Spiderweb-like (hence the name) arachnoid layer is one of the three meninges, the membranes that cover the brain and spinal cord. It is interposed between the two other meninges, the more superficial dura mater and the deeper pia mater, and is separated from the pia mater by the subarachnoid space.
Arachnoid mater
Pia Mater
The thickest and strongest meningeal layer is the dura mater. It is composed of dense connective tissue and serves as a protective barrier for the brain and spinal cord. The dura mater also plays a role in anchoring the brain within the skull and contains structures such as blood vessels and venous sinuses. Its resilience helps protect the central nervous system from injury.
The middle layer of the atmosphere is the Mesosphere.
The chromosphere is the middle layer of the sun's atmosphere.
Molluscs typically have three main tissue layers: the outer layer (epidermis), middle layer (connective tissue), and inner layer (gastrodermis). These layers help provide structure and support to the mollusc's body.
Arachnoid matter
The middle meningeal layer is called the Arachnoid Mater. Its between the outermost Dura Mater and innermost Pia Mater
the dura
The rough, thick, and leathery meningeal layer is the dura mater.
its the dura mater, the layer is called the periosteal layer.
The meningeal layer of the skull, specifically the dura mater, provides essential protection for the brain by acting as a tough outer covering that safeguards against physical impacts and injury. It also plays a crucial role in supporting the structure of the central nervous system by forming partitions between different brain regions, such as the falx cerebri and tentorium cerebelli. Additionally, the meningeal layer is involved in the circulation of cerebrospinal fluid, which helps cushion the brain and maintain its chemical environment.

A subdural hematoma is a collection of blood in the space between the outer layer (dura) and middle layers of the covering of the brain (the meninges). It is most often caused by torn, bleeding veins on the inside of the dura as a result of a blow to the head.The meninges are layers or covers of the brain.There are 3 meninges but only 2 ways which blood can collect: EPIDURAL, SUBDURAL, SUBARACHNOID.Dr. evans onyango

The opaque middle layer of the eyeball is called the choroid. It is rich in blood vessels and helps to supply nutrients and oxygen to the retina, which is the light-sensitive layer at the back of the eye.
