Detailed explanation-1: -The thin top layer of the dermis (the inner layer of the skin). The papillary dermis has connective tissue and blood vessels that give nutrients to the epidermis (the outer layer of the skin) and that help control the temperature of the skin.
Detailed explanation-2: -Another feature of some parts of the papillary layer is dermal ridges. These ridges cause ridges in the overlying epidermis, called epidermal ridges. Those ridges and the sweaty marks they leave are what we call fingerprints.
Detailed explanation-3: -Friction ridges or papillary ridges-Elevated strips of skin that begin as raised apertures around the pores and then are joined together into rows forming the ridges. Friction ridges begin to form on the human fetus during the third and fourth months of fetal life.
