During the Flexion Phase, the vomer moves in which direction?

• A. Superiorly
• B. Inferiorly
• C. Laterally
• D. Medially

Answer: (B)

During the Flexion Phase, the cranial base rotates so that midline structures move downward. The sphenoid tilts anteriorly and inferiorly while the occiput tilts posteriorly and superiorly, and the vomer, linked to the nasal septum, follows this downward shift. So the vomer moves in an inferior direction. Extension would reverse this motion, with the vomer moving superiorly. Lateral or medial movement isn’t the primary direction for the vomer in these phase changes.
