<Flowplayer height="400" width="360" autoplay="true">Human development 001.flv</Flowplayer> | 00:02 - Two blastomere cell stage: enclosed within the zona pellucida (pink ring) with polar bodies (upper right) lying under the zona pellucida.
00:06 - Morula stage: a solid ball of cells, still dividing rapidly. 00:08 - Blastocyst stage: trophoblast cells (at periphery), embryoblast (inner cell mass, right) and blastocoel (fluid-filled cavity, yellow) still within the zona pellucida. 00:09 - Blastocyst hatches from zona pellucida and adplants (attaches, adheres) to the uterine endometrium epithelium (right red structure) 00:10 - Bilaminar embryo stage: Embryoblast has formed two layers, hypoblast layer (yellow) and epiblast layer (blue). Amniotic cavity (fluid-filled space, blue beside the epiblast) forms, implantation continues into the uterine wall and the trophoblast layer now also forms two cellular layers (outer synctiotrophoblast and inner cytotrophoblast). |
