What is the function of CSF in relation to the brain and spinal cord?

• A. Provides nutrients
• B. Cushions and protects
• C. Regulates temperature
• D. Stimulates growth

Answer: (B)

Cerebrospinal fluid (CSF) plays a critical role in the central nervous system, primarily by cushioning and protecting the brain and spinal cord. The brain is composed of soft tissue, making it vulnerable to injury from impacts or sudden movements. CSF acts as a buffer, providing mechanical protection by absorbing shocks that could otherwise harm brain structures. This cushioning effect helps to prevent damage and maintain the integrity of the central nervous system. In addition to its protective function, CSF helps maintain a stable environment for the brain and spinal cord, contributing to homeostasis. While CSF does provide some nutrients and facilitate waste removal, its primary role in cushioning and protection is vital to keep the delicate neural tissues safe during physical stress.
