Estimation Of The Cranial Capacity In Dry Human Skull Bones

ABSTRACT

Introduction: Cranial capacity is a measure of the volume of the interior of the skull of those vertebrates whohave both a skull and a brain. Cranial capacity is used as a rough indicator of the size of brain. Cranialcapacities like several bodily dimensions are affected by environmental, ecological, biological, geographical,racial, gender and age factors. Aim: The aim of the study is to measure and calculate cranial capacity by direct and calculated methods andto classify the skull under different subtypes.Materials and Methods: The study will constitute 100 dried human skull bones belonging to both sexes in theDepartment of Anatomy, Rajarajeswari medical college, Bengaluru.Results: The average cranial capacity by using direct method is 1275.33cc ± 124.68cc in male skulls and 1213cc± 138.66cc in female skulls and by calculated method is 1344.10cc ± 106.62 cc in male skulls and 1276.26cc ±68.72cc in female skulls respectively.Conclusion: The mean cranial capacities of male skulls were higher than that of female skulls that tends to agreewith similar studies conducted earlier. Thus, the cranial capacity of the male skulls is 5-15% higher than thefemale skulls
