1. A neighbor is walking her dog to the park during her lunch break on a beautiful sunny day. Explain how her skin is working to protect her from ultraviolet radiation due to intense sun exposure. Be sure to discuss the specific structures and substances involved in this protection.
Given that skin is broken down into three layers, the layer of the skin that would be directly exposed to the ultraviolet radiation from the sun is the epidermis. Her skin has melanin in it which protects it from the ultraviolet radiation.

    Nina Jablonski Speech Summary

    The formation of Melanin in our skin as a response to the exposure to the UV light is the protective mechanism. Melanin, while protecting our skin cells is also responsible for the dark pigment of our skin. It is the same mechanism that is released when we go suntanning. The exposure to the UV light causes the skin to release melatonin, giving us the " "golden glow" many of us are after. People, who live in the northern areas of the globe, further from the Equator where the atmosphere is thicker, shielding from the radiation, do not need as much Melanin in their skin.…

The four different UV wavelengths are classified as UVA, UVB, and UVC. UVA produces the longest wavelength at 320-400nm, UVB produces wavelengths from 290-320nm, and UVC wavelengths are the shortest wavelength that is completely absorbed by the ozone layer. However, it is known that UVA and UVB play an important role in premature skin aging, eye damage and most importantly skin cancers as the UV rays pierce the atmosphere.

The condition is due to the accumulation of disordered elastic tissue in the upper and middle layers of the dermis, which are most susceptible to sun exposure.

    Essay On Tanning

    In Miyamuera’s (et al., 2010) study, the effects of various wavelengths of ultraviolet was compared through repeated exposure of human skin to suberythemal doses of ultraviolet A and/or ultraviolet B for two weeks. The study showed that in the ultraviolet B tanned skin; there was a higher melanin content and ultraviolet-protective effects against DNA damage as there was in the ultraviolet A tanned skin. The tanning from ultraviolet A was caused by the photooxidation of existing melanin and redistribution of pigment granules, thus tanning was seen in both exposures of ultraviolet A and B. However, ultraviolet B increases pigmentation coverage and involves the production of new melanosomes, as it stimulates melanocytes to up-regulate melanin synthesis.…
