Embryo with Placental Membranes
By the external appearance of the embryo appears to be about Week 7 (GA week 9) either Carnegie stage 18 or Carnegie stage 19
- amniotic sac - formed by the amniotic membrane (ectoderm and extra-embryonic mesoderm) completely surrounding the surrounding the embryo.
- yolk sac - the yolk membrane (endoderm and extra-embryonic mesoderm) attached to the embryo at the umbilicus and continuous with the midgut.
- chorionic cavity - has been removed but is represented by the black space outside the amniotic and yolk sac.
