Why do we feel more details when we touch something with the tips of our finger, than the rest of our body?

Why do we feel more details when we touch something with the tips of our finger, than the rest of our body?

Is this because we have different kind of nerves (sensors) on the tips of our fingers than the rest of our body? Or is it our brain thats somehow causing this to happen?

Your fingers are made to touch! It's useful to be able to get very detailed tactile sensations. Your fingertips have a higher concentration of mechanoreceptors. A popular high school experiment is to place a blindfold on someone and pick a part of their body with two pencils varying distances apart. You'll find that you can distinguish there are two separate points of contact if you do it on your hand, while your back will require them to be much father apart before you can sense two points of contact!
