A series of analyses by the present author on the correlations between the neurocranium and individual vertebrae have shown that a few vertebral measurements are relatively highly correlated with cranial length or basi-bregmatic height. In this study, it was reconfirmed on the basis of male data that cranial length is associated with the sagittal and transverse diameters of the vertebral body throughout almost all vertebrae; and that basi-bregmatic height is also generally associated with the transverse diameter of the vertebral foramen. In addition, both male and female data on some representative measurements suggested that cranial length is associated also with the total transverse diameter of the atlas and with the sacral breadths at the upper and middle levels. For the causes of these associations, the possibility of the contribution from some ontogenetic and biomechanical factors was discussed.
