cleavage stages of embryonic development - Axtarish в Google
Cleavage encompasses multiple stages, including the development of the initial cleavage furrow in the zygote, or newly fertilized egg. The next stage is the morula, which has thirty-two blastomeres. The blastocyst then develops and the trophoblast and blastocoel are visible.
