||The blastocyst has an embryoblast, also called an inner cell mass, and a trophoectoderm or trophoblast layer. The 2 blastomere stage develops into the morula and at the formation of the blastocoel is then the blastocyst. The cavity lined by endoderm is the yolk sac and occurs after the blastocyst stage. The blastocyst stage occurs both before and after after hatching from the zona pellucida. | ||The blastocyst has an [[E#embryoblast|embryoblast]], also called an inner cell mass, and a [[T#trophoectoderm|trophoectoderm]] or trophoblast layer.
