what is the purpose of finger prints in hand?

Answer 1

There is no purpose of them being individual.

They are just there to give grip when we are handling objects.

Answer 2

They probably aid in grip but you can probably answer the question yourself if you look at the differences between your finger tips and the rest of the skin on your fingers.

The skin leading upto the tips has grooves all leading one way, this probaby helps with grip to but if you try and move it about it doesn't stretch much in the direction of the grooves. If you run a nail against the skin to the tip then you'll probably notice the difference in feeling as it reaches the tip. The tip is pack with sensitive nerve endings that are used to determine the feel of something, without the whorl design the nerves could probably not be arranged in such a way as to effectively feel these minor differences in texture.

The quick answer is - the purpose of finger prints is to pack the many thousands of nerve endings together in an effective manor to feel minute differences in texture.

With toes the same applys. Your toes are sensitive to minor differences in texture in the same way. However, this is also true for the entire sole of the foot, the effect is amplified by socks and shoes constantly covering the sole, keeping it super-sensitive.

Answer 3

There is no real purpose to them - the fact that everyone has a different finger print is a chance of biology. Your finger print depends on conditions in the womb as you were developing.

The ridges ans whorls on your fingers probably do help with grip, and may help to feel the texture of an object.

Answer 4

Of course the question has a second part. If we have the fine ridges and whorls on our fingers for grip, then why do we have them on our toes and soles of our feet? Has nature designed us to have prehensile toes? Why did our toes maintained their fine prehensile ridges long after they lost their practice use?

If a person burns his hands and gets a skin graft from another part of the body, then he wouldn't have prints. Would he also not be able to grip anything?

Therefore, I conclude that the finger prints are NOT for grip. They must be for another purpose.. For instance.. added flexibility of the skin.

Answer 5

That's an excellent question! Finger (and toe) prints serve many functions:

-The most commonly-stated, as seen above, is to provide better grip. In fingers, when we hold things, and in toes, when we walk.

-Finger and toe prints also channel moisture in our hands and feet, so that they are not constantly slippery with sweat (although it seems like in certain people, this has limited success!). :)

-Especially in feet, toeprints can help to prevent blisters by providing a small extra cushion between the toes, thus reducing the pressure and fluid build up between them.
