Spinal cord
Procedures

The spinal cord ends at the level of vertebrae L1–L2, while the subarachnoid space – the compartment that contains cerebrospinal fluid – extends down to the lower border of S2. Lumbar punctures in adults are usually performed between L3–L5 (cauda equina level) in order to avoid damage to the spinal cord. In the fetus, the spinal cord extends the full length of the spine and regresses as the body grows.
