Accepted Answer

In a lumbar puncture, fluid is extracted from the subarachnoid space. This space is located between the arachnoid membrane and the pia mater, which covers the spinal cord. The cerebrospinal fluid (CSF) is found in this space and is collected for diagnostic and therapeutic purposes, such as detecting infections or tumors, relieving pressure or administering medication.
