What are the functions of cerebrospinal fluid (CSF)?

Cerebrospinal fluid (CSF) plays several crucial roles in maintaining the health and function of the central nervous system. Among its primary functions, CSF cushions the brain and spinal cord, providing a protective layer that prevents injury from impacts and sudden movements. This cushioning is vital for safeguarding delicate neural structures against physical stress.

CSF also has additional important functions, including removing waste products from the brain, which is essential for maintaining a healthy environment around neuronal tissues and facilitating proper brain function. While insulating properties and neurotransmitter production are essential functions in the nervous system, they do not specifically pertain to the role of cerebrospinal fluid. Instead, the thermoregulation and neurotransmitter functions are mediated by other mechanisms and components within the nervous system. The recognition of CSF as a protective cushion highlights its significance in supporting the overall integrity and functionality of the brain and spinal cord.
