Gallbladder, Duodenum, and Pancreas, Anterior View

Description

Anteriorly, the pancreas sits retroperitoneally across the upper abdomen, its head nestled within the C-shaped duodenum on the right side of the image and its body extending leftward toward the splenic region, with the tail tapering laterally. Superior and slightly anterior to the duodenal bulb, the gallbladder lies on the visceral surface of the liver and funnels inferiorly into the cystic duct, which joins the common hepatic duct to form the common bile duct descending toward the second part of the duodenum. A transparent, x-ray style ribcage and vertebral column frame these relationships, while green nerve elements course around the pancreatic region, consistent with the celiac plexus and peripancreatic autonomic fibers. Clean orientation. That duodenal loop around the pancreatic head is more than a teaching trope, it explains why edema or a mass in the head of the pancreas can narrow the second portion of the duodenum and why inflammation can track along the peripancreatic planes. The extrahepatic biliary tract entering the medial wall of the descending duodenum at the major duodenal papilla is a key landmark in ERCP and in understanding obstructive jaundice from choledocholithiasis or pancreatic head carcinoma, where the common bile duct often dilates upstream. The nerve depiction supports discussion of visceral pain referral patterns and the rationale for celiac plexus block in pancreatic cancer pain. Use this plate in gross anatomy and GI modules to anchor spatial reasoning: where the gallbladder and biliary tree sit relative to the duodenum, and how the pancreas spans the midline behind the stomach. It also fits surgical and endoscopy teaching materials covering cholecystitis, choledocholithiasis, pancreatitis, pancreaticoduodenectomy (Whipple) anatomy, and radiology primers that benefit from an x-ray style context against the ribcage and spine.
