From The Biology of Prenatal Development.Buy Now

Script: Tarp 3 ir 4 savaitės pasirodo kūno struktūra, nes trynio maišelyje lengva atpažinti embriono smegenis, stuburo smegenis ir širdį.

Dėl spartaus augimo sąlyginai plokščias embrionas susilenkia. Šio proceso metu dalis trynio maišelio prisijungia prie virškinimo sistemos sienelės ir suformuoja besivystančio žmogaus krūtinės ląstą ir pilvo ertmes.

4 SAVAITĖS

All ages referenced to fertilization, not last menstrual period.
