Langman’s Medical Embryology 13th Edition
Every student will be affected by pregnancy, either their mother’s, because what happens in the womb does not necessarily stay in the womb, or by someone else’s. As health care professionals, you will often encounter women of childbearing age who may be pregnant, or you may have children o f your own, or maybe it is a friend who is pregnant. In any case, pregnancy and childbirth are relevant to all of us, and unfortunately, these processes often culminate in negative outcomes. For example, 50% o f all embryos are spontaneously aborted. Furthermore, prematurity and birth defects are the leading causes of infant mortality and major contributors to disabilities. Fortunately, new strategies can improve pregnancy outcomes, and health care professionals have a major role to play in implementing these initiatives.
However, a basic knowledge of embryology is essential to the success o f these strategies, and with this knowledge, every health care professional can play a role in providing healthier babies.
To accomplish its goal o f providing a basic understanding of embryology and its clinical relevance, Langm ans M edical Em bryology retains its unique approach of combining an economy of text with excellent diagrams and clinical images. It stresses the clinical importance of the subject by providing numerous clinical examples that result from abnormal embryological events.
The following pedagogic features and updates in the 13th edition help facilítate student learning.
Organization o f Material: Langm ans Medical Embryology is organized into two parts. The first provides an overview of early development from gametogenesis through the embryonic period.
Also included in this section are chapters on placental and fetal development as well as prenatal diagnosis and birth defects. The second part of the text provides a description of the fundamental processes of embryogenesis for each organ system.
Clinical Correlates: In addition to describing normal events, each chapter contains clinical correlates that appear in highlighted boxes. This material is designed to demónstrate the clinical relevance of embryology and the importance of understanding key developmental events as a first step to improving birth outcomes and having healthier babies. Clinical pictures and case descriptions are used to provide this Information, and this material has been increased and updated in this edition.
Genetics: Because of the increasingly important role of genetics and molecular biology in embryology and the study of birth defects, basic genetic and molecular principies are discussed.
The first chapter provides an introduction to molecular processes, defines terms commonly used in genetics and molecular biology, and describes key pathways used in embryonic development.
Then, throughout the text, major signaling pathways and genes that regúlate embryological development are identified and discussed.
