Stages of human embryonic development are: Zygote → Blastomere → Morula → Blastula (Blastocyst) → Gastrula → Neurula → Fetus.
Las etapas del desarrollo embrionario humano son: Cigoto → Blastomere → Mórula → Blástula (Blastocisto) → Gástrula → Nérula → Feto.

|---|---|
| Back | Zygote ↓ Blastomere (2 identical cells) ↓ Morula (a solid ball of small cells, same overall size as zygote, cells get smaller) ↓ Blastula aka Blastocyst in mammals (trophoblast & 20-30 inner cell mass) ↓ Gastrula ↓ Neurula ↓ Foetus |
