Quizplus · Accepted Answer

To obtain a specimen of CSF, a lumbar puncture (spinal tap), is performed. A needle is inserted through the skin, back muscles, spinal ligaments of an intervertebral space, epidural space, dura mater, and arachnoid mater into the subarachnoid space. The CSF can then be aspirated. The word spinal tap breaks down into the suffix -al meaning pertaining to, the root spin- meaning spine; the word tap is derived from the Old English meaning to open.
