Quizplus · Accepted Answer

The embryonic stage is the stage of prenatal development when the heart begins to form and starts beating. This occurs around the 4th week of gestation. The germinal stage is the first stage, which lasts for about 2 weeks after conception, and is characterized by the formation of the zygote and its implantation in the uterus. The uterine stage is not a recognized stage of prenatal development. The fetal stage is the stage of development after the embryonic stage, where the fetus continues to develop and grow until birth.
