FSC- integumentary system

• What is the role of cholesterol in vitamin D synthesis?


  Cholesterol absorbs UVB and converts it to pre-vitamin D3.
• What happens to pre-vitamin D3 in the skin?


  It is converted to vitamin D3 through thermal isomerisation.
• Where is vitamin D3 further processed after synthesis in the skin?


  In the liver and kidneys.
• What are the protective functions of the skin?

  The skin protects against pathogens, dehydration, and UV radiation.
• What is cutaneous sensation?


  It is the detection of heat, cold, contact, or pain by skin sense organs.
• How do sweat glands contribute to homeostasis?


  They excrete excess water, salts, and small amounts of urea.
• What is vitamin D essential for?


  Calcium absorption and bone health.
• What does UVB stand for?


  A type of ultraviolet radiation from the sun.
• What is a pathogen?


  A microorganism that can cause disease.
• What do exocrine glands do?


  They secrete substances through ducts to surfaces.
• What is the genital tract?


  The system of organs involved in reproduction and urinary waste excretion.
• What does "cutaneous" refer to?


  It relates to or affects the skin.
• What is urea?


  A waste product formed in the liver and excreted in urine and sweat.
• How does the hypothalamus regulate body temperature?


  By increasing metabolic rate and stimulating muscle contraction and shivering.
• What is the function of sweat glands in temperature regulation?


  They cool the body by releasing sweat.
• How do arterioles help in temperature regulation?


  They adjust their diameter to conserve or release heat.
• What do hair erector muscles do for temperature regulation?


  They raise hairs to create an insulating layer of trapped air.
• What is the principle of evaporative cooling?


  Sweat evaporates from the skin, absorbing heat and lowering body temperature.
• How does shivering affect body temperature?


  It increases metabolic activity, generating heat and raising body temperature.
• What is vasoconstriction?


  Constriction of blood vessels in the skin to minimize heat loss.
• What is vasodilation?


  Dilation of blood vessels in the skin to enhance heat dissipation.
• What is insulation?


  A mechanism that reduces heat transfer and helps retain heat.
• What is evaporation in the context of temperature regulation?


  The process by which a liquid absorbs heat and changes into vapor, cooling the surface.
• What is convection?


  The transfer of heat through the movement of fluids or gases.
• What are some causes of atopic eczema?


  Susceptibility to allergies, family history, and environmental triggers.
• How does atopic eczema impact the integumentary system?


  It causes inflammation, redness, and intense itching, disrupting the skin barrier.
• What are the mental health impacts of atopic eczema?


  It can lead to stress, anxiety, and reduced quality of life due to discomfort.
• What is the role of emollients in treating atopic eczema?


  They form a protective barrier to lock in moisture and reduce dryness.
• How do topical corticosteroids help in eczema treatment?


  They reduce inflammation, redness, and itching by suppressing the immune response.
• What dietary changes can help manage atopic eczema?


  Identifying and eliminating food triggers that worsen symptoms.
• How can environmental changes help with atopic eczema?


  Avoiding allergens like pollen and dust reduces exposure to triggers.
• What behavioral changes can help manage atopic eczema?


  Avoiding scratching and irritants can prevent further skin damage.
• What are potential side effects of eczema treatments?


  Allergic reactions, skin thinning, and increased susceptibility to infections.
• What is the chronic nature of atopic eczema?


  It often leads to sleep disturbances and ongoing discomfort.
• How does atopic eczema relate to other body systems?


  It increases the risk of skin infections, allergies, and asthma.
• What is the significance of the skin barrier in atopic eczema?


  A compromised skin barrier leads to dryness, cracking, and increased infection risk.
• What is the relationship between atopic eczema and allergies?


  Atopic eczema can be associated with allergies and may run in families.
• What triggers can exacerbate atopic eczema symptoms?


  Soaps, detergents, stress, and weather changes can trigger symptoms.
