Question

Quizplus · Accepted Answer

The pia mater is the layer of the meninges that is in direct contact with the surface of the brain. This layer is very thin and highly vascularized, and it provides support and nutrition to the underlying tissue. The dura mater is the outermost layer of the meninges, and it is thicker and tougher than the other layers. The subdural space is a potential space between the dura mater and arachnoid layer, and it is normally filled with a small amount of fluid. The arachnoid layer is the middle layer of the meninges, and it is separated from the pia mater by the subarachnoid space, which contains cerebrospinal fluid.
