"It most involves the arachnoid and pia mater, or the leptomeninges ("thin meninges")"
subarachnoid space
The outermost layer of meninges is called as Dura matter. It has got outer and inner layers in Dura matter. Together they form various venous sinuses in the meninges.
middle layer of meninges is called arachnoid
The arachnoid mater is the middle layer of the meninges that forms a loose covering over the brain. It is located between the dura mater (outer layer) and the pia mater (inner layer) of the meninges.

The layer of meninges that is attached to the skull is called the dura mater. It is the outermost layer of the three meninges and provides a protective covering for the brain and spinal cord. The dura mater is tough and fibrous, anchoring itself to the inner surface of the skull.
The middle layer of the brain with cottony fibers is likely referring to the arachnoid mater, one of the meninges that surround the brain. It is a delicate, web-like membrane filled with thin, fibrous strands that provide cushioning and support for the brain.
False
the three layers of meninges are as follows: Outer layer(layer closet to the skull): known as the Dura Mater. Middle layer: known as the Arachnoid Inner layer(layer closest to the cerebral cortex): known as the Pia Mater ***The meninges contain cerebral spinal fluid (which is produced in the brain stem) which as a shock absorber. The meninges also provide extra support and protection for the brain.controls involuntary muscle
The layer of meninges that is in direct contact with the surface of the brain is called the pia mater. It is the innermost layer of the meninges and provides a protective barrier around the brain, allowing for the exchange of nutrients and waste products with brain tissue.
