Talk:Blastula
From Wikipedia, the free encyclopedia
is the blastula the same as the blastocyst? if so, should be merged.
found somewhere that the blastula follows the morula stage (16cell) during which for about 3 days mitotic divisions continue, but differentiation between the embryoblast and trophoblast has not yet occurred. This should be confirmed though. However, several embryology texts note that once the cavity has formed it is considered a blastocyst. Might be an unnecessary delineation.
