High-Yield™ Embryology, Fourth Edition provides a concise, focused review of the most important embryology information
needed for the USMLE Step 1. Chapters cover prefertilization events and the embryonic period, embryologic development
of each organ system, chromosomal abnormalities, inherited diseases, teratology and more. To prepare students for the
clinical vignettes on the USMLE, the book includes numerous clinical cases with words and phrases that patients
use.This edition also features new placement of clinical images within the chapter for clearer understanding.
