Melanocytes are located in the bottom layer of the epidermis called the stratum basale. The overall function of the melanocytes is to produce and distribute melanin, which plays a large role in skin pigmentation.

Then vitamin eventually seeps into the bloodstream and from there ends up in our kidneys and liver. After it passes through the vital organs, it ends up in the bones and that produces bone cells. Vitamin D is the only vitamin known to reproduce by itself while in the body.]]> 2016-09-08 15:06:29 UTC https://padlet.com/diamond5565/vtpwlvtzzs0a/wish/122465991 bmoran618 https://padlet.com/diamond5565/vtpwlvtzzs0a/wish/122466161 Write out the layers of the epidermis from superficial to deep. give a description of each layer. add picture and site source.
1) Stratum Correum- 20-30 dead skins cells. This layer is also called the horny layer.
2) Stratum Lucidum-this is only found in thicker layers of the skin.  For example the foot.
3) Stratum Granulosum- The grainy looking layer of the skin.
4) Stratum Spinosum- This is the most common layer.  Keratinocytes are also located in this layer.
5) Stratum Basale- This layer holds the cells that later become superficial. Melantocytes are also located here

Melanin functions as a boradband ultraviolet absorbent and has antioxidants. Repetitive UV exposure increased pigmentation and skin thickness. Skin cancer is indicating that highly pigmented skin is profoundly protected from carcinogensis. Given that UVA damage is largely thought to occur via oxidative mechanism this may account got a positive role for UVA in melanoma induction.

Melanin function differs between people close to and far from the equator by protecting the skin from the UV rays in those who live closer to the equator, and by absorbing the vitamin D from the sun's rays in those who live near the poles, farther away from the equator.

Melanin builds up as protection against the sun when it senses it. The sun provides vitamin D so if the body lacks sun, it lacks vitamin D, which means that a larger amount of melanin is not needed at the moment. I can personally attest to this being true because my skin tone changes based on the amount of sun I receive from time to time. My skin is usually lighter in the winter because less sun is peeking through.]]> 2016-09-09 02:49:41 UTC https://padlet.com/diamond5565/vtpwlvtzzs0a/wish/122635410 diamond5565 https://padlet.com/diamond5565/vtpwlvtzzs0a/wish/122750188 Question 1- Brenna
