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 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.
The ozone has no subdivided layer. It is only a single layer.
Arachnoid matter
the dura
The middle meningeal layer is called the Arachnoid Mater. Its between the outermost Dura Mater and innermost Pia Mater
The rough, thick, and leathery meningeal layer is the dura mater.
its the dura mater, the layer is called the periosteal layer.

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.
The middle layer of the atmosphere is the Mesosphere.
The three layers of hair are the cuticle (outermost layer), cortex (middle layer responsible for strength and elasticity), and medulla (innermost layer, not always present in all hair types). These layers work together to provide structure and protection to the hair strand.
