This volume presents the field of embryology with the assistance of colour plates. Since the information relevant to medical students is separated from that needed by biologists, both can learn in a focused and time-saving manner. The overview at the beginning of each chapter should be a useful aid to students. Interested readers - medicine, biology, dentistry, biochemistry - can delve into topics, ranging from the basics of reproductive biology to general embryology, including the "hot topics" related to cellular and molecular biology. The 176 colour plates start with overview charts at the beginning of each chapter. Standard colour coding on charts is used throughout. Each page of textual explanation is jusxtaposed to a corresponding chart. The contents are divided into chapters addressed to medical students or biology students, or both, allowing each group to focus on the information they require. This "Flexibook" may be used as a textbook by all medical and biology students to get them through this part of their basic training.
