They are found only in the tongue, lips, palms, fingertips, nipples, and the clitoris and the crests of the ridged band at the tip of the male foreskin. These remarkable cells process tens of thousands of information impulses per second and can sense texture, stretch, and vibration/movement at the micrometre level. These are the cells that allow blind people to “see” Braille with their fingertips. Cut them off and, male or female, it’s like trying to read Braille with your elbow. <br />Anonymousnoreply@blogger.com
