The Nine Abdominal Regions and Surface Planes in Human Anatomy
This concept covers the surface anatomy of the abdomen, specifically how vertical (midclavicular) and horizontal (subcostal and transtubercular) reference planes divide the anterior abdominal wall into nine defined regions. The core principle is that these regions correspond to the deep positions of specific abdominal organs, so surface localization of pain or findings can be used to infer which underlying structure is involved, a foundational tool in topographic anatomy and clinical localization.
