Leptomeninges

«The inner two meninges, the arachnoid, and the pia mater, between which circulates the cerebrospinal fluid [1].» «(...). Because the arachnoid is connected to the pia by cobweb-like strands, it is structurally continuous with the pia, hence the name pia-arachnoid or leptomeninges. They are responsible for the production of beta-trace protein (prostaglandin D synthase), a major cerebrospinal fluid protein [2-4].»
