What is the primary role of cerebrospinal fluid (CSF)?

Protecting the spinal cord
Transporting nutrients to neurons
Regulating intracranial pressure
Providing cushioning for the brain

The correct answer is: Providing cushioning for the brain

The primary role of cerebrospinal fluid (CSF) is to provide cushioning for the brain. This clear fluid surrounds the brain and spinal cord, acting as a protective barrier against trauma. The cushioning effect helps to absorb shocks that could otherwise cause injury to delicate neural tissues, stabilizing the brain's position within the skull and minimizing the impact of external forces. Additionally, while CSF does play a role in protecting the spinal cord and regulating intracranial pressure, its most significant and immediate function is facilitating a protective environment for the brain. This cushioning effect is vital for the maintenance of overall neurological health and function.
