During the Flexion Phase, what happens to the anterior-posterior diameter of the cranium?

Explanation:
During the Flexion Phase, the cranial bones move toward one another along the front-to-back axis, shortening the skull in the anterior-posterior direction. In this phase the sphenoid and occipital bases approximate, so the distance from the front to the back of the skull decreases. The opposite occurs in extension, where the AP diameter lengthens.
