The fetal period of human growth and development has become an area of intense study in recent years, due in large part to the development of diagnostic ultrasound. More than 2,000 articles have been published in the last five years describing anatomy and pathology in utero, as reflected in sonographic images. Yet, no stan dard reference exists to correlate these images with fetal gross anatomy and at tempts to draw parallels from adult structure have often led to false assumptions. The dictum "the newborn is not a miniature adult" is all the more valid for the fetus. This text aims to provide a comprehensive reference for normal sectional anat omy correlated with in utero ultrasound images. In addition, magnetic resonance images of therapeutically aborted or stillborn fetuses are paired with similar gross sections to serve as a foundation upon which current in vivo studies may build. Lastly, a miscellaneous section illustrates several anatomic points useful in the understanding of fetal anatomy. These points include the changing anatomy of the fetal brain during gestation and the anatomy of the meninges, the fetal heart, and ductus venosus. It is our hope that this atlas will provide a clear picture of fetal anatomy, rectify some of the confusion which exists in antenatal diagnosis, and stimulate further interest in fetal development."

The need for accurate information about the anatomy of the newborn infant led to the publication in 1968 of Dr. Crelin's large and detailed atlas, the first of its kind. The present volume is a synopsis of that atlas. Professionals and paraprofessionals who deal with the newborn will find it a highly useful and convenient reference. Since the newborn infant is not a miniature adult, those parts of the infant's functional anatomy that differ most from the adult receive the greatest emphasis. Each structure is discussed in a separate section that includes, where pertinent, the time during prenatal development or after birth that the structure first appears and/or functions. Clinically important information such as pulse rate, blood pressure, blood cell counts, body temperature, and breathing rate is also included. The three full-page plates of the whole body have general clinical application since they make it possible to relate internal body parts to the surface of the body of the newborn infant. This concise volume will be of great value to obstetricians, pediatricians, surgeons, anesthesiologists, radiologists, pathologists, family physicians, and nurses. The work is unique and represents Dr. Crelin's twenty years of experience in teaching anatomy and as a consultant to the Newborn Special Care Unit of the Yale-New Haven Medical Center.
