Ishihara plates

43
Q

instrument for examining the interior of the ear, especially the eardrum, consisting essentially of a magnifying lens and a light

A

otoscope

43
Q

Assessment of the ear includes:

A
  1. direct inspection and palpation of the external ear
  2. inspection of the internal parts of the ear by an otoscope

44
Q

In brief, sound can be transmitted by _____ or ________

A

air conduction or bone conduction.

44
Q

The external ear canal is curved, is about ______

A

2.5 cm (1 in.)

44
Q

Air-conducted transmission occurs by this process:

A
  1. A sound stimulus enters the external canal and reaches the tympanic membrane.
  2. The sound waves vibrate the tympanic membrane and reach the ossicles.
  3. The sound waves travel from the ossicles to the opening in the inner ear (oval window).
