Stages of Embryonic Development Germinal Stage Details Fetal Stage of Development Lesson Summary Frequently Asked Questions What is the study of embryology? The study of embryology is the part of science that focuses on the early development during prenatal development. It covers everything that occur...
the new, single cell remains under the control of leftover proteins from the original egg cell. As the zygote begins to divide—first forming two cells, then four, and so on—to form an embryo, the residual maternal proteins dwindle. The embryonic cells, recognizing their waning resources, s...

From beginning as a one-cell structure to your birth, your prenatal development occurred in an orderly and delicate sequence. There are three stages of prenatal development: germinal, embryonic, and fetal. Let’s take a look at what happens to the developing baby in each of these stages. ...

The objective of this study was to determine if very early ultrasonographic measurements obtained from human and baboon are comparable. For this purpose, the gestational, amniotic and yolk sacs, embryonic crown rump length (CRL) and heart rate were measured ultrasonographically between 35 and 47 day...
