal motor nucleus.
