To solve the problem, we need to identify the fluid that serves as a shock-absorbing medium and protects the brain against shocks/jerks, along with the meninges and cranium.
1. Function of Cerebrospinal Fluid (CSF):
The cerebrospinal fluid (CSF) is a clear fluid that surrounds the brain and spinal cord. It serves several important functions:
2. Conclusion:
The fluid that serves as a shock-absorbing medium and protects the brain, along with the meninges and cranium, is cerebrospinal fluid (CSF).
Final Answer:
The correct answer is (B) Cerebrospinal fluid.
