Midline cranial bones move with which type of motion?

Explanation:
Midline cranial bones move with flexion and extension as part of the primary respiratory mechanism. They act as a unit around a transverse axis, producing a rhythmic motion that accompanies breathing. This differs from the movements of the paired bones, which are more involved with torsion and side-bending/rotation. So the expected, physiologic motion of these midline structures is flexion/extension.
