  49. Weber test - tests what? describe
    Normal result
    Sensorineural vs. conduction hearing loss - where is sound louder for each?
    • Test for auditory acuity of Vestibulochoclear nn (CN VIII)
    • Tests for lateralization of sound
    • Place vibrating fork to center of forehead
    • Normal - Sound heard = on both sides
    • Sensorineural loss - sound louder in normal ear (sound localizes to opposite ear w/intact nn)
    • U/L conduction loss - sound lateralizes/louder in deceased ear
  50. Rhinne test - Normal result
    (+) vs (-)
    Sensorineural vs. conduction hearing loss
    • Normal - Air conduction (fork outside ear) is better than bone conduction (mastoid)
    • (+) = AC > BC = sensorineural deafness
    • (-) = BC > AC = conductive deafness
  51. Rhinne test - tests what? describe (4 steps); graded how?
    • Test for auditory acuity of Vestibulochoclear nn (CN VIII)
    • Compares bone conduction (BC) vs. air conduction (AC)
    • Vibrating tuning fork is placed against mastoid process
    • Pt indicates when sound no longer heard
    • Fork is moved to external auditory meatus (near ear)
    • Pt states whether sound is heard here
    • (+) or (-)
  52. Function of CN VIII
    • Auditory acuity - sensorineural vs. conduction hearing loss
    • Vestibular
    • Vestibulocochlear nn

    • SCM - rotate head to L & R
  57. Pathology of CN XII - Central vs. Peripheral
    • Peripheral - Tongue deviates TOWARD side of lesion w/atrophy & fibrilations
    • Central - Tongue deviates AWAY from side of lesion w/o atrophy or fibrulations
  58. Test for CN XII
    • Hypoglossal nn
    • Pt sticks out tongue & moves it side to side
  59. Function of CN XII
    • Hypoglossal nn
    • Tongue movement
