Assessing each function:
Cushioning the brain and spinal cord: Cerebrospinal fluid (CSF) functions as a shock absorber, safeguarding the central nervous system.
Removing metabolic waste: CSF facilitates the expulsion of waste products from the brain.
Transporting nutrients to the brain: CSF supplies vital nutrients to neural tissues.
Transmitting nerve impulses: Nerve impulses are transmitted by neurons via electrical and chemical signals, independently of CSF.
Conclusion: The role incorrectly attributed to CSF among the provided options is the transmission of nerve impulses.
