5. The potential space found below the dura mater
8. The aqueduct that connects the 3rd ventricle to the 4th ventricle
9. The sickle shaped vertical fold of dura mater found in the longitudinal fissure
12. the foramen that connects the lateral ventricles to the 3rd ventricle
17. The ventricles which contain the choroid plexus
18. The structures that absorb the CSF from the subarachnoid space
19. The glial cells that produce the cerebral spinal fluid
20. The outermost meninx, also the thickest

1. Where the CSF is drained into in order to enter the blood stream

7. The space containing the cerebrospinal fluid
10. The structure that produces the cerebrospinal fluid.
11. The fluid filled spaced within the brain
13. The innermost meninx, the only meninx that goes into the sulci of the brain
14. An extension of dura mater that separates the cerebellum from the cerebrum
15. The foramen that exits laterally sending CSF into the subarachnoid space
