This book was amazing for helping me actually learn the structures for Anatomy and Physiology I. I recommend using this book while you are learning the structures in lab. It helps it stick in your brain, and it makes learning fun. I even found myself during the lab exam remembering the colors I used for that particular structure. One thing I also like is they give you a little study outline for the page you are about to color, detailing what they do. It was the best money I could have spent to help me pass lab this Summer!
