Q

List the three meningeal layers and state their location in relation to the skull and the brain tissue

A

PAD

Pia mater is closest to the brain tissue and dips into the sulci and fissures.

Arachnoid mater is above the pia (in the middle of the PAD) and has a subarachnoid space below it with cerebrospinal fluid.

Dura mater is the thick leathery covering that is the outer most meningeal layer. It is closest to the bone of the skull.
