. Anatomy of the woodchuck (Marmota monax). Woodchuck; Mammals. 94 Anatomy of the Woodchuck, Marmota monax. Fig. 5-11. Abdomen, deep ventral view. 1 left lateral liver lobe, 2 pyloric part of the stomach, 3 body of the stomach, 4 spleen, 5 left lobe of the pancreas, 6 left adrenal gland, 7 left kidney, 8 caudal duodenal flexure, 9 descending duo- denum, 10 right lobe of the pancreas, 1 1 right kidney, 12 cranial flexure of the duodenum, 13 quadrate liver lobe, 14 left medial liver lobe. right lateral and medial lobes. The caudate lobe presents papillary and caudate processes. Interlobar fissures separate the caudate and papillary process- es, as well as the left lateral and right lateral lobes, from each other and from the rest of the liver. The right medial, left medial and quadrate lobes are fused to a lesser or greater extent. The liver presents diaphragmatic and visceral surfaces and dorsal, ventral, left and right borders. The diaphragmatic surface, fades diaphragmatica, faces cranioventrally. It is strongly convex in all di- rections and lies against the diaphragm and the cra- nial part of the abdominal floor. The ligaments of the liver are attached to the diaphragmatic surface (see below). The visceral surface, fades visceralis, is irregularly concave, facing mainly caudodorsally and is in contact with various abdominal organs. Some parts of the liver lobes overlap each other, forming interlobar surfaces between the overlap- ping parts. All lobes of the liver, with the exception of the left medial lobe, contribute to the visceral surface. Various abdominal organs are in contact with the visceral surface, leaving their impressions that account in part for its irregular shape. The dor- sal border, margo dorsalis, and the left and right borders, margo sinister et dexter, lie within the rib cage and thus are not palpable. The ventral border, margo ventralis, projects beyond the costal arch and sternum by 4 to 5 cm and is palpable. The dorsal border is deeply groo
