- Germinal Stage (0-2 weeks): Fertilization, zygote formation, rapid cell division, and blastocyst implantation in uterus.
- Embryonic Stage (3-8 weeks): Critical period of organogenesis, forming all major organs and body systems.
- Germ layers (ectoderm, mesoderm, endoderm) differentiate during embryonic stage to form specific body structures.
