Otic changes with age - ANSWER -Skin and Canal become dry and
itchy
-Cerumen has decreased production and becomes dry

Otoscope - ANSWER An instrument for examining the external canal
and tympanic membrane of the ear
Audiometry - ANSWER Measurement of hearing acuity at various
sound wave frequencies
, Caloric Test - ANSWER assessment using different water temperatures
to assess the vestibular portion of the nerve of the inner ear (acoustic
nerve) to determine if nerve damage is the cause of vertigo
