    amputation
  3. consisting of the malleus, incus, and stapes; these bones transmit sound waves to the inner ear
    auditory ossicles
  4. tearing away of
  5. a body part or structure; the part is ofen still attached to the body by a small flap of skin
    avulsion
  6. material used to secure a dressing in place and provide pressure over the dressing to aid in control of bleeding
    bandage
  7. injusry resulting from the severe compressing force that damages and somtimes tears soft tissues and underlaying structures
    crush injury
  8. skin layer below the epidermis composed of dense connective tissue that contains the nerves, blood vessels, sweat and sebaceous glands, and hair follicles
    dermis
  9. any material that covers a wound, prevents introduction of further contamination into the wound, and aids in bleeding cntrol
    dressing
  10. balck and blue marks caused by bleeding beneath or within layers of the skin
    ecchymosis
  11. outermost layer of skin
    epidermis
  12. fibrous membrane covering that separates tissue from bone
    fascia
  13. burns that involve the entire thickness of the epidermis and dermis; also called 3rd degree burns
    full-thickness burns
  14. collection of blood beneath the skin
    hemmatoma
  15. burns that involve the epidermis and extend into, but not through, the dermis; also called 2nd degree burn
    partial-thickness burn
  16. outer layer of the eye
    sclera
  17. oily substance secreted by the sebaceous glands that help moisturize the skin
    sebum
  18. burns that involve the epidermis, the superficial layer, of the skin; also called first degree burns
  19. the term for no blood supply in refrence to the epidermis
    avascular
  20. whats the names and functions of the layers of the epidermis
    • Outer layer(keratin) = protective barrier to infection and prevents water loss
    • melanin = protects from the suns radiation
  21. names and functions of the layers of the dermis
    • 1. blood vessels=body temp reg., constrict to conserve heat, dialate to remove heat
    • 2. nerve endings=sensation
    • 3. sebaceous glands(sebrum)=moisterize
    • 4. sweat glands=temp reg., cool by evaperation
    • 5. hair follicles=guide sweat and sebum to the skins surface
  22. names and functions of the layers of the subcutaneous layer
    1. connecctive tissue and fat=insulation, stores energy (fat)
  23. small piece of skin normally holding on an avulsion
    pedicle
  24. a dressing that seals off and prevents air from entering the wound
    occlusive dressing
  25. the gel like fluid that fills the eye
    vitreous humor
  26. not transparent to light
    opaque
  27. the transparent membrane over the iris and pupil
    cornea
  28. the opening of the eye were light comes through
    pupil
  29. surrounding the pupil is the pigmented or colored portion of the eye
    iris
  30. the circulating watery fluid that filles the anterior portion of the eye
    aqueous humor
  31. when drainage of the aqueous humor is obstructed, pressure builds up and causes a condition known as:
    glaucoma
  32. the part of the body that is located at the superior lateral surface of each eye that secretes tears is:
    lacrimal glands
  33. what are the 3 main principles to remember when caring for an eye injury
    • 1. avoid pressure
    • 2. cover both eyes to limit movement

    malleus(hammer), incus(anvil), stapes(sturrup)
  39. the middle ear communicates with the nasopharynx by the:
    eustachian tube
