Is A lumbar puncture is the sampling of CSF obtained by inserting a needle into epidural space region?

No, a lumbar puncture is not performed by inserting a needle into the epidural space region. It involves accessing the subarachnoid space in the lumbar region of the spine to collect cerebrospinal fluid (CSF) for diagnostic and therapeutic purposes. The epidural space is a separate compartment located between the vertebrae and the dura mater, which contains fat and blood vessels.
