The Arbor Vitae, which translates to “Tree of Life” in Latin, primarily refers to a specific structure in the brain. It is a distinctive arrangement of white matter located in the cerebellum, which is involved in coordinating voluntary movements and maintaining posture and balance.
The term is also used in a broader context to describe several other plants and structures in different fields, but in neuroscience, it specifically pertains to its unique tree-like appearance when viewed in cross-section. This resemblance to a tree structure gives the Arbor Vitae its name, highlighting its role and importance in the overall functionality of the cerebellum.
