Mammals are hairy, but humans have shed most of it during evolution and became naked apes. Among humans men are supposed to be hairier than women. The hair pattern on the dorsal aspect of the hand is genetically and hormonally governed. This study has been conducted in Nigerians 1 and Indian Tribes. In association with the importance of this feature 124 subjects (63 males and 61 females) between the ages of 20 and 40 years were randomly selected from Medchal town, R. R. Dist, Telangana. The dorsal surface of the hands and digits of subjects was physically inspected for hair distribution. Observations were recorded and subdivided into gender and phalangeal hair patterns. Relation between gender and patterns was assessed by Fisher's exact test. Results show hair distribution patterns 1-2-3-4-5 (10%), 2-3-4-5 (54%), 2-3-4 (3%), 3-4-5 (16%), 3-4 (9%). One percent had no hair in there proximal phalanges. None of the females had hair on their middle phalanx. There was complete absence of hair on the distal phalanges. The pattern "3-4 "shows a significant female preponderance.
This study is conducted to know the various patterns of the human hand and digits. Anthropometric measurements were taken from 124 men and women, aged between 25 to 45 years in a factory in Ranga Reddy District, Telangana State. The data was analyzed by inferential statistics. The results have shown that various size factors are the principal source of variation in the hand size. Sexual dimorphism is predominantly seen in this study. Men have greater dimensional features with respect to women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
