Verified step by step guidance

Understand the structure of the skin: The skin is composed of three main layers—epidermis, dermis, and hypodermis. The dermis itself is divided into two layers: the papillary layer and the reticular layer.

Focus on the dermis: The dermis is the middle layer of the skin and contains various structures such as blood vessels, nerve endings, and connective tissue. It plays a key role in sensation and support.

Learn the function of the papillary layer: The papillary layer is the upper portion of the dermis, located directly beneath the epidermis. It contains capillaries, lymphatic vessels, and nerve endings that are sensitive to touch and pressure.

Compare the reticular layer: The reticular layer is the deeper portion of the dermis. It is primarily composed of dense connective tissue and provides structural support but is less involved in sensory functions compared to the papillary layer.

Eliminate incorrect options: The hypodermis is not part of the dermis; it is a deeper layer composed of fat and connective tissue. The stratum corneum is part of the epidermis, not the dermis. Based on the sensory function, the papillary layer is the correct answer.
