Structure K and Structure L are animations of which two stomach regions?

• A. Rugae and Pylorus
• B. Haustra and Fundus
• C. Incisura angularis and Pylorus
• D. Rugae and Incisura angularis

Answer: (B)

The question tests your ability to recognize stomach regions by their defining features. The stomach has identifiable parts such as the fundus, the dome-shaped upper region; the pylorus, the distal portion leading to the duodenum; and landmarks like the incisura angularis, a notch on the lesser curvature that helps mark the boundary between the body and the pyloric region. The inner lining forms rugae, folds that allow the stomach to expand, while haustra are sacculations found in the colon, not the stomach. When illustrating two stomach regions, the most straightforward pair to recognize would be the fundus and the pylorus, representing the top and the distal end of the stomach.
