Abstract
The fertilized ovum reaches the uterine cavity in about 4 days as a morula of 12 to 16 cells. After developing a blastocoele and losing the zona pellucida, it implants on approximately the sixth day after conception. By the eighth day, the blastocyst consists of a chorionic membrane containing within it a bilaminar embryonic disk, separating the amniotic and yolk sac cavities. By the 11th or 12th day, the trophoblastic portion of the chorionic membrane shows clear-cut differentiation into cytotrophoblast, intermediate trophoblast, and syncytiotrophoblast.7
