What is the sense of a fingerprint?

A fingerprint is an impression of the friction ridges on all parts of the finger. A friction ridge is a raised portion of the epidermis on the palmer (palm) or digits i.e. fingers and toes or plantar or sole skin, consisting of one or more connected ridge units of friction ridge skin. This is also known as Epidermal Ridges which is originated by the underlying interface between the dermal papillae of the dermis and the interpapillary (rete) pegs of the epidermis.
