Answer:
The dermis lies below the epidermis and contains collagen, elastin and glycosaminoglycans. Collagen gives structure to the skin, elastin gives elasticity and glycosaminoglycans form the connective tissue. Three types of cells are present, the fibroblasts, which produce collagen, macrophages, which play a role in the skin's immune reponse, and adipocytes, or fat cells. The dermis itself is composed of two layers, the papillary and reticular dermis. The upper papillary layer contains papillae which end in capillaries or Meissner's corpuscles. The reticular dermis contains the bundles of collagen.
