Which layer of skin contains melanocytes?

The epidermis is the correct answer as it is the outermost layer of the skin where melanocytes are located. These specialized cells are responsible for producing melanin, the pigment that gives skin its color and provides some protection against ultraviolet (UV) radiation. Melanocytes are primarily situated in the basal layer of the epidermis, which is the deepest part of this skin layer, but they play a crucial role throughout the epidermis.

In contrast, the dermis lies beneath the epidermis and contains structures like hair follicles, glands, and connective tissue, but it does not house melanocytes. The hypodermis, or subcutaneous layer, is deeper than the dermis and primarily consists of fat and connective tissue; it also lacks melanocytes. Therefore, recognizing the role of melanocytes and their specific location in the epidermis is vital for understanding skin anatomy and functioning.
