Which of the following is the outermost meningeal layer covering the brain?
A
Pia mater
B
Arachnoid mater
C
Epidermis
D
Dura mater
Verified step by step guidance1
Step 1: Understand the structure and function of the meninges, which are protective layers surrounding the brain and spinal cord. The meninges consist of three layers: dura mater, arachnoid mater, and pia mater.
Step 2: Identify the outermost meningeal layer. The dura mater is the thickest and toughest layer, located directly beneath the skull, making it the outermost layer.
Step 3: Differentiate between the other meningeal layers. The arachnoid mater is the middle layer, and the pia mater is the innermost layer, adhering closely to the surface of the brain.
Step 4: Eliminate incorrect options. Epidermis is not part of the meninges; it is the outermost layer of the skin, not related to the brain's protective coverings.
Step 5: Confirm that the correct answer is dura mater, as it is the outermost meningeal layer covering the brain.
