    20 Square Feet
  16. Keratinization
    The process by which cells form fibrils of keratin and harden

  19. Intradermal Injections
    Injected within the skin
  20. Intramuscular Injections
    Administered into muscles
  21. Hypodermic Injections
    • 1. Subcutaneous injections
    • 2. Intramuscular injections
  22. Transdermal Patch
    Drum diffuses into the epidermis and enters the blood vessels of the dermis
  23. Transdermal Patch Uses
    • Protect against:
    • 1. Motion sickness
    • 2. Chest pain associated w/ heart disease
    • 3. Elevated blood pressure

    4. Delivers nicotine to help people stop smoking
  24. What layer of the epidermis is found only in the thickened skin of the palms and soles?
    Stratum lucidum
  25. What layer of the epidermis may be missing where the epidermis is thin?
    Straum granulosum
  26. Epidermis Protects Against:
    • 1. Excessive water loss
    • 2. Mechanical injury
    • 3. Effects of chemicals
    • 4. Disease-causing microorganisms
  27. Melanocytes
    Specialized cells in the epidermis that produce melanin
  28. Melanin
    Dark pigment normally found in skin and hair that gives it its color
  29. Melanin Protects Against:
    Mutations of the DNA of skin cells and other mutations caused by ultraviolet radiation
  30. Cytocrine Secretion
    Long extensions of melanocytes transfer melanin granules into other nearby cells
  31. What is skin color largely determined by?
    Amount of melanin produced by melanocytes and the and distribution and size of the pigment granules
  32. Environmental Factors Influencing Skin Color
    • 1. Sunglight
    • 2. Ultraviolet light from sun lamps
    • 3. X-rays
  33. Physiological Factors Influencing Skin Color

    • 3. Chemicals
  34. What causes fingerprints?
    Dermal papillae
  35. Pressure Ulcer AKA
    • 1. Decubitus ulcer
    • 2. Bedsore
  36. Pressure Ulcer
    Weight of body presses against a surface and blocks the skin's blood supply, tissue begin to break down
  37. Dermal Blood Vessel Functions
    • 1. Supply nutrients to all skin cells
    • 2. Help regulate body temperature
  38. Hair Follicle
    Tubelike depression in the skin in which a hair develops
  39. Arrector Pili Muscle
    Attatches to each hair follicle, causes the hair to stand on end when it contracts
  40. Sebaceous Glands
    Holocrine glands that secrete an oily mixture into the hair follicles that keeps the hair and skin soft, pliable, and waterproof

  45. Apocrine Glands
    Become active wen a person is upset, frightened, or in pain; common in axillary regions and groin
  46. Hypothalamus
    Signals dermal blood vessels to dilate when the body is hot and some of the heat is carried to the outside
  47. Nervous System
    Stimulates the eccrine sweat glands to become active when the body is hot
  48. Inflammation
    A tissue response to stress that causes blood vessel dilation and fluid accumulation in the affected region
  49. Cutaneous Carcinomas
    Most common type of skin cancer occurring frequently in light-skinned people over age 40; caused by regular exposure to sunlight
  50. Cutaneous Melanomas
    May appear in people of any age and are cause by short, intermittent exposure to high-intensity sunlight

    Bacterial infection of the skin, produced when bacteria enter a hair follicle
  56. Carbuncle
    Bacterial infection, similar to a boil, that spreads into the subcutaneous tissues
  57. Cyst
    Liquid-filled sac or capsule
  58. Dermatitis
    Inflammation of the skin
  59. Eczema
    Noncontagious skin rash that produces intching, blistering, and scaling
