Functions of meninges
The meninges: Protect your CNS (central nervous system) from trauma injury to your brain, such as a blow to your head by acting as a shock absorber. They anchor your CNS and keep your brain from moving around within your skull. Provide a support system for blood vessels (including your middle meningeal artery) that deliver blood to your CNS tissues, nerves (including your trigeminal and vagus nerves), lymphatics (drainage system) and cerebrospinal fluid.
