Brain is covered by 3 layers of meninges

1) Outer Duramater

2) Middle Arachnoidlayer

3) Inner piamater

Arachnoid mater is a thin transparent membrane which is closely related to the internal surface of duramater.

It is separated from the duramater by a potential subdural space which is filled with capillary layer of tissue fluid
