Quizplus · Accepted Answer

The inner cell mass is the functional area of the blastocyst that gives rise to the three primary germ layers: ectoderm, mesoderm, and endoderm. The amnion is a specialized membrane that surrounds the developing embryo and forms part of the amniotic sac. The morula is an earlier stage of embryonic development that precedes the blastocyst stage. The trophoblast is the outer layer of cells in the blastocyst that gives rise to the placenta.
