From The Biology of Prenatal Development.Buy Now

Script: Acht weken betekent het einde van de embryonale fase.

Tijdens deze fase is het menselijk embryo gegroeid van één enkele cel tot bijna 1 miljard cellen die meer dan 4.000 verschillende anatomische structuren vormen.

Het embryo beschikt nu over meer dan 90% van de structuren die in volwassenen worden teruggevonden.

All ages referenced to fertilization, not last menstrual period.
