During cranial extension, the vomer moves in which direction?

During cranial extension, the vomer moves in which direction?

• A. Superiorly
• B. Inferiorly
• C. Anteriorly
• D. Posteriorly

Answer: (A)

During cranial extension, the midline nasal structures move upward as part of the coordinated cranial rhythmic mechanism. The vomer, as part of the nasal septum and connected to surrounding bones like the sphenoid, follows this upward glide when extension occurs. This cephalad shift reflects the pattern of extension where midline structures are carried toward the superior aspect of the skull. Moving in anterior, posterior, or inferior directions would not fit the observed up-and-back/cephalad pattern of extension, making superior movement the correct direction.
