Development Animation - Week 1: Difference between revisions

Revision as of 17:08, 7 August 2010

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.
