Question

Brain is protected by the skull and the cerebrospinal fluid. Justify.

Answer 1

Answer:

CSF acts as a cushion or buffer for the cortex, providing a basic mechanical and immunological protection to the brain inside the skull and serving a vital function in cerebral autoregulation of cerebral blood flow.

Answer 2

Explanation: Protection: CSF protects the brain tissue from injury when jolted or hit, by providing a fluid buffer that acts as a shock absorber from some forms of mechanical injury. Prevention of brain ischemia: The prevention of brain ischemia is aided by decreasing the amount of CSF in the limited space inside the skull.
