The Morula and Blastocyst


5 days

From The Biology of Prenatal Development.Buy Now

Script: Innen 3 til 4 dager etter befruktning, cellene i embryoet tar en kule - form når de deler seg og embryoet kalles en morula.

Innen 4 til 5 dager dannes et hulrom i denne celleklumpen og embryoet kalles nå for en blastocyst.

Cellene i blastocysten heter kimskiven - den indre cellemassen, som skal forme hode, kropp, og andre livsviktig organer til det voksende menneske.

All ages referenced to fertilization, not last menstrual period.
