Step by step
Solved in 4 steps
- When you are outside on a cold day, your skin is much paler than normal. Later, when you enter a warm room, your face becomes flushed. What are the reasons for the change in color of your face?The skin can be a reflection of a person's health. For example, people who have issues with their liver can have a buildup of a toxic substance called bilirubin, which is a byproduct of red blood cell breakdown. This can cause a person's skin to have a yellowish tint. What is this condition called?Explain the differences between inner and outer hair cells.
- Researchers studying skin color consistently measure skin color from exactly where on the body?Chronic alcoholism damages the liver. In people whohave alcohol-induced liver damage, the blood concentration of albumin can be unusually low. Explain why a low concentration of blood albumin can cause edema, a condition in which excess fluid accumulates in body tissuesExplain the cellular and molecular mechanisms that determine the color of human skin.
- The pigment epithelial cells may undergo apoptosis in response to the oxidative stress of free radicals(chapters 3 and 19). Explain what functions could be disturbed by a damaged pigment epithelium, and relate this to the disease of macular degeneration.How do melanocytes and keratinocytes work together to protect the skin from UV damage? a. Keratinocytes maintain the proper pH for melanocytes to synthesize melanin granules. b. Keratinocytes provide the melanocyte with nutrients critical for melanin synthesis. c. Keratinocytes maintain the appropriate temperature so the melanin will not denature. d. Keratinocytes accumulate melanin granules to shield the keratinocyte’s DNA.Explain the role of keratin in the skin.
