Which of the following shows the correct order of meningeal layers of the brain (from closest to the outermost layer)

Question

BlackTom AI · Accepted Answer

When thinking about the protective coverings of the brain, it helps to recall the anatomical arrangement from the innermost to the outermost layer. 
Option 1: 'arachnoid mater; dura mater; pia mater' places arachnoid before dura and pia, which is not the actual sequence starting from the brain surface. The pia mater is the innermost layer, so this ordering is incorrect. 
Option 2: 'pia mater; dura mater; arachnoid mater' starts with the correct innermost layer but then places dura mater directly outside pia and then arachnoid, skipping the proper middle position. The known order is pia, then arachnoid, then dura, so this arrangement misplaces the middle and outer layers. 
Option 3: 'dura mater; arachnoid mater; pia mater' reverses the entire order, presenting the outermost layer first and the innermost last. This is the opposite of the true sequence, so it is incorrect. 
Option 4: 'pia mater; arachnoid mater; dura mater' correctly lists the layers from innermost to outermost: pia mater (closest to brain), then arachnoid mater, then dura mater (outermost). This matches the standard anatomical arrangement. 
In summary, the accuracy hinges on knowing the correct innermost-to-outermost progression, which makes Option 4 the valid choice and the others incorrect for misordering the layers.
