From The Biology of Prenatal Development.Buy Now

Script: U razdoblju između 3. i 4. tjedna tijelo već poprima svoj oblik i mozak, leđna moždina i srce embrija se već jasno mogu razabrati unutar žumanjčane vreće.

Brzina rasta dovodi do savijanja još prilično spljoštenog embrija. U okviru tog procesa dio žumanjčane vreće razvija se u probavni sustav i dolazi do nastanka prsnog koša i trubušne šupljine nastajućeg živog bića.
