section::::clinical significance.









































the cauda equina exists within the lumbar cistern, a gap between the arachnoid membrane and the pia matter of the spinal cord, called the subarachnoid space. cerebrospinal fluid also exists within this space. because the spinal cord terminates at level l1/l2, lumbar puncture (or colloquially, "spinal tap") is performed from the lumbar cistern between two vertebrae at level l3/l4, or l4/l5, where there is no risk of accidental injury to the spinal cord, when a sample of csf is needed for clinical purposes.
