Answer #1

The central nervous system is derived from the ectoderm during embryogenesis in humans.
In the third week of embryonic development, the neuroectoderm is formed. It produces the neural plate along the dorsal side of the embryo. It is the source of the majority of glial cells and neurons of the central nervous system.
By week 4, the neural tube is produced which is filled with the cerebrospinal fluid.

By week 24-25, the nervous system is able to control few body functions.
