Script: Acht Wochen markieren das Ende der embryonalen Phase.

Während dieser Zeit ist der menschliche Embryo aus einer einzelnen Zelle zu annähernd 1 Milliarde Zellen herangewachsen, die über 4000 anatomische Strukturen bilden.

Der Embryo besitzt nun mehr als 90% der Strukturen, die man bei Erwachsenen findet.

All ages referenced to fertilization, not last menstrual period.
