This is a superb cross-sectional atlas of the human upper limbs. It is based on sectioned images with a pixel size of 0.06 mm from the Visible Korean dataset. The images are in 48-bit true color and cover nearly all bones, muscles with tendons, ligaments, vessels, and nerves in the limbs. In this atlas, the entire shapes and locations of these structures can be identified in the horizontal, coronal, and sagittal planes. This book offers detailed topographical knowledge of human anatomy. Furthermore, it serves as a valuable reference for radiology, aiding in the precise localization of small and complex structures as well as lesions.

Jin Seo PARK (Professor, Ph.D.) graduated from Ajou University School of Medicine in Republic of Korea. He is a professor at Department of Anatomy, Dongguk University School of Medicine in Republic of Korea. He is teaching and researching gross anatomy as a gross anatomist for twenty years. His main research is the Visible Korean Project in which the sectioned images with real color and high-resolution are made from cadavers and some animals. Using the sectioned Cross-Sectional Atlas of the Human Head: With 0.1-mm pixel size color images, he had published already three atlases in 2018, Cross-sectional Atlas of Rhesus Monkey Head: With 0.024-mm Pixel Size Color Images in 2022, and Cross-Sectional Atlas of Human Brainstem: With 0.06-mm Pixel Size Color Images in 2023.
