What is the normal color of cerebrospinal fluid?

• A. Opaque yellow
• B. Clear and colorless
• C. Cloudy white
• D. Bright red

Answer: (B)

Cerebrospinal fluid (CSF) is a clear and colorless fluid that surrounds the brain and spinal cord, acting as a cushion and providing essential nutrients. Under normal conditions, CSF maintains this clear appearance, which is critical for proper neurological function. When CSF appears cloudy or discolored, it often indicates the presence of abnormal substances such as white blood cells, bacteria, or protein, suggesting conditions like infection or inflammation. Opaque yellow, cloudy white, and bright red would indicate potential pathological processes and are not characteristics of normal CSF. Understanding the normal appearance of cerebrospinal fluid is crucial for healthcare professionals in assessing neurological health and diagnosing various conditions.
