Palate bones - The pyramidal process should move externally, inferior and posterior

maxilla:

External rotation should take place around two vertical axis along the frontal processes. The posterior portions of the alveolar processus get wider, the inter-maxillary suture moves posterior. The palate plate sinks.

 Intraosseous adaptation of the maxilla to a global expansion and retraction of the skull.

Palate bones:

The palate plate lowers itself. The pyramidal process should move externally, inferior and posterior. The palate bone is also referred to as a speed reducer, since it mediates between the cranial base and the maxilla.

The nasal bones perform an external rotation.

The lacrimal bones perform an external rotation.
