Duodenum, Gallbladder, and Pancreas, Anterior View

Description

Centered in the upper abdomen, the C-shaped duodenum curves from right to left around the head of the pancreas, then continues as the jejunum distally at the duodenojejunal flexure. The elongated pancreas spans transversely, with its head nestled in the duodenal concavity and its body extending leftward, placing the pancreatic tissue posterior to the anterior duodenal wall in this anterior perspective. Superior and slightly to the right, the gallbladder sits as a pear-shaped sac, its neck tapering into the cystic duct, which joins the common hepatic duct to form the common bile duct before descending toward the second part of the duodenum. Fine branching lines track along the hepatopancreatic region, consistent with autonomic nerve pathways traveling with the celiac and superior mesenteric plexuses. Anterior anatomy in this region matters because surgical and endoscopic access often follows these surface relationships. The convergence of the common bile duct and main pancreatic duct at the major duodenal papilla explains why an impacted gallstone can trigger acute pancreatitis, and it also clarifies the target anatomy for ERCP and sphincterotomy. Small space, high stakes. Use this plate for teaching foregut and midgut junction anatomy in gross anatomy, GI blocks, or hepatobiliary modules, and for illustrating discussions of choledocholithiasis, obstructive jaundice, pancreatic head carcinoma, and the pathway of referred pain mediated by splanchnic nerves. It also fits well in operative and endoscopy primers that need a clean anterior map of the duodenum, biliary tree, and pancreas. Anatomical accuracy verified by SciePro's Medical Advisory Board.
