What is an intermediate meninx?

Arachnoid The middle meninges appear as a thin, transparent membrane on the surface of the brain. … a small subarachnoid space separates the arachnoid from the pia mater. In some areas, black blood vessels are visible under the arachnoid.

What is the difference between the middle meninges and the outer meninges?

The meninges are layered, the outer layer is the dura mater, the middle layer is the arachnoid, and the inner layer is the pia mater.The space between the dura mater and the arachnoid is subdural space. The subarachnoid space above the pia mater is the subarachnoid space.
