Question

What are the three meninges of the brain? Where are they present.

Answer 1

The brain is located in the cranial cavity and is covered by three cranial meninges.

1. The outer thick layer is Duramater which lines the inner surface of the cranial cavity.
2. The median thin layer is the Arachnoid mater which is separated from the dura mater by a narrow subdural space.
3. The innermost layer is Piamater which is closely adhered to the brain but separated from the arachnoid mater by the subarachnoid space.
