What are the Main Components of the Papillary Dermis?
The papillary dermis consists of several key components: - Collagen fibers: These provide structural support. - Elastin fibers: These confer elasticity. - Ground substance: A gel-like material that fills the space between fibers and cells. - Blood vessels: These form a network of capillaries that supply the overlying epidermis. - Nerve endings: These are involved in the sensation of touch and temperature. - Fibroblasts: Cells responsible for the production of collagen and elastin. - Immune cells: Including macrophages and mast cells, which play roles in immune responses.
