![]() ![]() Results show that bun morphology, when present, develops very early in childhood. Partial least squares analysis (PLS) was performed to assess patterns of correlation between occipital bone shape and other aspects of cranial midline morphology. Measured individuals represent the extremes of adult variation in occipital squama convexity in both males (n=12) and females (n=4). ![]() Landmarks and sliding semi-landmarks were measured from lateral radiographs in individuals spanning 3.0 to 19.8 years of age. This study assesses the developmental timing of occipital bunning in the Burlington Growth Centre longitudinal craniofacial growth study. The influence of overall neurocranial profile size and shape, as well as other factors such as cranial base flexion variability on occipital bunning, however, has never been quantitatively studied from a developmental perspective. Because its functional significance has yet to be definitively determined, some authors suggest that the occipital bun develops as a by-product of forces working elsewhere in the cranium. ![]() " Occipital bunning, the distinctive posterior projection of the occipital squama found in Neandertals and some anatomically modern humans, is a commonly cited but poorly understood anatomical feature. ![]()
