This animation summarises early development in the first week following fertilization.
The conceptus proceeds through embryonic cell cycle rounds of mitosis still enclosed within the zona pellucida. Progressing from a zygote, to blastomeres, then to a morula and finally to a blastocyst.
The uterine tube epithelium consists of ciliated cells that are moving the secreted fluid towards the uterine body. The conceptus is floating "boat-like" within this fluid and moved in the same direction.
Towards the end of the first week the blastocyst has reached the uterine body and after about day 5 onwards, the blastocyst "hatches" from the surrounding zona pellucida.
