Arbor vitae (anatomy)
Arbor vitae (pronounced: /ˈɑːrbɔːr ˈvaɪtiː/), also known as the tree of life, is a term used in anatomy to refer to the cerebellar white matter, which, when sectioned sagittally, exhibits a tree-like appearance. The term is Latin in origin, with "arbor" meaning "tree" and "vitae" meaning "of life".
Etymology
The term arbor vitae is derived from Latin, where "arbor" means "tree" and "vitae" means "of life". This name was given due to the tree-like appearance of the cerebellar white matter when it is cut sagittally.
Anatomy
The arbor vitae is located in the cerebellum, one of the primary parts of the brain. It is composed of white matter, which is responsible for transmitting signals in the brain. The arbor vitae extends into the cerebellar cortex, dividing it into numerous thin, flattened cerebellar folia.
