Script: U periodu između 3 i 4 sedmice tijelo već poprima svoj oblik, i mozak, kičmena moždina, i srce embriona se već jasno mogu razabrati unutar žumanjčane kese.

Brzina rasta dovodi do savijanja još prilično spljoštenog embriona. U okviru tog procesa dio žumanjčane kese se razvija u probavni sistem i dolazi do nastanka grudnog koša i trbušne šupljine nastajućeg živog bića.
