What is the name of the upper layer of the dermis that connects to the epidermis?

The papillary layer is the uppermost layer of the dermis that specifically connects to the epidermis. This layer is comprised of loose connective tissue and contains many fine collagen and elastin fibers, which provide the skin with flexibility and strength. The papillary layer contains dermal papillae, small, nipple-like projections that interlock with the epidermis. This structure enhances the exchange of oxygen, nutrients, and other substances between the two layers. Additionally, these projections form the basis for fingerprints.

In contrast, the reticular layer is the deeper layer of the dermis, providing strength and elasticity but does not directly connect to the epidermis. The subcutaneous layer, also known as the hypodermis, lies beneath the dermis and serves to insulate and protect the body, while the epidermal layer is a term that refers to the outer layer of skin itself, which does not connect with the dermis in the context of upper layers. The choice that correctly identifies the layer connecting to the epidermis is the papillary layer.
