Dura Mater: “the hard mother”
Blood vessels between arachnoid layer and pie mater
Brain touches pie mater

This created a pressure that allow the meninges to cushion your brain, and holds it in place.
On spinal cord: Cervical, thorastic, lumbar, ?
Determining if you have meningitis: Lumbar Puncture
