Sexual Dimorphism in Endocranial Capacity of Dry Human Skulls in Central India Region
Main Article Content
Abstract
Cranial capacity is indicative of brain volume and is important for deciding racial and sexual characteristics in physical anthropological studies. It is measured both directly by filling the cranial cavity with various materials like lead shots, mustard, cast materials etc and indirectly by using derivation formulae. In the present study, volume of the cranial cavity is measured by using mustard seeds and calibrated glass cylinder. The range of cranial capacity is 1120- 1650 cc and 800-1280 cc in male and female skulls respectively. Cranial Capacity was statistically significant, t (258) = -16.94, p = <.001, 95% confidence interval [-203.13, 160.6] it is an important measured parameter to differentiate male and female skulls. The results are useful for anatomists, medicolegal experts and anthropologists.
