stomachgastricduodenum

Hand-painted in contrasting colors to accentuate subtle features, this anatomically-correct resilient vinyl replica splits into halves to access its hollow interior, convoluted rugae and pyloric valve. External details include the gastric artery, gastric nerve plexus, and dissections of the anterior stomach wall, at progressive depths, exposing its three muscular layers. The detachable molded display base incorporates the proximal portion of the duodenum, sectioned open, demonstrating its relationship to the stomach. The accompanying key identifies 17 features which have been hand numbered on the model. Esophagus. Food is carried from the mouth to the stomach by the Esophagus. Cardia. The Cardia (or “cardiac orifice”) is where the esophagus opens into the stomach. (Shown outside the stomach.) Fundus. The Fundus of the stomach is the dome-shaped portion above the Cardia (#516). Inside the body, it is located directly below the left dome of the diaphragm. Pylorus. The section of the stomach near the Pyloric Sphincter (409). Lesser Curvature. The upper, concave curve (margin) of the stomach. Greater Curvature. The outer, convex curve of the stomach. This curve is 4 or 5 times longer that the Lesser Curve (398). The groove identified by #400 is the attachment point of the Hepatogastric Ligament; which, when combined with the Hepatoduodenal Ligament, forms the Lesser Omentum. This groove can be seen running inside the entire Lesser Curva- ture of the stomach. A similar groove, found along the Greater Curvature of the stomach is the attachment point for the Greater Omentum.
