The Surfaces of the cerebellum and brain stem
Posterior inferior aspect
The medulla has been sectioned through decussation of the pyramids. The arachnoid membrane enclosing the cisterna magna has been cut away to reveal parts of the vermis (9). All of the arterial branches spreading over the cerebellar surface in this view are derived from the posterior inferior cerebellar arteries.
1 . Superior semilunar lobe (crus I ansiform lobule)
2 . Horizontal cerebellar sulcus (intercrural sulcus)
3 . Inferior semilunar lobe (crus II ansiform lobule)
4 . Biventral lobule (dorsal paraflocculus)
5 . Posterior inferior cerebellar artery
6 . Pyramidal decussation
7 . Tonsil (ventral paraflocculus)
8 . Pyramid (of vermis)
9 . Uvula (of vermis) (seen in depths of posterior cerebellar incisure)
10 . Medial aperture fourth ventricle (foramen Magendie)
