As a step toward clarifying the causes and mechanism of brachycephalization, correlations between neurocranial and leg bone measurements were examined by principal component analysis and Kaiser's normal varimax rotation methods. The results based on modern Japanese skeletons show that, while cranial breadth has no systematic association with any measurements of the patella, tibia or fibula, cranial length is strongly associated with tibial length and thickness in both sexes and with fibular length and thickness only in males. These, together with previous findings, suggest that the general development of skeletal muscles such as nuchal muscles and those attached on the extremity bones is considerably concerned with the variation of cranial length, and that the affection of such muscle development on the associations between cranial length and limb bone measurements may be more definitely expressed in males than in females because muscles are generally more developed in males.
