Which term refers to a procedure that removes CSF from the spinal surrounding area for diagnostic tests?

• A. Respiratory system
• B. Nasal mucous membrane
• C. Lumbar puncture
• D. Sinus cavities

Answer: (C)

A lumbar puncture is the procedure used to remove cerebrospinal fluid from the spinal area for diagnostic testing. In this procedure, a needle is carefully inserted into the lower back to reach the lumbar subarachnoid space and withdraw CSF for analysis. This sample can help diagnose meningitis, subarachnoid hemorrhage, infections, or certain neurological conditions that affect CSF. The other terms refer to parts of the nasal or respiratory system and have no role in sampling CSF, so they aren’t relevant to this procedure.
