The arbor vitae is a structure found in the cerebellum, which is the part of the brain responsible for coordinating voluntary movements and maintaining balance and posture.
The term ‘arbor vitae’ translates to ‘tree of life’ in Latin, aptly describing the tree-like appearance of the white matter seen in cross-section. This white matter consists of myelinated axons that facilitate communication between different parts of the cerebellum and other brain regions.
Understanding the role of the arbor vitae is essential because it highlights how crucial the cerebellum is in integrating sensory information and fine-tuning motor activity. Damage to this area can lead to coordination problems and other motor skill deficits.
