But soon they begin to differentiate, will have different missions. Thus, the cells are organized in layers, or sheets: over, between and below the disc, technically known as the ectoderm, mesoderm, and endoderm.

Cells that are born in each of these layers are increasingly more different; prepare to give rise to various types of tissues and organs, including the skin and the nervous system, muscles and viscera, and internal mucous membranes of the intestine. Another group of cells of the disc is devoted to shaping the parts needed for the fetus to develop inside the mother. On the one hand, the placenta, which is the organ that the fetus will use to obtain everything you need from your mom. For another, the membranes and amniotic fluid, allowing the fetus to grow in its own protected and stable environment.

Your Baby's Development
