Lines in the palms of the hands

Why we have lines in the palms of the hands?

Scientifically, the skin folds on the palm are called palmar flexion creases, which are formed while we are in the uterus around the third month of pregnancy and have a very specific function: skin stretching and contraction.

Most people have three lines on the palm, although their thickness and number also depend on genetic inheritance and race.

Those who only have one line, named simian, an anomaly found in one out of thirty people, especially in men, can show problems of motor and cognitive development that are associated to some disorders such as Down syndrome, cat meow or Klinefeller's syndrome (a genetic disorder in which a male is born with an extra X chromosome), Aarskog (related to the X chromosome and usually affects men by a mutation in the FGD1 gene.), Turner (genetic disorder producing a lack of X chromosome or part of it in the cells), Cohen (a rare developmental genetic disorder characterized by microcephaly), fetal alcoholism (appears in the fetus when the mother consumes alcohol during pregnancy), and congenital rubella (acquired by the fetus during pregnancy through the mother causing a series of symptoms as permanent damage to the nervous system), among other diseases.

Gestation in the uterus is closely linked to the evolution of these lines. Fingerprints begin to form around the thirteenth week and are already completed by week 18, that is, at the critical moment when the brain starts to develop.

Dermatoglyphics, that is, the science that explains the meaning of the lines on the palm, giving proofs that confirms, for example, the possibility that a child can suffer from diabetes during adolescence. According to James Sinclair, a researcher at the University of Manchester Institute of Science and Technology (UMIST), these lines indicate some facts that have occurred during pregnancy, such as alterations in metabolism, which reveal chromosomal abnormalities and can have consequences on the life of a person. This trend has also verified through different studies that children with an IQ score under 70, which indicates learning difficulties, have a very similar line on their palm.
