Characteristics of the Arachnoid Layer
- Intermediate layer
- A meninx composed of delicate CT
- Attached to underlying Pia Mater
- CSF fills the Subarachnoid space
Where is the CSF produced?
In the Choroid Plexus of each Ventricle
Characteristics of the Pia Mater
- Innermost Layer
- Thin, delicate CT that lies directly on the surface of the Brain and Spinal Cord
- Perivascular spaces are tunnels covered with Pia mater
