How are friction ridges formed
WebThe same theory applies in case of fingerprints. Fingerprints are natural unique patterns formed by friction on epidermal ridges (raised) and furrows (recessed), which appear on the pads of fingers and thumbs. Though these epidermal ridges are found on fingers, palms and soles, they are popularly called just fingerprints.
