- Determination of touch receptor density.
The values give the distribution of the Meissners Corpuscles, which are involved in fine touch and important for our appreciation of texture. Shorter the distance means higher density of Meissners Corpuscles in that area, e.g. it gives more precise detection.
The differences are related to the usage of the areas.
Fingertips have the shortest distance as we always use our hand to detect or hold something. Precise detection ensure us can escape from danger instantly. Dorsal surface of lower arm and Shoulder are less sensitive as they are not use to touch things or for detection.
However, this testing method is not very accurate, as there are other touch receptors, e.g. Merkels Disks, which are also sensitive to light touch. Also, the daily habits may change the density of the receptors.
