    Study Notes

    Dermis

    • The papillary layer of the dermis is responsible for discriminative touch
    • The reticular layer of the dermis is composed of dense irregular connective tissue

    Dermis Sensory Receptors

    • Free nerve endings detect pain, temperature, and itching in the dermis

    Epidermis-Dermis Interface

    • Epidermal pegs/ridges in the dermis increase surface area for strong anchor points between the epidermis and dermis

    Hypodermis

    • The main function of the hypodermis is to attach the skin to underlying tissues and organs
    • Pacinian corpuscles, a type of sensory receptor, respond to vibration in the hypodermis
