General DB Instructions

 

 1. Before you answer this discussion board, please read the flashcards on Skin.

 

 2. Your grandmother shows you a mole on her arm. How could you visually tell if the mole was cancerous? 

 

3. How would you explain to her that the mole may be cancerous. 

 

4. What are the pros and cons of disclosing that information? 

 

5. Read an article online about any topic covered this week and cite it as a reference below your post using proper format as described in the instruction link below.

1) You have until Wednesday to make your initial post.

2) The original post must be 150+ words and have a reference in APA format but the replies do not need a reference. Read an article on the topics of the week, and use one as a reference for the original post to share with your classmates as an idea for outside reading.

3)   Read the posts of your classmates and reply to two or more of their posts before Sunday at 11:59 pm.

4) The replies should start with a greeting and then expand the discussion

5) All your posts must be your reflection of the topic in your own words.

6) Write the phrase “Word Count” and the number at the end of each post. Each of the 3 posts must be 150+ words, but any additional replies may be shorter.

7) Do not put any attachments on DB posts. No one wants to download something to read it.

8) Type your posts into a Word doc to save on your computer in case your submission does not go through properly. Then copy and paste it into the Discussion Board window and hit the "Submit" button.

? Keratin is a waxy protein substance only found in the epidermis. It makes up the nails, hair, and is also in each superficial skin cell.

? It can absorb water like a chamois cloth that is used to dry your car, so keratin swells when soaking wet. It makes the skin look wrinkled on your fingers and toes when you are in the tub too long.

? The water evaporates when you dry off, and because of water’s cohesive abilities, it sticks to itself and pulls more water out of your body, so soaking in the tub will dry your skin out...unless you put lotion on right away to block evaporation and keep the water in the epidermal layers. Lotions will not penetrate to the epidermis or dermis, just water.19

? The secret ingredient of all moisturizers is WATER. They work superficially on the epidermis. Although keratin is waterproof, it swells when wet.

? So, if you put a moisturizer on skin, stratum corneum expands, and hides wrinkles.

? You get the same effect by soaking in the tub and putting on any lotion, and that’s cheaper than expensive creams.

 

  ? Why do black-skinned people have lighter colored palms and soles?

? Only the Stratum Basale has pigment-containing cells, but the stratum lucidum contributes the color of protein, which is an orange- tan color.

? In the palms and soles, the stratum lucidum is present. The tan colored protein blocks the underlying melanocytes from view.
