Verified step by step guidance1
Step 1: Understand the meninges' role and location. The meninges are protective layers surrounding the brain and spinal cord, consisting of three layers: dura mater, arachnoid mater, and pia mater.
Step 2: Identify the relative positions of the meninges. The dura mater is the outermost layer, closest to the skull, making it the most superficial. The arachnoid mater lies beneath the dura mater, and the pia mater is the innermost layer, directly adhering to the brain and spinal cord.
Step 3: Recall the correct order from superficial to deep. The sequence is dura mater (outermost), arachnoid mater (middle layer), and pia mater (innermost).
Step 4: Compare the given options to the correct order. The correct answer matches the sequence: dura mater, arachnoid mater, pia mater.
Step 5: Confirm the reasoning by visualizing or referencing anatomical diagrams of the meninges to reinforce the spatial arrangement.
