Arbor vitae (anatomy)

The arbor vitae /ˌɑːrbɔːr ˈvaɪtiː/ (Latin for "tree of life") is the cerebellar white matter, so called for its branched, tree-like appearance. In some ways it more resembles a fern and is present in both cerebellar hemispheres.[1] It brings sensory and motor information to and from the cerebellum. The arbor vitae is located deep in the cerebellum. Situated within the arbor vitae are the deep cerebellar nuclei; the dentate, globose, emboliform and the fastigial nuclei. These four different structures lead to the efferent projections of the cerebellum.[2]

Godfrey Blount's 1899 book Arbor Vitae was ‘a book on the nature and development of imaginative design for the use of teachers and craftsmen’.[3]
