  1. ear
    hearing and equilibrium (balance)
  2. nose
    smell and entrance for air into the body
  3. pharynx
    carries air to the larynx and trachea, and food and drink to the esophagus
  4. larynx
    speech
  5. trachea
    brings air to the lungs
  6. adenoid/o
    • adenoids
    • one of three pairs of tonsils located in pharynx, also called pharyngeal tonsils; tonsils house large number of white blood cells that protect body by removing foreign invaders from air, food, and drink passing through pharynx
  7. audi/o
    hearing
  8. audit/o
    hearing
  9. aur/o
    • ear
    • responsible for hearing and equilibrium, divided into external, middle, and inner ear
  10. cochle/o
    cochlea
  11. epiglott/o
    epiglottis
  12. laryng/o
    • larynx (voice box)
    • located between pharynx and trachea; contains vocal cords that vibrate as air passes through them to produce sound
  13. myring/o
    tympanic membrane (eardrum)
  14. nas/o
    nose
  15. ot/o
    ear
  16. pharyng/o
    pharynx (throat)
  17. rhin/o
    nose
  18. sinus/o
    sinus
  19. tonsill/o
    tonsils
  20. trache/o
    • trachea (windpipe)
    • tube that carries air from larynx to lungs; lined with mucous membrane that warms, moisturizes, and cleanes air
  21. tympan/o
    tympanic membrane (eardrum)
  22. gastr/o
    stomach
  23. myc/o
    fungus
  24. neur/o
    nerve
  25. py/o
    pus
  26. -osmia
    smell
  27. -phonia
    voice
  28. -plegia
    surgical repair
  29. -sclerosis
    hardening
  30. -stenosis
    narrowing
  31. a-
    without
  32. an-
    without
  33. de-
    without
  34. dys-
    difficult
  35. endo-
    within
  36. pan-
    all
  37. para-
    alongside
  38. pinna (auricle)
    • captures sound waves and funnels them into external auditory canal
    • lump of external skin and cartliage making up ear on side of head
  39. tympanic membrane
    • eardrum
    • vibrates when struck by sound waves, vibration moves to three tiny bones in middle ear
  40. external auditory canal
    hole leading into inside of ear
  41. malleus, incus, and stapes
    the three tiny bones (ossicles) in middle ear, conducts vibration across middle ear from tympanic membrane to oval window
  42. oval window
    membrane covered opening, movement initiates vibrations in fluid inside inner ear, vibrating fluid bends hair cells in cochlea, stimulating nerve endings
  43. cochlea
    part of inner ear containing hair cells responsible for hearing; shaped like a coiled snail shell
  44. auditory nerve
    sends message to brain from nerve endings stimulated by hair cells
  45. semicircular canals
    organs for equilibrium in inner ear
  46. epiglottis
    cartilage flap that sits above larynx; rotates to cover larynx with each swallow; prevents food or drink from entering larynx and trachea
  47. acoustic neuroma
    benign tumor of auditory nerve sheath; symptoms include tinnitus, headache, vertigo, and progressive hearing loss
  48. cochlear implant
    hearing device surgically placed under skin behind ear; converts sound signals into magnetic impulses to stimulate auditory nerve
  49. croup
    acute respiratory condition common in infants and children; symptoms include barking cough
  50. deafness
    inability to hear or having some degree of hearing impairment
  51. decongestant
    medication to reduce nasal and sinus stuffiness and congestion
  52. diphteria
    bacterial upper respiratory infection; characterized by fomation of thick membranous film across throat and high morality rate; rare now due to DPT vaccine
  53. endotracheal intubation
    • (ET)
    • inserting tube through mouth and into trachea; creates open upper respiratory airway
  54. epistaxis
    nosebleed
  55. hearing aid
    device used by persons with impaired hearing to amplify sound; also called an amplification device
  56. otitis externa
    • (OE)
    • external ear infection; commonly caused by fungus; also called otomycosis; commonly known as swimmers ear
  57. otitis interna
    inflammation of inner ear; can affect both hearing and equilibrium; also called inner ear infection
  58. otitis media
    • (OM)
    • bacterial or viral infection of middle ear; common in children; often preceded by upper respriatory infection during which pathogens move from pharynx to middle ear through eustachian tube, commonly refered as a middle ear infection
  59. pertussis
    bacterial infection of upper respiratory system; rare now due to DPT vaccine; commonly called whooping cough due to whoop sound made when coughing
  60. tinnitus
    ringing in the ears
  61. vertigo
    dizziness
  62. DPT
    diphtheria, pertussis, and tetanus
  63. ENT
    Ear Nose Throat
