vermis

 [ver´mis] (L.)
a wormlike structure, particularly the vermis cerebelli.
vermis cerebel´li (vermis of cerebellum) the median part of the cerebellum, between the two cerebellar hemispheres.

ver·mes

(ver'mis, -mēz),
1. A worm; any structure or part resembling a worm in shape.
2. Vermis cerebelli, the narrow middle zone between the two hemispheres of the cerebellum; the portion projecting above the level of the hemispheres on the upper surface is called the superior vermis; the lower portion, sunken between the two hemispheres and forming the floor of the vallecula, is the inferior vermis.
