The arachnoid mater is the middle layer of the three cranial meninges. “Meninges” is the collective term for the layers that cover the brain and spinal cord, lining the cranium and vertebral canal. They provide protection to the CNS. The arachnoid mater is deep to the dura mater but superficial to the pia mater. The term “arachnoid” is a reference to the spider web-like appearance of the arachnoid mater fibers, where they attach to the underlying pia mater.

The arachnoid mater is a delicate, impermeable, avascular membrane which is reinforced by the meningeal layer of dura mater. It contributes to the circulation of cerebrospinal fluid throughout the central nervous system.
