Which layer of the dermis contains small cone-shaped projections of elastic tissue that points upward into the epidermis?

The papillary layer is the uppermost layer of the dermis and is characterized by its small, cone-shaped projections known as dermal papillae. These projections extend upward into the epidermis, enhancing the surface area between the two layers. This increased surface area aids in the exchange of nutrients, oxygen, and waste products, and it also plays a crucial role in the formation of fingerprints. The papillary layer is rich in capillaries, nerve endings, and collagen and elastic fibers, contributing to the skin's overall texture and elasticity.

In contrast, the reticular layer is located beneath the papillary layer and is denser and thicker, primarily containing collagen fibers that provide strength and resilience. The stratum basale and stratum spinosum are both layers of the epidermis, not the dermis, and primarily involve cell division and support in the skin's outermost protective layer.
