Animation shows the events following implantation and focuses on changes in the the spaces surrounding the embryonic disc, the extraembryonic coelom.

The blastoceol cavity is converted into two separate spaces: the yolk sac and the chorionic cavity.

The third space lies above the epiblast layer of the embryonic disc, the amniotic cavity.


  • white cells - (left) endometrial gland (right) endometrial epithelium
  • blue - epiblast layer (forming ectoderm and amniotic cavity lining)
  • yellow - hypoblast layer (replaced with endoderm during gastrulation)
  • red cells - extraembryonic mesoderm layer
  • green - trophoblast layers (cytotrophoblast and syncitiotrophoblast)
  • red spaces - blood-filled spaces, maternal lacunae
