Meninges of the Brain 13. Identify the meningeal (or associated) structures described below: 1. outermost meninx covering the brain; composed of tough fibrous connective tissue 2. innermost meninx covering the brain; delicate and highly vascular 3. structures instrumental in returning cerebrospinal fluid to the venous blood in the dural sinuses 4. structure that forms the cerebrospinal fluid 5. middle meninx; like a cobweb in structure 6. its outer layer forms the periosteum of the skull 7. a dural fold that attaches the cerebrum to the crista galli of the skull 8. a dural fold separating the cerebrum from the cerebellum Cerebrospinal Fluid 14. Label the structures involved with circulation of cerebrospinal fluid on the accompanying diagram. Add arrows to the figure above to indicate the flow of cerebrospinal fluid from its formation in the lateral ventricles to the site of its exit from the fourth ventricle. Then fill in the blanks in the following paragraph. Cerebrospinal fluid flows from the fourth ventricle into the 1 space surrounding the brain and spinal cord. From this space it drains through the 2 into the 3 . 1. 2. 3.
