Stomach, Gross Anatomy, Brown

Description

Rising from the esophageal hiatus, the distal esophagus descends in the midline and expands into the stomach just inferior to the left hemidiaphragm. The gastric cardia and fundus sit superior and leftward, while the body sweeps inferomedially toward the pyloric antrum and pylorus, which track to the right and slightly inferior toward the proximal duodenum. Along the lateral border, the greater curvature arcs inferiorly, opposed by the shorter, more medial lesser curvature. A clear topographic map. Clinically, this oblique internal-through-surface presentation helps orient the stomach to palpable landmarks in the upper abdomen and lower thorax, which matters when correlating symptoms like epigastric pain or postprandial fullness with foregut anatomy. The relationship of the gastroesophageal junction to the diaphragmatic hiatus frames discussions of sliding hiatal hernia and gastroesophageal reflux disease, while the course from antrum to pylorus supports teaching around gastric outlet obstruction and the typical endoscopic route during EGD. The greater curvature emphasis also aligns with common operative corridors, including mobilization during sleeve gastrectomy and exposure of the gastroepiploic arcade. Use this asset in gross anatomy and gastrointestinal blocks to teach stomach regions and curvatures, in surgical education materials for bariatric and foregut procedures, or in patient-facing diagrams that need a realistic torso context without sacrificing organ position. It also suits textbook spreads on the upper GI tract where readers benefit from seeing the esophagus and stomach aligned in situ rather than isolated.
