12. Largest portion of the brain.
13. This forms the lateral walls of the 3rd ventricle.
17. Most posterior lobe of the brain.
18. This cerebelli separates the 2 cerebellar hemispheres.
19. This lobe of the brain is where Wericke's area is located.
21. The brain is surrounded and protected by these 3 membranes.
22. These sinuses provide venous drainage from the brain.
23. This lobe is the most anterior of the brain.

1. This ventricle is slit-like and located midline just inferior to the lateral ventricles.
2. This separates the cerebral hemispheres. (2 words)
4. Aqueduct that is a long passageway that communicates between the 3rd and 4th ventricle.

7. The potential space that separates the dura mater and arachnoid membrane.
9. This ventricle is diamond shaped.
10. This cerebelli spreads out like a tent and forms a partition between the cerebrum and cerebellum.
11. The Right and left ventricles lie within this hemisphere.
