Quizplus · Accepted Answer

The egg is fertilized during the germinal period, which is the first stage of prenatal development. During this time, the fertilized egg goes through several cell divisions and eventually forms a blastocyst, which then implants in the wall of the uterus. The embryonic period follows the germinal period and lasts from weeks 3-8, during which time the major organs and systems of the body begin to develop. The fetal period begins at week 9 and lasts until birth, during which time the fetus continues to grow and mature.
