Vermis cerebelli, also known as the cerebellar vermis, refers to the central part of the cerebellum that is involved in the coordination of movement, as well as balance and posture. Synonyms for vermis cerebelli include the cerebellar midline, median lobe of the cerebellum, and the worm-shaped structure of the cerebellum. Other related terms that are commonly used in neuroscience and anatomy include the lateral cerebellum, flocculonodular lobe, and the cerebellar hemispheres. While the vermis cerebelli plays a vital role in motor control, damage or injury to this area can result in a range of neurological symptoms, including ataxia, dysarthria, and nystagmus.
