2023年11月3日 · Specifically, the CSF passes between the inner two meningeal layers (arachnoid and pia) which are together called the leptomeninges. This article will discuss the anatomy and function of the cranial and spinal meninges. The cranial dura mater is the outermost meningeal layer, consisting of dense irregular connective tissue.
Meninges: What They Are & Function - Cleveland Clinic
Meninges are three membranes layers that cover and protect your brain and spinal cord (central nervous system). These membranes — the dura mater, arachnoid mater and pia mater — protect and anchor your brain and provide a support system for blood vessels, nerves, lymphatics and the cerebrospinal fluid that surrounds your central nervous system.
Meninges - Wikipedia
In mammals, the meninges are the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid is located in the subarachnoid space between the arachnoid mater and the pia mater. The primary function of the meninges is to protect the central nervous system .

Meninges | Structure, Function & Location | Britannica
Meninges, three membranous envelopes—pia mater, arachnoid, and dura mater—that surround the brain and spinal cord. Cerebrospinal fluid fills the ventricles of the brain and the space between the pia mater and the arachnoid. The primary function of the meninges and of the cerebrospinal fluid is to
