During cranial flexion, what happens to the anterior-posterior diameter?

Explanation:
In cranial flexion the skull shortens front-to-back as the sphenoid and occiput rotate about the sphenobasilar synchondrosis and move closer along the anterior-posterior axis. This brings the midline bones toward each other, reducing the anterior-posterior diameter. The opposite happens in extension, where the AP diameter lengthens. A helpful cue is that flexion tends to increase transverse width while shortening the AP span.
