The embryonic stage.

The prenatal development goes through three different stages:
- The germinal stage: Begins at conception and it takes place during the next 2 weeks.
- The embryonic stage: It takes place from week two to eight weeks after conception. During this stage, the embryo begins to differentiate itself into three layers that will become different systems of the body. By week eight, the basic structures of the brain and central nervous system have been established and the organs start to appear.
- The fetus stage: It takes place from week 9 until birth. The systems formed in the previous stage continue to form until they are ready for birth.
