Buy NowFrom The Biology of Prenatal Development.

Script: Do 3 až 4 dní po oplodnení zaujmú deliace sa bunky embrya guľovitý tvar a embryo sa teraz nazýva morula.

Do 4 až 5 dní sa v tomto zhluku buniek vytvorí dutina a embryo sa následne nazýva blastocysta.

Bunky vo vnútri blastocysty sa nazývajú vnútrobunková masa, z ktorej sa vyvinie hlava, telo a iné štruktúry, pre vyvíjajúceho sa človeka životne dôležité.

All ages referenced to fertilization, not last menstrual period.
