Which feature is the incisura angularis?

Explanation:
Incisura angularis is the angular notch on the inner curve (lesser curvature) of the stomach. It marks the boundary between the body of the stomach and the pyloric portion (antrum) just before the stomach narrows toward the duodenum. That’s why this feature is identified as the incisura angularis. By contrast, rugae are the folds of the stomach lining, haustra are pouches seen in the colon, and the pylorus is the distal outlet of the stomach rather than a notch on the lesser curvature.
