With more than 300 medical illustrations plus schematics, tables, and concise text, this is the only atlas with comprehensive coverage of the major processes, events, and concepts related to normal and abnormal embryonic development. Emphasizing the morphological patterns in the embryo and fetus, the development of the embryo is placed in a context that makes it easier to understand the structure and function of the adult body and the embryonic basis of congenital birth defects. It includes an introduction to histological principles, the classification of congenital defects, and basic cellular, molecular, and genetic concepts such as induction, apoptosis, growth factors, and genetic patterning and determination.
