The embryoblast is the inner cell mass of the pre-embryo that gives rise to the developing embryo. The trophoblast, cytotrophoblast, and syncytiotrophoblast are all involved in the formation of the placenta and other extraembryonic membranes, but do not give rise to the embryo itself. The morula is an earlier stage of development before the pre-embryo undergoes compaction and forms distinct inner and outer cell masses.
