==Neural Differentiation==
In the early embryo as shown in the images above, the neural tube is formed and represents the initial stages of the formation of the brain and spinal cord. As the embryo develops, the neural tube continues to develop in conjunction with the formation of the vertebrae of the spine.
===Development of Vertebrae===
Formation of the cells that will be the precursors to the spinal vertebrae align in an intersegmental fashion to the neural cells of the spinal cord, in a form of bridging pattern. Therefore each neural cell has a spinal vertebrae precursor cell between itself and the adjacent neural cell such that the spinal cell effectively overlaps the edges of two neural cells. This ensures that as the spine and spinal cord develop the spinal nerves become aligned to the spaces between the vertebrae that will eventually become seperated by intervertebral discs.
