Step 1: Analyze the components of the Central Nervous System (CNS)

The human Central Nervous System consists of the brain and the spinal cord. These delicate organs are protected by three layers of connective tissue membranes known as the cranial meninges.

The three layers of the meninges are:

  • Dura mater: The outermost tough fibrous layer.
  • Arachnoid mater: The middle thin, web-like layer.
  • Pia mater: The innermost vascular layer in direct contact with the brain tissue.

Step 3: Identify the outlier
