Fig. 29 Section through the middle of the recessus lateralis. At this level the 

 walls of the recess and of its anterior diverticulum are membranous, though not 

 plexiform, save for the body of the cerebellum in front and the area acustico-lat- 

 eralis behind. The plexus chorioideus which forms the roof of the recess is at- 

 tached to the parts here illustrated a very short distance dorsally of this level.
