After rotation, which curvature moves to the right?

After rotation, which curvature moves to the right?

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

Answer: (C)

The stomach reorients itself during development by a 90-degree clockwise rotation on its long axis. This twist places the left side forward (anterior) and the right side backward (posterior). The border that becomes the lesser curvature is the right/medial border, so as the stomach twists, that border shifts to face the right side of the abdomen. In other words, the lesser curvature ends up on the right. The greater curvature, forming the left and inferior border, moves to the left.
