BRS Embryology

BRS Embryology, Fifth Edition is a succinct outline-format review for USMLE and course exams, with review questions at the end of each chapter and a comprehensive USMLE-style examination at the end of the book. The text outlines the important facts and concepts tested on the USMLE, within the context of human embryologic development. The book also includes radiographs, sonograms, computed tomography scans, and photographs of various congenital malformations.

This edition has been updated and includes new, additional USMLE-style questions. Clinical images have been placed closer to the relevant text. The BRS for Embryology is a supplemental text that is incredibly helpful. The book helps to make even the most confusing development stages easy to understand and learn. It helps to weed through the details and focus on the main concepts.

A companion website offers the fully searchable text and an interactive question bank.
