Embryonic folding By the end of the fourth week of development, the embryo has already begun to take human form. It is nearly completely lined on the outside with ectoderm. Inside, the neural tube is continuing to develop within the dorsal mesenchyme. Adjacent to the neural tube, somites are forming in a segmental fashion. Lateral to this, intermediate mesoderm is beginning to form structures of the urogenital system and gonads. The lateral plate mesoderm had split into splanchnopleuric and s...
