The human brain is well protected by cranial meninges. Which of the following layers is the innermost and remains in contact with the brain tissue?

Options

  1. APia mater
  2. BDura mater
  3. CArachnoid
  4. DPleura

Correct answer

A. Pia mater

Step-by-step solution

The cranial meninges consist of an outer layer called dura mater, a very thin middle layer called arachnoid, and an inner layer called pia mater. The pia mater is the innermost meningeal layer that remains in direct contact with the brain tissue. The pleura is the double-layered membrane enclosing the lungs, not the brain. Answer: Pia mater
