=====Nodule of the vermis=====
{{ https://upload.wikimedia.org/wikipedia/commons/9/97/Gray704.png}}

The nodule (nodular lobe), or anterior end of the inferior [[vermis]], abuts against the [[roof of fourth ventricle]], and can only be distinctly seen after the [[cerebellum]] has been separated from the [[medulla oblongata]] and [[pons]].

On either side of the nodule is a thin layer of white substance, named the [[posterior medullary velum]].

It is semilunar in form, its convex border being continuous with the white substance of the cerebellum; it extends on either side as far as the [[flocculus]].
