Question

Protection from ultraviolet rays is provided by

• A. Stratum corneum layer
• B. Stratum granulosum layer
• C. Stratum lucidum layer
• D. Melanocytes

Answer 1

Answer: (D)

Melanocytes

Human skin is repeatedly exposed to the ultraviolet radiation that influences the function and survival of many cell types and is regarded as the main causative factor in the induction of skin cancer. Skin pigmentation is considered to be the most important photoreceptive factor as melanin functions not only as a broadband UV absorbent but also has antioxidant and radical scavenging properties.
Thus, the correct answer is option D.
