Question

Why do individuals who are blind read Braille with the tips of their fingers rather than the backs of their hands?

It would look silly to use the back of the hand

there are more mechanoreceptors on the fingertips than the back of the hand

there are more proprioceptors on our fingers than the back of our hands

it is just convention, either part of the hand would work equally well

Explanation / Answer

there are more mechanoreceptors on the fingertips than the back of the hand.

Mechanoreceptors, which detect mechanical compression or stretching of the receptor or of tissues adjacent to the receptor.Most human mechanoreceptor cells respond to a change in the external stimulus (pressure, temperature, etc) by producing voltage pulses across neurons.Different mechanisms for sensing location, roughness, table edge, table temperature are all mechanoreceptors.
