Which type of cells in the epidermis produce melanin?

• A. Keratinocytes
• B. Fibroblasts
• C. Melanocytes
• D. Adipocytes

Answer: (C)

The cells in the epidermis that produce melanin are melanocytes. These specialized cells are primarily located in the basal layer of the epidermis, where they synthesize the pigment melanin, which gives color to the skin, hair, and eyes. Melanin plays a crucial role in protecting the skin from ultraviolet (UV) radiation by absorbing harmful rays and reducing the risk of DNA damage that can lead to skin cancer. In contrast, keratinocytes are another type of epidermal cell responsible for producing keratin, a protein that helps form the skin's protective barrier. Fibroblasts are found in the dermis layer of the skin and are involved in producing connective tissue and collagen, which provide structural support. Adipocytes, or fat cells, are not part of the epidermis; they are located in the subcutaneous layer and are responsible for storing energy and insulating the body. Understanding the specific functions of these cell types highlights the unique role of melanocytes in the production of melanin and their importance in the protective mechanisms of the skin.
