The cerebellum (Cerebellum) is part of the brain. The cerebellum lies posterior to the brainstem and, separated from the tentorium, is located below the occipital lobe of the cerebrum in the posterior cranial fossa. Together with the medulla oblongata (myelencephalon) and the pons (pons), it forms the rhombencephalon. The cerebellum and pons are collectively referred to as the metencephalon.
Anatomy
The cerebellum is connected to the rest of the central nervous system via the three Cerebellar peduncles.
Cerebellar nuclei
The cerebellum contains four nuclear groups:
Blood supply
The cerebellum receives its blood supply from the three cerebellar arteries:
Clinical relevance
Lesions in the cerebellar hemisphere cause ipsilateral Ataxia of the extremities. A lesion in the vermis of the cerebellum causes truncal ataxia[^1].
