Name and describe the three main types of skin cancer.

Answer (Click to Show Hidden Text)

Skin Cancer is most often caused by overexposure to UV rays
Melanoma - the least common and most deadly/most likely to metastasize. Begins in the melanocytes of the stratum basale of the epidermis, often from a mole since it is already an area of the skin with a high concentration of melanocytes. Diagnosed with ABCDEFG acronym (Asymmetry, Borders, Color, Diameter, Elevated, Firm, Growing).  
Basal cell carcinoma - begins in the cells of the stratum basale of the epidermis, spreads along this layer and then begins spreading towards the surface of the skin, appearing as a raised bump, most common and least aggressive skin cancer.    
Squamous cell carcinoma - begins in the squamous cells of the stratum spinosum and presents as lesions or ulcers, more likely to metastasize than basal cell carcinoma.

Since when :O

Found the EFG in the Openstax Anatomy textbook! I just looked up melanoma on wikipedia, and apparently, the E that stands for evolving applies to all forms of melanoma but the EFG that stands for elevated, firm, growing is for nodular melanoma, the most dangerous form of melanoma (and the ABCDE for other melanomas do not apply)

Yea, I've seen that before

Yeah I saw that too once; I got E on a test and didn't know it sometime last year so I went and looked it all up (back when I actually spent time on Anatomy ).

Since no one has responded, I just wanted to say that you're right!

What is a costamere? What is its role in a muscle cell and how is it important in relation to muscular dystrophies?

What is a costamere? What is its role in a muscle cell and how is it important in relation to muscular dystrophies?

Gratz for stumping me, Wiki'd this (Click to Show Hidden Text)

Thanks for introducing me to Histology: muscle tissue on Wikipedia. And I thought I read every page there was. Costamere connects the sarcomere to the cell membrane, aligned with Z-Disc under the sarcomere. I assume because lack of dystrophin results in muscular dystrophy, the Dystrophin-Glycoprotein Complex in the costamere is disrupted, leading to instability and degeneration.

Just curious, but do you memorize every Wiki page on Anatomy out there?

pigeon no. I just dump it on the cheat sheet. Architectural gear ratio, Stratum malpighii, Virchow's law, and many other obscure crap should not waste brain space.
