Anatomical terminology

The angular incisure (or angular notch) is a small notch on the stomach. It is located on the lesser curvature of the stomach near the pyloric end. Its location varies depending on how distended the stomach is.[1]

The angular incisure is used as a separation point between the right and left portions of the stomach, the body and the pylorus.[2] An imaginary line drawn perpendicular to the lesser curvature of the stomach through the angular incisure makes up the boundary between the body of the stomach and pylorus.
