During the Flexion Phase, which cranial diameter increases?

Explanation:
In the Flexion Phase, the cranial bones move outward and the vault widens primarily in the transverse plane. The primary respiratory mechanism causes the parietal bones to spread laterally, so the skull becomes wider side-to-side. The anterior-posterior dimension does not increase in flexion (and may feel relatively shorter by comparison). So the transverse diameter is the one that increases during flexion.
