why do we have lines on our hands
Stop whatever youвre doing right now and stick the palms of both your hands in front of your face. What do you see? A bunch of lines crisscrossing all across your palms, right? Have you ever wondered why they re there, since they donвt seem to serve any purpose (or so it seems)? Why do we have so many lines on our palms? Short answer: The lines on our palms are known as palmar flexion creases, and theyвre there to help us fold, stretch, squeeze, scrunch and do other such things without excessively stretching or squeezingВthe skin on the hands. The lines on our palms are scientifically known as palmar flexion creases. These creases begin to form around the 12th week of gestation, i. e. , when the baby is still in the womb. What this means is that we are all born with these lines on our palms. Their primary function is to help squeeze and stretch the skin of the palm. Itвs only along these lines that the handвs skin folds or bunches up in accordance with the relevant position of the hand (e. g. , curling, stretching, making a fist etc. ). Apart from offering this physical advantage, palmar flexion creases can also help identify certain medical disorders in an individual.
Hands are indisputably one of the the hardest working organs (amongst the external ones) of the body. Think of the plethora of physical activities you do with them day in and day out. You constantly pick things up, pull/push, squeeze, turn and twist stuff using your hands. It s actually quite pointless to list all the activities we do using your hands because there are just so many! In order for your hands to do all these physical activities, the skin that covers them must be able to adjust suitably to complex positions. Therefore, when you stretch, fold, bend or make a fist using your palms, the skin mustВbe able to follow suit. If not for the lines on our palms, bags of loose skin would beВhanging out from under our palms and fingers. Not only would that beВa terrible waste of skin tissue, but also a ratherВunpleasant sight to behold. Can reading palm lines (palmistry) foretell the future? A sizable portion of the general public actuallyВbelieves that the lines on our palms can help foretell our future.
Fortune tellers all over the world make a living out of reading peopleвs palms and predicting their future! However, as of now, palmistry is considered a superstitious or
В due to a serious lack of empirical support behind palmistry predictions, as well as different (and sometimes even contradicting) interpretations of the same set of lines on an individualвs palms across different cultures. In other words, if youвre someone who believes in an idea or a theory only if thereвs sufficient scientific research and proof backing it, then going to a fortune teller to help predict the outcome of an exam, a business deal, or any other (future) event of your life is certainly not an option for you, at least until the powers that be accept palmistry as a вregularв science. Palmistry Single Transverse Palmar Crease Some people think the palm lines in human hands foretell the future through the practice of palmistry. Scientifically speaking, however, the lines on a palm, or palmar flexion creases, help the hand s skin stretch and squeeze.
They can also help identify certain medical conditions. in the womb at around the 12th week of gestation, and are present on a baby s hand when he or she is born. When you clench your hand, palm lines provide an avenue for the hand s skin to fold without bunching up and making it difficult to grab onto items. That may also be why there are strong creases where the bones in the fingers and thumb meet. Most people have three prominent creases across the surface of their palms, but sometimes there is only one crease, according to the National Institutes of Health. Having only a single palmar crease (once known as a simian crease ) might indicate abnormal development. It s sometimes present in babies with conditions such as Down syndrome or.
