Which curvature moves to the left after rotation?

• A. Lesser curvature moves to the left
• B. Anterior curvature moves to the left
• C. Greater curvature moves to the left
• D. Posterior curvature moves to the left

Answer: (C)

During development the stomach twists 90 degrees clockwise around its long axis. This rotation reorients the organ so that the left side faces anteriorly and the right side faces posteriorly. The greater curvature forms the left, outer border of the stomach, while the lesser curvature forms the right, inner border. Because of this clockwise rotation, the greater curvature moves to the left side of the abdomen and becomes the prominent left border, whereas the lesser curvature shifts toward the right. So the curvature that ends up on the left after rotation is the greater curvature.
