For the latest information about embryological development, turn to HUMAN EMBRYOLOGY AND DEVELOPMENTAL BIOLOGY. This comprehensive, clearly written textbook emphasizes the molecular basis of human embryological development, explaining the "why" in addition to the "how." Many full-color clinical photographs and illustrations stress the function of embryological structures and the progression of development. All information has been updated to include the most current research findings and contemporary clinical applications. Chapter summaries and review questions aid in students' learning. This edition includes new clinical photographs, Clinical Correlation boxes, and clinical vignettes. Discusses development in terms of activity at the molecular and cellular level to explain embryological development, instead of just describing structure and function. Includes over 300 color drawings in striking detail, drawn in accordance with the universally-accepted embryological color code for more realistic representation. Contains end-of-chapter questions to provide quick review of the most important concepts for better comprehension. Features chapter summaries of the key concepts to reinforce comprehension and encourage student self-assessment. Uses boldface key terms to emphasize the terms and concepts that students most need to know. Features a clear, concise, understandable narrative that focuses on the progression of development to provide easy comprehension of difficult and complex material. Provides many full color photographs of clinical conditions. Spanish version also available, ISBN: 84-8174-471-9
