Now, here is some of the formal terminology used in cell biology to refer to the micro-womb and micro-embryo.
The micro-embryo is called the “inner cell mass” (abbreviated “ICM”) or “embryoblast” or “pluriblast.”
The micro-womb before the inner cell mass appears is called a “morula.”
The micro-womb after the inner cell mass appears is called a “blastocyst.”
The subsurface part of the inner cell mass is called the “epiblast.”
Finally, upon closer examination, we see that the micro-embryo is actually a portion of the inner cell mass, not the entire inner cell mass. And, more specifically, the micro-embryo is actually a portion of the epiblast. In other words:
