Meninges
The dura mater is composed of dense irregular connective tissue. The thin arachnoid membrane adheres to the dura and extends trabeculae across the subarachnoid space to the pia. The pia mater lies directly on, and accompanies blood vessels into, the central nervous system. The prominent subdural space and the displacement of the pia, seen here, are artifactual. 40x
