{{Main|Cerebellum}}

The cerebellum is divided into an [[anterior lobe of cerebellum|anterior lobe]], a [[posterior lobe of cerebellum|posterior lobe]], and the [[flocculonodular lobe]].{{sfn|Guyton & Hall|2011|p=699}} The anterior and posterior lobes are connected in the middle by the [[cerebellar vermis|vermis]].{{sfn|Gray's Anatomy|2008|p=298}} Compared to the cerebral cortex, the cerebellum has a much thinner outer cortex that is narrowly furrowed into numerous curved transverse fissures.{{sfn|Gray's Anatomy|2008|p=298}}
Viewed from underneath between the two lobes is the third lobe the flocculonodular lobe.<ref>{{cite book |last1=Netter |first1=F. |title=Atlas of Human Anatomy Including Student Consult Interactive Ancillaries and Guides. |date=2014 |publisher=W B Saunders Co |location=Philadelphia, Penn. |isbn=978-1-4557-0418-7 |page=114 |edition=6th}}</ref> The cerebellum rests at the back of the [[posterior cranial fossa|cranial cavity]], lying beneath the occipital lobes, and is separated from these by the [[cerebellar tentorium]], a sheet of fibre.{{sfn|Gray's Anatomy|2008|p=297}}

It is connected to the brainstem by three pairs of [[nerve tract]]s called [[cerebellar peduncle]]s. The [[superior cerebellar peduncle|superior pair]] connects to the midbrain; the [[middle cerebellar peduncle|middle pair]] connects to the medulla, and the [[inferior cerebellar peduncle|inferior pair]] connects to the pons.{{sfn|Gray's Anatomy|2008|p=298}} The cerebellum consists of an inner medulla of white matter and an outer cortex of richly folded grey matter.{{sfn|Gray's Anatomy|2008|p=297}} The cerebellum's anterior and posterior lobes appear to play a role in the coordination and smoothing of complex motor movements, and the flocculonodular lobe in the maintenance of [[Equilibrioception|balance]]{{sfn|Guyton & Hall|2011|pp=698–9}} although debate exists as to its cognitive, behavioural and motor functions.{{sfn|Squire|2013|pp=761–763}}
