The middle element of the meninges is the arachnoid membrane
The arachnoid mater is the layer of the meninges that contains web-like filaments known as the arachnoid trabeculae. These filaments extend between the arachnoid mater and the pia mater.

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.
The meninges (from the Greek meninx, meaning "membrane") cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and 3) the pia mater. The dura mater is the outermost layer covering the central nervous system. The arachnoid (from the Greek arachne, meaning "spider") is a web-like network of collagen and elastic fibers. The innermost layer of the meninges is the pia mater. The pia mater is firmly attached to the neural tissue of the spinal cord and brain. Cerebrospinal fluid fills the space between the pia matter and the arachnoid membrane. Most of the blood vessels that supply blood to the central nervous system are in the pia mater.The outermost layer of the brain membrane (meninges) is the dura mater, "tough mother". The middle layer of meninges is the arachnoid (spider) mater which helps stabilize the brain inside the skull. Finally the pia mater overlies the brain directly.
The arachnoid mater forms the middle layer of the meninges. It consists of delicate, web-like fibers that lie between the dura mater and the pia mater.

Dura mater and pia mater are two different layers of connective tissue that surround the brain called meninges. Dura mater is Latin for "tough mother" and is attached to the inner surface of the skull. Pia mater is Latin for "soft mother" and lines the outer surface of the brain. Between the two is a third meningeal layer called the arachnoid mater because of its web like appearance.
As web is to spider.
There are three layers of meninges around the brain and spinal cord (these are continuous between the two structures). The outermost layer is the Dura mater, the toughest and most protective layer. The middle is the arachnoid layer, and the pia mater is the innermost layer.The protective layers of the brain are the 3 meninges. From the outermost layer to the innermost layer, they are the dura mater, the arachnoid, and the pia mater.Dura mater,arachnoid mater,pia mater,skullThe protective membranes surrounding the brain are called the meninges, and from outside to in are named the dura mater, arachnoid mater, and the pia mater.meninges
the web just keeps the still so then the spider can fast on it's prey
The middle of a spider's web is called the "hub." This is where the spider typically waits for prey to become trapped in the web.
Is a spider and a web living or non living??
