ABSTRACT
The aim of this research study was to determine the cephalic indices amongst the Urhobos in Delta State, Nigeria. Five hundred (500) subjects of ages 18-30 years were selected by random sampling in different villages for physical examination, all measurements were taken with the subject in a relaxed sitting position with the head in an anatomical position. The measured parameters were morphological f head length and breadth. The standard spreading caliper with scale was used for the measurement of cephalic parameters. The cephalic index was head breadth divided by the head length and multiplied by 100. The results showed that the total mean cephalic index was 76.86. Males had a cephalic index of 79.31, while females had a cephalic index of 93.60. Based on this study, 78.68% of individuals were mesocephalic, 11.4% dolichocephalic, 9.0% brachycephalic, 0.43% hyperbrachycephalic, This research showed that the urhobos are significantly mesocephalic and dolichocephalic. The obtained data in this study may be useful in anthropological and forensic research, medical and clinical practices (facial reconstruction).
Keywords: Anthropomentry, Urhobos, cephalic index, maximum head length, maximum head breadth, Cephalic phenotype.
