What is "papillary dermis"?
The papillary dermis is the uppermost layer of the dermis, situated beneath the epidermis, and is characterized by its unique papillary projections. It provides structural support, nourishment, and oxygenation to the overlying epidermis through its rich blood supply. Additionally, it plays a crucial role in temperature regulation and the sensation of touch by housing various nerve endings and receptors.
