Abstract:
Cranial capacity is a measure of the volume of the interior of the cranium which is sometimes used as a rough indicator of the size of the brain and is mostly affected by environmental, geographical, gender, age, nutritional and racial factors. A survey of available literature indicates a lack of study on cranial capacities in adults resident in Maiduguri North Eastern Nigeria, this study was therefore undertaken to determine the Cranial Capacities (CC) of 300 (150 males, 150 females) aged 18-35 years adults resident in Maiduguri Metropolis using a random stratified method. Linear measurements of cranial length, width, height and head circumference were undertaken and their cranial capacities calculated. The Mean (±SD) of cranial capacity was significantly (p<0.0001) higher in males (1424.4±137.9) than in females (1331.3±201.8). Cranial length and height were also found to be significantly higher in males than in females. The results obtained from this study confirms that the cranial volume of males is higher than that of the females and also suggest that the cranial capacity of adult males and females were slightly higher than those of similar studies carried out in some ethnic groups indigenous to the southern part of Nigeria.
