the arachnoid layer is located between the dura and pia matter in the skull and around the spinal cord.
further: these three layers make up the meninges, a system of membranes that surround and help protect the CNS (central nervous system) along with the help of the cerebral spinal fluid. dura is the outermost layer and pia is the innermost layer; arachnoid falls in between these two.
Around the spinal cord.
Arachnoid granulations (or arachnoid villi) are small protrusions of the arachnoid (the thin second layer covering the brain) through the dura (the thick outer layer).
The middle element of the meninges is the arachnoid membrane
middle layer of meninges is called arachnoid

The middle meningeal layer is called the Arachnoid Mater. Its between the outermost Dura Mater and innermost Pia Mater
t is the tough leathery meningeal layer
Deep to the arachnoid layer of the meninges is the pia mater.
