The trigeminocerebellar fibers are fibers in the inferior cerebellar pedunclesJ. Nolte, The Human Brain - An Introduction to its Functional Anatomy 6e (2008) p499, 509t which transmit proprioceptive information from the face to the

cerebellum The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cerebe ...

. This information originates in proprioceptors (e.g. muscle spindles) in the face. Primary cell bodies are in the mesencephalic nucleus of the

trigeminal nerve In neuroanatomy, the trigeminal nerve ( lit. ''triplet'' nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and che ...

. These fibers transmit information to secondary afferent cell bodies in the oralis and interpolaris portions of the spinal trigeminal nucleus plus the principal nucleus. Axons from the spinal nucleus (and a smaller number from the principal nucleus) then form the trigeminocerebellar tract and ascend to the cerebellum.
