Explanation : Between the 17th and 30th day after conception (or 4 to 6 weeks after the first day of a woman=s last menstrual period), the neural tube forms in the embryo (developing baby) and then closes. The neural tube later becomes the baby=s spinal cord, spine, brain, and skull.
Early Embryonic Development of Nervous System: The neuroectoderm begins to fold inward to form the neural groove. As the two sides of the neural groove converge, they form the neural tube, which lies beneath the ectoderm.
