Further along into spinal development, each vertebral body develops three centres of ossification which are separated by cartilage growth plates. Each half of the two vertebral arches that surround the developing spinal cord (neural tube) have their own ossification centre facilitating the development of vertebral processes, ribs and other bone structures related to the LPM including the scapula and pelvis.

===Development of the Brain===
===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.
