Quizplus · Accepted Answer

Lumbar puncture is the procedure done to collect a sample of cerebrospinal fluid (CSF) from the subarachnoid space below the end of the spinal cord. A needle is inserted between two lumbar vertebrae to withdraw a small amount of fluid for testing. Craniectomy, diskectomy, and laminectomy are surgical procedures done in the head or spine but are not used to collect CSF samples.
