This series extracts the most important information on each topic and presents it in a concise, uncluttered fashion to prepare students for the USMLE. High-Yield means exactly that!

High-Yield Embryology, Fifth Edition provides a concentrated, efficient review of embryology material tested on the USMLE Step 1. Concepts are presented in a streamlined outline format with tables, diagrams, photos, and radiographs to clarify important material.

In response to student feedback, the Fifth Edition features:

New and updated figures
Additional USMLE-style case studies at the end of each chapter
An expanded section on early development
