Verified step by step guidance

Step 1: Understand the structure of the spinal cord meninges and associated spaces. The meninges are protective layers surrounding the spinal cord and brain, consisting of three layers: dura mater (outermost), arachnoid mater (middle), and pia mater (innermost). Between these layers are spaces that provide cushioning and protection.

Step 2: Identify the outermost layer and space. The epidural space is the outermost space, located outside the dura mater. The dura mater is the tough, outermost meningeal layer.

Step 3: Move inward to the next layer and space. Beneath the dura mater is the subdural space, followed by the arachnoid mater, which is the middle meningeal layer.

Step 4: Continue inward to the innermost layer and space. Beneath the arachnoid mater is the subarachnoid space, which contains cerebrospinal fluid (CSF). The pia mater is the innermost meningeal layer, directly adhering to the spinal cord.

Step 5: Combine the layers and spaces in order from outermost to innermost: Epidural space, dura mater, subdural space, arachnoid mater, subarachnoid space, pia mater.
