synonym: arachnoid mater
https://doi.org/10.1351/goldbook.10424

Web like membrane that lies between the outer (and much thicker) dura mater and the deeper pia mater, and which covers the brain.

Note: The arachnoid membrane is separated from the pia mater by the subarachnoid space, in which the cerebrospinal fluid flows and is absorbed by the arachnoid villi.
