Development of embryos.Preface.

摘要

In the presented series of papers, the main focus lies in the illustrations of the development of embryos and embryonic organs. In our opinion, the form of an "atlas" is an appropriate way to illustrate step by step the normal development of organ systems that are of interest for pediatric surgeons. Whenever possible, illustrations of abnormal development are added. We believe that appropriate and illustrative findings in various fields of embryology are still lacking. This explains why today many typical malformations are still not explained satisfactorily. Thus, in this series of papers, scanning electron microscopy was used to illustrate embryonic development.
