Covering the essentials of normal and abnormal human development for students in a variety of health science disciplines, Before We Are Born: Essentials of Embryology and Birth Defects, 10th Edition, reflects new research findings and current clinical practice through concise text and abundant illustrations. This edition has been fully updated by the world's foremost embryologists and is based on the popular text, The Developing Human, written by the same author team. It provides an easily accessible understanding of all of the latest advances in embryology, including normal and abnormal embryogenesis, causes of birth defects, and the role of genes in human development. Features streamlined content throughout, numerous photographs of common clinical cases and embryological explanations, didactic illustrations, and nearly 700 USMLE-style questions with full answers and explanations to help prepare for professional exams. Includes interactive clinical cases in every chapter that make important connections between human development and clinical practice-ideal for preparing for USMLE Step 1. Features access to 18 full-color, expertly narrated animations that guide students through key concepts in learning the complexities of embryologic development. Includes many new color photographs, new diagnostic images (3D ultrasound, CT scans, and MR images), an updated teratology section, revised and highlighted information on molecular aspects of developmental biology, and new information on the cellular and molecular basis of embryonic development. Follows the official international list of embryological terms (Terminologia Embryonica, 2013). Enhanced eBook version included with purchase. Your enhanced eBook allows you to access all of the text, figures, and references from the book on a variety of devices.

Extensively revised to incorporate recent research and current clinical practice, The Developing Human: Clinically Oriented Embryology, 11th Edition, covers all aspects of normal and abnormal embryonic and fetal development. In a clear, concise manner and lavishly illustrated throughout, this textbook is designed to successfully meet the needs of medical and health sciences profession students, as well as those in graduate programs. It provides an easy-to-digest, comprehensive review of what can be a complex and challenging subject. BONUS online features such as multiple-choice questions and narrated animations further support student success. Guides readers month by month and stage by stage through embryo and fetal organ and systems development, using full-color photographs of clinical cases, relevant modern medical imaging, and numerous high-quality supportive figures. Includes many new 3D HD color rendered images of embryos and fetuses, as well as 3D reconstructions of whole embryos. Provides clinically-oriented problems for each chapter, with corresponding answers and explanations designed to facilitate discussion and learning. In addition, multiple-choice questions and answers are available online for supportive self-assessment. Features 18 exceptional color animations, now with narration, to help students as they explore and learn the complexity of embryological development. Provides the knowledge base needed for today's examinations, including USMLE Step 1, as well as for future clinical practice. Thoroughly updated information includes new annotations on fundamental molecular events during embryogenesis, now required for many professional examinations. Includes enhanced clinical material in all chapters, with updated tables, Clinical Case highlights and a critical chapter on common signalling pathways during development that covers gene editing (CRISPR/Cas9), induced pluripotent stem cells (iPS), a revision of the sonic hedgehog signalling pathway; and more. Details how molecular biology has affected clinical practice, including techniques such as recumbent DNA technology and stem cell manipulation. Includes an Enhanced eBook version with purchase. Your enhanced eBook allows you to access all of the text, figures, and references from the book on a variety of devices.
