What are the Functions of the Meninges? - ANS 1. Encase and protect brain and spinal cord.
2. Supports Vessels and Sinus, connective tissue membrane.
3. Encloses subarachnoid space.
4. Acts as blood-brain barrier between the arachnoid and Pia mater.
What is Kernig's Sign? - ANS When bent at the hip and knee at 90 degree angles, and
subsequent extension in the knee is painful.
