The germinal period (0- 2 wks. After conception) includes the formation of the zygote, rapid cell division forming a 100-celled blastocyst, and implantation. The outer layer of the blastocyst, the trophoblast, develops into the structures that will house and nourish the embryo (amnion, placental, umbilical cord). The inner layer becomes the embryonic disk, which eventually forms the embryo.
