===Caudal Spinal Cord Development===
In late development, the spinal cord extends along the entire length of the spinal canal (formed by the spinal vertebrae). The spinal cord then terminates at the 'conus medullaris' in the middle of the lumbar spine. In adults the spinal cord ends at the beginning of the lumbar psine. Lumbar and sacral nerves extend via the 'cauda equine'.

Therefore in neonates CSF taps must be caudal to the conus medullaris to avoid damaging the spinal cord.
