Gallbladder, Anterior View, Black

Description

Positioned in the right upper quadrant, the gallbladder (vesica fellea) appears as a pear-shaped biliary reservoir on the visceral surface of the liver, with its fundus projecting inferiorly toward the anterior abdominal wall. From an anterior perspective, the body lies superior to the transverse colon and lateral to the first part of the duodenum, while the neck angles medially toward the porta hepatis. The cystic duct courses from the neck to meet the common hepatic duct, forming the common bile duct that descends posterior to the proximal duodenum. Clear topography. Clinically, this anterior relationship matters because the fundus is the portion most likely to contact the parietal peritoneum and become tender in acute cholecystitis, producing a positive Murphy sign under the right costal margin. Gallstones often lodge at the gallbladder neck or cystic duct (Hartmann pouch region), and an inflamed, distended gallbladder can obscure Calot triangle landmarks during laparoscopic cholecystectomy, increasing the risk of common bile duct injury. A good anterior reference also helps orient ultrasound and CT correlation, where gallbladder wall thickening and pericholecystic fluid are key findings. Use this asset in gross anatomy and hepatobiliary teaching blocks to reinforce surface anatomy of the liver and biliary tree, or in surgical education materials illustrating cholecystitis, cholelithiasis, and cholecystectomy port placement in the anterior abdominal wall. It also fits clinical handouts and publisher figures discussing biliary pain patterns and right upper quadrant exam findings in adult male patients.
