PATHOLOGY

Detailed explanation-1: -The papillary dermis, the uppermost layer, connects with the epidermis and comprises various fine and loosely arranged collagen fiber. Within this area, there are dermal papillae extensions that act as junctions (DEJ) into the epidermis.

Detailed explanation-2: -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-3: -Papillary dermis: The papillary layer is the top layer of your dermis. It’s much thinner than the reticular dermis. It consists of collagen fibers, fibroblast cells, fat cells, blood vessels (capillary loops), nerve fibers, touch receptors (Meissner corpuscles) and cells that fight bacteria (phagocytes).
