The meninges (/məˈnɪndʒiːz/, singular: meninx (/ˈmiːnɪŋks/ or /ˈmɛnɪŋks/), from Ancient Greek: μῆνιγξ mēninx “membrane”, adjectival: meningeal /məˈnɪndʒəl/) are the membranes that envelop the central nervous system.

The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater.


The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system.


Meningiomas are by far the most common tumors arising from the meninges.
