c. Arachnoid mater
d. Pia mater

검증된 단계별 안내

Understand that the meninges are the protective membranes that cover the brain and spinal cord, consisting of three layers: dura mater, arachnoid mater, and pia mater.

Recall the order of these layers from the outermost to the innermost: dura mater is the tough outer layer, arachnoid mater is the middle web-like layer, and pia mater is the delicate inner layer that closely adheres to the brain tissue.

Identify that the question asks for the innermost layer, which means the layer directly adjacent to the brain tissue.

Eliminate options that do not correspond to meningeal layers: corpus callosum is a bundle of nerve fibers connecting the two cerebral hemispheres, so it is not a meningeal layer.

Conclude that the correct answer is the pia mater, as it is the delicate innermost meningeal layer adjacent to the brain.

Meninges

The meninges are three protective membranes that surround the brain and spinal cord. They consist of the dura mater, arachnoid mater, and pia mater, each with distinct locations and functions in protecting the central nervous system.

Pia Mater

The pia mater is the innermost layer of the meninges, a thin and delicate membrane that closely adheres to the surface of the brain and spinal cord, following their contours and providing a protective barrier.

Dura Mater and Arachnoid Mater

The dura mater is the tough, outermost layer of the meninges, while the arachnoid mater is the middle, web-like layer. Both serve protective roles but are located farther from the brain tissue compared to the pia mater.
