What dermal tissue structure are responsible for fingerprints?

Answer 1

The dermal papillae are small, nipple-like protrusions of the dermis that reach into the epidermis, bringing food and oxygen to the lower layers of epidermal cells. In addition, a papilla nourishes every hair follicle. Rows of papillae protruding from the dermis into the epidermis form ridges that create patterns on the skin of the hands, feet, and body. These papillary ridges on the fingertips are responsible for fingerprints. These ridges develop sometime before birth. Not only is the pattern unique for each individual, but also it never changes except to grow larger.

Answer 2

The dermal papillae are responsible for forming fingerprints. These are found in the upper layer of the dermis and create raised patterns on the skin's surface, resulting in unique fingerprint patterns for each person.

Answer 3

The dermal tissue structures responsible for fingerprints are dermal papillae. They are tiny extensions of the dermis into the epidermis.
