ABSTRACT

123 male subjects, who are students of Bowen University, within the age range of 15-30 years, were chosen randomly for the study of the pattern of phalangeal hair distribution on the proximal, middle and distal phalanges of the hands, with 150 male subjects selected to study the pattern on the foot. For the females, 148 subjects, who are students of Bowen University, within the age range of 15-30 years, were chosen randomly for the study on the hands, while 150 subjects were studied for the phalangeal hair patterns on the foot. All subjects were from various tribes in Nigeria. It was discovered through the study that in males, the most prominent pattern on the proximal phalanges of the hand was 2-3-4-5, with hair present on 98% of the subjects. In females, the most prominent pattern on the proximal phalanges of the hand was 2-3-4-5, with hair present on 92.2% of the subjects. For the pattern of phalangeal hair on the middle phalanges of the hand, the most prominent pattern in males were those without hair, and for those with hair, the most prominent pattern was the 4 pattern, while in females, the most prominent pattern were those without hair, and those with hair had their most prominent pattern as the 4 pattern. For the pattern of phalangeal hair on the distal phalanges of the hand, in males, the most prominent pattern were those without hair (100%) and in females, they were also those without hair (95.5%) but 4.5% of the female subjects had hair with the 1 pattern. For the foot, in males, the most prominent pattern on the proximal phalanges was 2-3-4-5, with hair present on 81.3% of the subjects. In females, the most prominent pattern on the proximal phalanges was those without hair (31.3%), with those with hair having the prominent pattern as 1-2-3-4-5 (17.3%). For the pattern of phalangeal hair on the middle phalanges, the most prominent pattern in males were those without hair (98.6%), and for those with hair, the most prominent pattern was the 2 pattern (1%), while in females, the most prominent pattern were those without hair (94%), and those with hair had their most prominent pattern as the 1 pattern (3.6%). For the pattern of phalangeal hair on the distal phalanges, in males, the most prominent pattern were those without hair (99.6%), those with hair had the most prominent pattern as the 1 pattern (0.8%) and in females, the most prominent were those without hair (95.5%) but 4.3% of the subjects had hair with the 1 pattern. The patterns were recorded and analysed using descriptive statistics and the data were group based on the hand observed (left or right), the sex (male or female) and the major tribes which the subjects belonged to. The patterns of phalangeal hair distribution from the study indicate regional and sexual variations and also show similarities within and among various race, language and nationality.
