Question

What are the structures involved in the protection of the brain?

Answer 1

The brain is covered by three connective tissue membrane or meninges.

• Dura mater, which is the outermost thick fibrous membrane.
• Arachnoid membrane, which is the middle thin vascular membrane providing a web-like cushion.
• Pia mater, which is the innermost, thin delicate membrane richly supplied with blood. Meningeal membranes protect the brain from mechanical injury.
