Meninges are the protective membranes surrounding the brain and spinal cord. They are as follows:

2. Arachnoid mater: It is the middle, thin and non-vascular layer of connective tissue having web like appearance. Sub-arachnoid space is present between arachnoid mater and pia mater. It is filled with Cerebrospinal fluid (CSF). 
3. Pia mater: It is the innermost delicate, highly vascular membrane. It lies in close contact with the CNS.
