    papillary layer
  10. vascular region
    dermis (as a whole)
  11. actively mitotic (dividing) epidermal region, deepest epidermal layer
    stratum basale
  12. cells are flat, dead "bags" of keratin
    stratum corneum (horny layer)
  13. site of elastic and collagen fibers
    dermis (as a whole)
  14. general site of melanin formation
    stratum spinosum (prickly layer)
  15. major skin area where derivatives (hair, nails) reside
    epidermis (as a whole)
  16. largely adipose tissue, anchors skin to underlying tissues
    hypodermis
  17. also known as stratum germinativum
    stratum basale
  18. layer where melanocytes are found
    stratum basale
  19. cell in this layer contains keratinohyalin and lamellated granules
    stratum granulosum
  20. accounts for the bulk of epidermal thickness
    stratum corneum
  21. provides mechanical strength to skin
    dermis (as a whole)
  22. responsible for skin color of dark skin
    melanin
  23. gives an orange cast to skin
    carotene
  24. protects cells from sun damage
    melanin
  25. give pink tint to light skinned persons
    hemoglobin
  26. phagocytized by keratinocytes
    melanin
  27. found in stratum corneum
    melanin
  28. bluish cast of skin; resulting from lack of oxygen
    cyanosis
  29. could be caused by anemia or low blood pressure
    pallor
  30. may indicate liver disease
    jaundice
  31. clotted mass of blood under the skin
    hematoma
  32. result of inflammation, allergy, and fever
    erythema
  33. HOW langerhan's cells and macrophages --> helps to protect the body
    biological; part of immune system
  34. HOW bactericidal secretions-- help protect the body
    kills bacteria
  35. HOW keratin--
    waterproofing
  36. HOW melanin--
    protects skin from UV light
  37. HOW acid mantle--
    decreases bacterial growth
  38. the role of sweat glands in maintaining body temp: & how regulated
    as sweat evaporates, body is cooled; regulated by autonomic nervous system
  39. two major concerns in burn patients? -- how can it lead to death
    • major fluid loss leads to dehydration &
    • electrolyte imbalance leads to renal shutdown then shock then death
    • -- infection where the skin barrier is lost
  40. full thickness of skin is burned; skin can be gray white, cherry red or charred
    3rd degree burn
  41. blisters
    2nd degree burn

  43. epidermal and some dermal damage
    2nd degree burn
  44. regeneration impossible; requires some type of skin graft procedure
    3rd degree burn
  45. pain is absent because nerve endings in area are destroyed
    3rd degree burn
  46. rule of nines.... how is it used when treating burn victims?
    divides body into 11 areas, each worth 9%... method of estimating fluid loss
  47. CNCR: cells of stratum spinosum develop lesions; metastasizes to lymph nodes
    squamous
  48. CNCR: cells of lowest level invade dermis and hypodermis; slow to metastasize
    basal
  49. cancer of pigment producing cell; most deadly 
    melanoma
