Now let's look at the ventral surface of the cerebellum (the part that overlies the fourth ventricle and faces the dorsal (top) part of the pons. The midline vermis and laterally placed hemispheres are apparent, as are parts of each posterior hemisphere called the "tonsils". On this ventral view the midline nodule and its lateral extension, the flocculus can be seen. The posterolateral fissure (sorry about these darn fissures) lies just caudal to the nodule, and separates the nodule/flocculus or flocculonodular lobe from the posterior lobe. Finally, you can see the three infamous cerebellar peduncles going into and out of the cerebellum, the inferior, middle and superior.
