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.
