| Alcohol exposure alters DNA methylation profiles in mouse embryos at early neurulation. |
| Following gastrulation, the Medaka undergoes neurulation and organogenesis. |
| The gastrulation, neurulation and formation of germ layers in Branchiostoma, frog and human beings are then illustrated. |
| After neurulation, paired cavities called Hatschek's diverticula form in the head endoderm. |
| Important developmental processes observed included cleavage, formation of a blastula, epiboly, gastrulation, neurulation, organogenesis, and hatching. |
| By the 20th day of gestation, the neural tube is formed and begins to close in the early stages of neurulation. |
