About the Illustrator The illustrations throughout this book were carefully coordinated through a close collaborative effort between the author and artist. Every figure was custom developed specifically for this book, and refined to be medically accurate, precise, unique, and fresh. From a pedagogical point of view, it was important that all of the art be consistent throughout, rather than presenting a conglomeration of styles and levels of detail. Anita Impagliazzo is a medical illustrator and designer in Charlottesville, Virginia. A graduate of the University of Virginia, she went on to complete the Biomedical Illustration Graduate Program at the University of Texas Southwestern Medical Center at Dallas and spent several years specializing in illustrating for medical malpractice litigation. She has been self-employed since 2001, planning, creating, and collaborating on artwork for the University of Virginia Health System, for medical malpractice defense attorneys nationwide, and for multiple journals and textbooks (including the popular Martini Human Anatomy and Physiology series, and the revered Netter Collection of Medical Illustrations). She is a member of the Association of Medical Illustrators and has received several awards in its annual juried salons. She never tires of using medical language to learn new things about the human body: how it works, how it fails, how it is fixed, and how the fixing fails.
