Highly informative, this revised edition of Langman's Medical Embryology gives students a better understanding of the essentials of clinically relevant aspects of embryology. This Eighth Edition includes more information on the genetics of birth defects thus enabling the reader to go beyond morphology and understand embryogenesis at both the cellular and molecular levels. Clinical aspects are emphasized throughout the text, and clinically-oriented problems are listed at the end of each chapter with answers provided in the appendix. Fifty new three-dimensional illustrations help to enhance students' understanding of the organization and formation of the embryo at various stages. Many new SEMs, clinical photographs, and clearly labeled illustrations are incorporated throughout the text.
