Caption: Ridges on palm of hand. Close-up of the lines and whorls of patterning on the palm of a human hand. These are unique to individuals, and can be used as a means of identification. In addition to this, the epidermal ridges amplify vibrations when touching a surface, amplifying the signal to the sensory nerves in the skin.
