Chorion 001 icon.jpg Facts: Week 1, size 0.1-0.2 mm Features: implantation completed, inner cell mass, bilaminar embryo, trophoblast development

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, the amniotic cavity.

blue - epiblast layer

yellow - hypoblast layer

red cells - extraembryonic mesoderm layer

green - trophoblast layer

red spaces - blood-filled spaces, maternal lacunae

white cells - (left) endometrial gland (right) endometrial epithelium
