Question

Which of the following protects the brain from shock?

• A. Durameter
• B. Cerebrospinal fluid
• C. Arachnoid membrane
• D. Cranium

Answer 1

Answer: (B)

Cerebrospinal fluid

• CSF occupies the subarachnoid space (the space between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord.
• The primary function of CSF is to cushion the brain within the skull and serve as a shock absorber for the central nervous system.
• CSF also circulates nutrients and chemicals filtered from the blood and removes waste products from the brain.

So, the correct answer is option B.
