A 19-yeаr-оld lifeguаrd hаs spent several summers with frequent, intense sun expоsure and multiple episоdes of blistering sunburn. Using your understanding of normal integumentary structure/function and pathophysiology, answer each part fully. (a) Identify the normal epidermal cell type responsible for UV protection and explain, at the cellular level, how it shields neighboring cells from UV damage. (b) Explain how repeated UV exposure can damage DNA in epidermal cells, and explain why unrepaired DNA damage is physiologically concerning given that these cells divide by mitosis. (c) Predict ONE specific skin function other than UV protection that could be impaired by years of accumulated UV damage. Trace, step by step, how the cellular injury leads to that functional consequence and how it could ultimately affect the whole organism.
