Dermatoglyphics Dermatoglyphics has a rich and scientific history of over years and has documentation of research data and results dated years back. Harold Cummins is acknowledged as the Father of Dermatoglyphics.
Sensory The radial nerve supplies the skin on the back of the hand from the thumb to the ring finger and the dorsal aspects of the index, middle, and half ring fingers as far as the proximal interphalangeal joints.
The median nerve supplies the palmar side of the thumb, index, middle, and half ring fingers. Dorsal branches innervates the distal phalanges of the index, middle, and half ring fingers.
The ulnar nerve supplies the ulnar third of the hand, both at the palm and the back of the hand, and the little and half ring fingers. For example, in some individuals, the ulnar nerve supplies the entire ring finger and the ulnar side of the middle finger, whilst, in others, the median nerve supplies the entire ring finger.
Indeed, genes specifically expressed in the dermis of palmoplantar skin inhibit melanin production and thus the ability to tanand promote the thickening of the stratum lucidum and stratum corneum layers of the epidermis. All parts of the skin involved in grasping are covered by papillary ridges fingerprints acting as friction pads.
In contrast, the hairy skin on the dorsal side is thin, soft, and pliable, so that the skin can recoil when the fingers are stretched. These webs, located between each set of digits, are known as skin folds interdigital folds or plica interdigitalis.
They are defined as "one of the folds of skin, or rudimentary web, between the fingers and toes".
Digit ratio The ratio of the length of the index finger to the length of the ring finger in adults is affected by the level of exposure to male sex hormones of the embryo in utero. This digit ratio is below 1 for both sexes but it is lower in males than in females on average.
Clinical significance[ edit ] X-ray of the left hand of a ten-year-old boy with polydactyly. A number of genetic disorders affect the hand. Polydactyly is the presence of more than the usual number of fingers.
One of the disorders that can cause this is Catel-Manzke syndrome.
The fingers may be fused in a disorder known as syndactyly. Or there may be an absence of one or more central fingers—a condition known as ectrodactyly. Additionally, some people are born without one or both hands amelia. There are several cutaneous conditions that can affect the hand including the nails.
The autoimmune disease rheumatoid arthritis can affect the hand, particularly the joints of the fingers. Some conditions can be treated by hand surgery. A similar condition[ clarification needed ] to this is where some of the fingers cannot be flexed due to injury to the ulnar nerve.
A common fracture of the hand is a scaphoid fracture —a fracture of the scaphoid boneone of the carpal bones. This is the commonest carpal bone fracture and can be slow to heal due to a limited blood flow to the bone.This research aims to assess the reports generated from the Dermatoglyphics Multiple Intelligence Test (DMIT) administered by selected DMIT resource companies and consultancy firms in India with the end view of identifying its implication to career.
Background: Dermatoglyphic patterns, share their development time during the intrauterine period, with the development and completion of dental hard tissues. Being related by origin, the association has also been thought to be present in factors affecting and influencing dental structures, to have an effect on the dermal ridges.
Malocclusion, a dental disorder, with its genetic etiology being. Dermatoglyphics has a rich and scientific history of over years and has documentation of research data and results dated years back.

The Lucky Mojo Curio Company was founded in the belief that there is a strong need in the community for knowledge about traditional Southern-style hoodoo and . Abstract. In Chapter I, the subject of dermatoglyphics was introduced, and the aims of the present study outlined: to establish the range of local variation of various dermatoglyphic traits in the South Wales Coalfield and surrounding areas.
