Exploration of the basal aspects of the medulla, pons and cerebellum
Arteries supplying choroid plexus of lateral recess
This view is at right angles to the two previous ones, and the midline of the brain stem is now at the bottom of the view. The flocculus has been removed and the anterior inferior cerebellar artery turned medially together with the choroid plexus previously seen. One principal choroidal artery and several small vessels are thus exposed in their course into the plexus. In the depths of the dissection the peduncle of the flocculus is visible. The bulbar roots of Nn. IX, X, and XI have been cut away.
