5. Projections of arachnoid mater that transport CSF out of the subarachnoid space and into the superior sagittal sinus
8. A clinical test performed with a needle inserted into the subarachnoid space to withdraw CSF for diagnostic purposes
11. CSF enters the ____ blood in the superior sagittal sinus via the subarachnoid granulations
13. CSF-filled space that runs the length of the spinal cord
15. Meningeal layer superficial to the space occupied by CSF in the brain
16. CSF flows from the lateral ventricles into the third ventricle via the _____
17. Network of blood capillaries located in the ventricles of the brain
18. Condition in which excess CSF accumulates in the ventricles of the brain, causing them to become enlarged
20. Ion present in large quantities in the CSF contributing to its buoyancy

9. CSF-filled cavities present in the left and right hemispheres of the cerebrum
10. Meningeal layer deep to the space occupied by CSF in the brain
12. Cells that line the choroid plexus and produce cerebrospinal fluid
14. A clear, colourless liquid providing mechanical and chemical protection for the brain and found in the subarachnoid space
19. Hair-like projections on the surface of ependymal cells that help propel CSF through the ventricular system
