Medial Division of the Right Liver, Inferior View

Description

Oriented from an inferior perspective, the medial division of the anatomical right lobe of the liver is isolated, with the visceral (inferior) surface facing the viewer and the diaphragmatic surface directed superiorly. Expect the gallbladder fossa to lie anteroinferiorly on this surface, with the porta hepatis running transversely and separating the caudate process region posteriorly from the quadrate lobe region anteromedially. Medially, the fissure for the ligamentum teres and the groove for the ligamentum venosum define the boundary toward the anatomical left lobe, while the inferior vena cava impression sits posteriorly near the caudate lobe. Clinically, this cut of anatomy maps cleanly onto segmental liver teaching, because the medial division of the right liver corresponds to Couinaud segment V (and adjacent segment VIII superiorly), separated functionally by the course of the middle hepatic vein and portal pedicles rather than by external lobar landmarks. Surgeons planning a cholecystectomy, a segment V wedge resection, or a right anterior sectionectomy look for the relationship between the gallbladder bed, the hepatic hilum, and the plane of the main lobar fissure to avoid bile duct injury and to control inflow at the porta hepatis. A tight, inferior view makes those surface cues easier to teach. Use this illustration in hepatobiliary surgery lectures, anatomy lab manuals covering the visceral surface of the hepar, and publisher figures explaining Couinaud segments and the porta hepatis in male anatomy references. It also suits patient-facing education on gallbladder surgery when you need accurate spatial orientation without surrounding abdominal viscera.
