The type of skin cancer that is considered the most dangerous: a. Often arises from a pre-existing mole. b. Arises from keratinocytes of the stratum spinosum. c. Is the most common type of skin cancer. d. Affects the Merkel cells that function in sensory reception. e. The rule of 9's is used to diagnose this condition. Match the following cell types with their function: Keratinocytes Melanocytes Langerhans Merkel A. Physical Protection B. Immune system C. Sensation D. Protection from UV radiation The ventral abdomen skin was cut and bleeding occurred. Which of the following could NOT have been damaged? a. Stratum lucidum b. Papillary dermis c. Stratum corneum d. Stratum spinosum e. Stratum germinativum Albinism is a genetic disorder in which, although melanocytes are present in normal numbers in the skin, melanin is either not made at all or in greatly reduced numbers. If someone has albinism, which of the following treatments would be the best to advocate for optimum health? a. Avoid piercing or cutting your skin due to excessive bleeding that could result. b. Stay out of all sun to avoid skin cancer and also take a Vitamin D supplement as a result of the lack of sun exposure. c. Take a vitamin D supplement, but as long as you do that, exposure to the sun should not be a factor. d. Be careful around fire and hot objects due to the lack of sensation of the skin. e. Stay out of all sun to avoid skin cancer. There have been many investigative TV shows and magazine articles that have examined the number of bacteria in different areas, and it is quite scary that everything we touch is teeming with bacterial cells. What do we have to help us deal with the bacteria on our skin? a. Skin secretions have a low pH, which retards the multiplication of bacteria. b. Skin uses vasoconstriction and vasodilation to control blood flow to the periphery and to kill bacteria by cutting off the blood supply. c. Antibodies secreted onto the skin's surface are aimed to kill any particular type of foreign invader. d. Skin secretions have a high pH, which retards the multiplication of bacteria. e. Skin is immune to the effects of bacteria and only will allow the multiplication of viruses. The epidermis consists of several layers of ___________ tissue, and the dermis consists of ___________ tissue. a. Epithelial. Dense Regular Connective Tissue b. Vascular. Avascular c. Non-keratinized. Keratinized d. Connective. Epithelial e. Epithelial. Connective The drug colchicine is anti-mitotic, which means it prevents cell division.

Cells of the stratum corneum
