Thoroughly revised and updated with the latest advances in human embryology, including the cellular and molecular basis of development, Before We Are Born: Essentials of Embryology and Birth Defects, 11th Edition, offers clinically relevant and highly illustrated coverage of this complex field. It is based on the popular text The Developing Human, written by the same expert and experienced educator author team. Coverage has been carefully selected to provide an easily accessible understanding of all the core aspects of embryology, including normal and abnormal embryogenesis, causes of birth defects, and the role of genes in human development.

Covers the essentials of normal and abnormal human development for students in a variety of health science disciplines, reflecting new research findings and current clinical practice through concise text and abundant, clearly labeled illustrations.
Offers authoritative, easily accessible, step-by-step coverage from conception through all stages of development to birth.
Features many new color photographs and new diagnostic images (3D ultrasound, CT, and MR images).
Includes an updated teratology section, revised and highlighted information on molecular aspects of developmental biology and genetics, and new information on the cellular and molecular basis of embryonic development.
Contains nearly 700 USMLE-style questions with full answers and explanations to help prepare for professional exams.
Includes clinical cases in every chapter that make important connections between human development and clinical practice-ideal for preparing for USMLE Step 1 and similar exams.
Provides access to 18 full-color, expertly narrated animations that guide students through key concepts of embryologic development.
Follows the official international list of embryological terms (Terminologia Embryonica, 2019).
An eBook version is included with purchase. The eBook allows you to access all of the text, figures and references, with the ability to search, customize your content, make notes and highlights, and have content read aloud.
