Final answer:
Dermal papillae in the skin contain capillaries, sensory touch receptors, and create epidermal ridges known as fingerprints.
Step-by-step explanation:
The dermal papillae in the skin contain capillaries and sensory touch receptors. They are fingerlike projections that extend upward from the papillary layer of the dermis into the epidermis. The main function of dermal papillae is to increase the surface contact between the epidermis and dermis, strengthening the connection between the two layers of skin. Additionally, dermal papillae in the palms and soles create epidermal ridges, which form unique patterns commonly known as fingerprints.
