    Study Notes

    Epidermis

    • Langerhans cells act as macrophage-like dendritic cells
    • Merkel cells are associated with sensory nerve endings and found in the stratum basale
    • Stratum corneum is known as the "horny layer"
    • Melanocytes are responsible for producing the pigment melanin

    Dermis

    • The papillary layer contains dermal papillae
