Expert Solution & Answer

Summary Introduction

To analyze:

The structures seen in the movie on time lapse of conceptus starting at day 3.

Introduction:

Upon conception, there are a series of events that follow one after the other from a unicellular zygote to multicellular embryo.

Explanation of Solution

In the video on the time-lapse of conceptus starting at day 3, the first structure seen is the morula. The morula is a ball of cells that resembles a berry. It is formed from repeated division of zygote to first form two blastomeres followed by more divisions to generate this ball of cells called morula.

The blastocoel first appears at a time elapse of 22 seconds of the video. At this point it is attached to the zona pellucida. At the end of the video the blastocoel 'hatches' from the matrix, that surrounds it. It can now head its way to implant into the walls of the uterus.

Conclusion

The morula divides to form the blastocoel that hatches out of the zona pellucida to implant into the uterus.
