Stomach, Brown

Description

Centered in the upper abdomen, the ventriculus (stomach) sits inferior to the diaphragm and left lobe of the liver, continuous superiorly with the abdominal esophagus at the cardia and tapering distally toward the pylorus. The gastric fundus rises superior and left of the gastroesophageal junction, while the body curves inferomedially toward the antrum along the lesser curvature, with the greater curvature sweeping inferiorly and laterally. Superficial muscle contours of the gastric wall are emphasized, suggesting the underlying layers (longitudinal, circular, and oblique fibers) that shape the gastric pouch. Other external body landmarks remain visible in anatomical position for orientation. Clear emphasis on the esophagus to stomach pathway supports teaching of gastroesophageal anatomy and anti-reflux mechanisms at the lower esophageal sphincter and diaphragmatic hiatus. Orientation matters. This anterior-style whole-body context helps clinicians and students correlate symptoms such as dysphagia, gastroesophageal reflux disease, and hiatal hernia with the location of the cardia and fundus, and it also frames where endoscopic landmarks are encountered when passing from esophagus into the gastric lumen. Use this illustration in preclinical gross anatomy and gastrointestinal physiology modules to anchor discussions of gastric motility and regional terminology (fundus, body, antrum, pylorus), or in patient-facing education explaining where swallowed material travels before digestion begins. It also suits textbooks and slide decks covering upper endoscopy, bariatric surgery concepts involving the gastric pouch, or abdominal pain localization in the epigastrium and left upper quadrant.
