Fastigiobulbar tract

a fibre bundle originating in the fastigial nucleus (nucleus tecti) of both sides, passing out of the cerebellum in the inferior cerebellar peduncle (corpus restiforme), and distributing its fibres to the vestibular nuclei and other cell groups in the medulla oblongata. Prominent crossed fibres loop over the dorsal surface of the superior cerebellar peduncle before turning ventrally, forming the uncinate bundle of Russell.

Synonym: tractus fastigiobulbaris.
