Each of us has different fingerprints. The shapes on them are called spiral, loop, arch or double-loop spiral. However, although fingerprints are similar in shape, they are never exactly the same. So how is such a thing possible?
Surprisingly Even the fingerprints of babies who share the same womb are not the same. Apparently things get pretty complicated when it comes to fingerprints.
Without further ado Let’s uncover the curtains of mystery behind fingerprints.
To understand this difference, let’s first look at how fingerprints are formed.
In the early stages of fetal development, the volar pad, that is, the fleshy part under the skin of each finger, stem cell tissue tubers develop. Volar pillow; Large, small, sideways or bumpy growth determines the main shape of the fingerprint.
These shapes are also referred to as arches, spirals, loops or double-loop spirals. Additionally, since the shape and size of your volar pad are partly genetic, you have many relatives and many are identical twins. Each finger has the same main shapes.
However, this does not mean that your fingerprints are the same and DNA It does not alone play a role in the uniqueness of the fingerprint. Because the embryonic skin over the volar pad has several layers of cells that all grow at different rates.
As the inner layer grows, the middle layer bends, causing ridges to form in the upper layer.
The lines called ridges appear primarily on the growing finger. It occurs in parallel with the three areas that exert the most pressure. These three regions; near the nail, near the crease at the first joint, and above the volar pad.
As these lines develop, they sometimes collide with each other and as a result A blockage or split occurs.
Exactly where these ridge lines on the finger meet and what shapes each will take are determined by a number of factors.
These factors include how nerves and capillaries grow in the layer beneath the skin, how fluid pressure changes in the uterus and even the direction in which the finger is directed relative to gravity.
A person prints each fingerprint in a different location. has about 50 different lines And there are more than a quadrillion different possibilities for each fingerprint.
The situation is no different even for babies growing in the same womb. So each of your fingerprints, It is the only one of its kind and is unique.
