Chapter 15, Problem 2TMW
Some strains of Staphylococcus aureus produce exfoliative toxin, a chemical that causes portions of the entire outer layer of the skin to be sloughed off in a disease called scalded skin syndrome. Given that cells of the outer layer are going to fall off anyway, why is this disease dangerous?

Gyutaro decided to have tattoos. Before this, he assured his mentor, Urokodaki, that the tattoos will eventually disappear. He said that skin cells shed at every four weeks. Do you support the reasoning of Gyutaro regarding this matter? Why or why not?
What is the shape of a skin cell that helps it create a protective layer.
A. The cell is tapered at each end and allows them to fit together easily.
B. The cell is long and rectangular so that they stack and make straight pathways into the body.
C. The cells are short and flat which make they easy to layer and overlap.
D. The cells have no defined shape so that they move easily with the body

- Which of the cytoskeletal structures depicted provide resistance against mechanical stress (think about the disease that causes blistering of the skin with the slightest touch)?arrow_forwardUltraviolet (UV) radiation is known to damage skin; excessive exposure can cause enough damage to stimulate acute inflammation (sunburn). Histologic examination of the epidermis shows a layer of keratinocytes that have committed premature apoptosis (killed themselves before they normally would have died) and a lack of Langerhans cells in the affected region. Severe sunburns are followed several days later with non-bleeding blistering and peeling of large patches of skin. In the following weeks, the epidermis becomes thicker and darker (tan!). Hypothesize about which layers and/or sublayers of the skin are primarily affected; and about why the blistering, peeling, thickening, and darkening occurs. Be sure to explain your reasoning. This answer requires a logical hypothesis based on what we’ve learned about the specific microanatomy of the skin; it does not require “THE” correct answer.arrow_forwardan average skin (epidermal) cell has a diameter of 30 micrometers. The majority of the surface of the human body is covered by skin cells. The average surface area of an adult male is 1.9 m2 and an adult female is 1.6 m2. Use the information above to calculate the approximate number of skin cells needed to cover the surface of your body (you can assume that you are an average human). Use this formula to determine the area an average skin cell covers: Area = π (radius)2 Plug the radius (1/2 the diameter) of an average skin cell into the equation. area of an average skin cell ____________________ Next, convert your surface area (average male or female) from m2 into mm2 your surface area____________________ Then, divide your surface area by the average area of a skin cell. number of skin cells covering your body ____________________arrow_forward
