What is a nerve plate?

The neural board is the first phase of the development of the nervous system in human embryology. He was also observed in bird and amphibians, but first becomes visible in human embryos on the day of 19 development. Ectoblast cells that lie on the outer layer of embryo begin to turn into nerve cells, and the nerve plate is first formed as a medio-sagital reinforcement at the end of the primitive lane, where the Embry Middle Line is formed to support the symmetrical development of fetus. The brain is formed from a wider skull, and the back or caudal end is the measure of the spinal cord. A certain growth factor is needed to transform ectodermal cells into skin tissue and at least 50% of the ectoblast weight changes into a nerve plate. Axial mesodermal cells in embryo secrulios that induce a board and axis in the shape of the rod called the formation of nototochord.

Inhibition of signals for a specific growth factor allows parts of ectoderm formovWhether to get into the nerve cells. In places that do not reach the signals, cells outside the nerve cells form into the skin tissue. The neural board is extended and narrowed in the development of the embryo and begins to compose in the third week of embryonic development. The first phase does not proceed when the nerve tube develops from the nerve plate. The upper part of this closed tube is a place where the brain grows while the spinal cord develops off the end end.

Primary non -rules is the name of the whole process. The neural tube eventually closes and parts of the nervous fold turn into cells of the nerve ridge, which are eventually found between what was the nerve plate and the epidermis. These cells are formed into parts of the peripheral nervous system.

nervous plate folding is a complex process, because the whole fold is approaching everywhere. If the part does not close properly, the result is a conditions such as the backbone bifida. Folic acid and cholesterol are important for preventing such defects in human embryology. Vitamin supplementsB _{12 reduce the risk of defects related to the development of the nerve plate.}
