Which layer of the skin is known for containing melanocytes?

• A. Stratum corneum
• B. Basal layer or stratum germanitivum
• C. Stratum granulosum
• D. Reticular layer

Answer: (B)

The basal layer, also known as the stratum germinativum, is the deepest layer of the epidermis and is primarily responsible for the production of new skin cells. It is here that melanocytes, the cells responsible for producing melanin (the pigment that gives skin its color), are located. Melanocytes play a crucial role in protecting the skin from ultraviolet (UV) radiation by absorbing and dispersing the UV rays, which can lead to skin damage and increased risk of skin cancer. In this layer, the melanocytes interact with the keratinocytes (the predominant cells in the skin) to provide pigmentation. This relationship is essential as it helps in determining an individual's skin tone and provides a barrier against UV damage. The presence and activity of melanocytes in the basal layer is central to both the cosmetic appearance and the health of the skin.
