Flexed cranial base
WebFeb 18, 2015 · Cranial base and face are already correlated early in ontogeny, and the relationship between these modules gains structure through postnatal growth and development. These results provide further … Webskull. Two of the more noteworthy of these changes are the increase in endo-cranial capacity, and the flexion of the cranial base as measured by the sphenoidal angle. Sinanthropus pekinensis and Solo man, for example, differ from the nonhuman anthropoids in having larger brain cases and more flexed cranial bases (among other things).
