Arrange the protective layers of the brain from outside to inside?
The brain is encased inside the skull followed by 3 membranous coverings called meninges.
1) Outer layer – Dura mater provides support for large venous sinuses.
2) Middle layer – Thin arachnoid mater acts as a cushion.
3) Inner layer – Pia mater remains in close contact with the brain and provides scaffolding for the blood vessels and capillaries of the brain.
