The surface area of contact between the epidermis and the dermis is increased by structures called __________. This increased surface area allows for improved gas and nutrient exchange and waste removal by dermal blood vessels.

It is a part of the epidermis and is its innermost layer.
It is located at the junction of the inner dermal and outer epidermal layer.
It remains attached to the basement membrane underneath by structures called hemidesmosomes.
It forms finger-like projections into the underlying dermis, that increases its surface area which allow efficient exchange of nutrient and waste products.
Touch-sensitive Merkel cells and melanin-producing melanocytes are interspersed in this layer.

The surface area of contact between the dermis and the epidermis is enhanced by the compositions called dermal papillae.

What are dermal papillae?

It is a finger-like fold or projection found in the superficial part of the dermis. It enhances the strength of the association between the dermis and the epidermis, that is, the greater the folding, the stronger is the connections created.

The dermis elongates up into the epidermis into the compositions known as dermal papillae. They exhibit two activities:

They help in adhesion between the epidermal and the dermal layers.
In the regions of thick skin like this they offer a large surface region to nourish the epidermal layer.

Thus, the correct answer is dermal papillae.
