Cerebral cortex

What are the three layers of the meninges from outermost to innermost?

1. Dura mater (tough, outer layer).

2. Arachnoid mater (middle, web-like layer).

3. Pia mater (delicate, deepest layer).

What are the spaces created by the meninges, and what do they contain?

• Subdural space: Between dura mater and arachnoid mater; contains a thin film of fluid.

• Subarachnoid space: Between arachnoid mater and pia mater; contains CSF

Where is cerebrospinal fluid (CSF) produced?

choroid plexus of the lateral ventricles.

Trace the flow of CSF from its origin to its collection point in the superior sagittal sinus (8 ste0s)
