It has long been known that the thickness of the epidermis varies around the body. For example, skin is thicker on the soles but thinner on the ears. However, the mechanism for maintaining the relative thickness of the outer skin, or epidermis, has been largely unknown.

Now, the research group, led by Professor Tomomi Nemoto of the university's Research Institute for Electronic Science, has established a new method for three-dimensional, real-time observation of the deep structure of the skin in living mice using advanced microscopy technology.
...
The team's analysis revealed for the first time that in thicker skin, basal cells divide obliquely with high frequency, whereas for basal cells in thin skin -- such as the back and ears -- divisions in the basement membrane were mostly parallel. By analyzing divisional direction three-dimensionally, correlations were found between the thickness of the epidermis and the frequency of oblique division with regard to the basement membrane.

In case you always wondered.

    I can't be the only one who enjoys walking, running, and jogging - using my ears instead of my feet. This mystery of why skin is thicker on certain body parts must be solved!

    Can they explain why The Donald is so thin skinned? Maybe we should ask Hillary, she seems to know how to get under it easily.

    I only jog using my crotch, you insensitive clod!
