eady to be installed, but first we need to close some apps. Update now This case study relates melanin to skin health. (10 pts) You are a clinician living in Alaska with 2 patients to treat. Patient 1: Mr. Tutio recently moved to Alaska from Ethiopia, in equatorial Africa. He has highly melanin pigmented black skin and dark eyes and hair inherited from his African ancestors. Patient 2: Ms. Eogner is Finnish, her ancestry is Northern European. She is blonde, blue eyed and has lightly melanin pigmented pale skin. Ms. Eogner informs you that next month she will be moving to Ethiopia In paragraph form explain to me IN YOUR OWN WORDS the advice you would give each patient. This advice should address how their skin pigmentation and changes in UV light exposure might affect their health as each has moved (or will move) to a new place on the globe. Be sure to fully EXPLAIN WHY (using the appropriate anatomical and physiological terminology) you have chosen this particular clinical advice for each patient

Explanation / Answer

As with peoples having migrated northward, those with light skin migrating toward the equator acclimatize to the much stronger solar radiation. Most people's skin darkens when exposed to UV light, giving them more protection when it is needed. This is the physiological purpose of sun tanning. Dark-skinned people, who produce more skin-protecting eumelanin, have a greater protection against sunburn and the development of melanoma, a potentially deadly form of skin cancer, as well as other health problems related to exposure to strong solar radiation, including the photodegradation of certain vitamins such as riboflavins, carotenoids, tocopherol, and folate
