What does CSF stand for?

The term CSF stands for cerebrospinal fluid. This crucial fluid surrounds and cushions the brain and spinal cord, providing protection, delivering nutrients, and removing waste. It plays a significant role in maintaining the homeostasis of the central nervous system, and any abnormalities in its composition or volume can indicate various neurological conditions. The other options do not accurately represent this specific and recognized term, as cerebrospinal fluid is the standard terminology used in medical contexts.
