Male Skeleton Showing the Stomach and Hiatal Hernia Underneath

Description

Rotating skeletal anatomy frames the upper abdomen while a sectional stomach sits inferior to the left hemidiaphragm, with the esophagus descending through the esophageal hiatus to the gastroesophageal junction at the cardia. During the sequence, the herniated gastric cardia and proximal fundus migrate superiorly through the diaphragmatic opening, illustrating a hiatal hernia as a true displacement rather than a simple bulge. Ribs, lower thoracic vertebrae, and costal margins provide fixed bony landmarks as the stomach’s rugae and mucosal surface appear in cutaway beneath. Orientation is clear. Clinically, this is the anatomy behind reflux. When the gastroesophageal junction slides above the diaphragm, the anti-reflux barrier created by the crural diaphragm and the angle of His loses its mechanical advantage, correlating with gastroesophageal reflux disease, esophagitis, and, over time, Barrett metaplasia. Animated cranial and caudal motion across the hiatus clarifies what static radiographs and endoscopic photos only imply, and it helps separate the concept of a sliding hiatal hernia from a paraesophageal component where the fundus can remain intrathoracic with risk of obstruction or gastric volvulus. Use it in gross anatomy labs to teach diaphragm and foregut relationships, in GI and thoracic surgery talks when introducing hiatus dissection and fundoplication planning, and in radiology or gastroenterology education alongside barium swallow and endoscopy correlations.
