Explanation:
Detailed explanation-1: -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).
