The epidermis contains melanocytes. Which skin layer is primarily responsible for this?

• A. Dermis
• B. Hypodermis
• C. Subcutaneous tissue
• D. Epidermis

Answer: (D)

Melanocytes reside in the epidermis, specifically in the basal layer (stratum basale). They produce melanin and transfer it to neighboring keratinocytes, giving skin its color and providing some protection against UV radiation. The dermis lies beneath the epidermis and is composed mainly of connective tissue, blood vessels, and nerves, while the hypodermis (subcutaneous tissue) is primarily adipose tissue. Since the pigment-producing cells are located in the epidermis, this layer is the one responsible for melanocytes.
