What are the three parts of the ear

external, middle, and inner ear

how To assess the external ear structures and what do the external structures consist of

inspect and palpate external ear structures, which consist of the auricle, outer ear canal, and tympanic membrane (eardrum)

How to assess the middle ear and what structures does it consist of

air filled cavity containing the three bony ossicles

an otoscope

malleus, incus, stapes

Eustachian tube connects what and does what

connects the middle ear to the nasopharynx

pressure between the outer atmosphere and the middle ear is stablized

How is the inner ear tested and what does it contain

by measuring the patient's hearing acuity. inner ear contains the cochlea, vestibule, and semicircular canals

The upper point of attachment for an auricle is where and what does low set or an unusual angle are a possible sign of what

Upper point is in a straight line with the lateral canthus or corner of the eye

The position is almost vertical

ears that are lows set or unusual are a sign of chromosome abnormality such as Down syndrome

Auricle color red and pallor can be a sign of what

red - fever or inflammation

pallor/white- frostbite


a yellow waxy substance

yellow or green foul smelling discharge indicates what

infection or a foreign body

If hearing loss is suspected do what

check response to whispered voice test one ear at a time while the patient occludes the other ear with a finger. Ask him or her to gently move the finger up and down during the test in response to the whispered sound. then while standing 1-2 feet from the testing ear, speak while covering the mouth so the patient is unable to read lips. After exhaling fully, whisper softly toward teh inoccluded ear, reciting random numbers with equally accented syllables like 9/4/10. if necessary gradually increase voice intensity until patient is able to recite numbers correctly. Then test the other ear

Weber's test (lateralization of sound)

Hold fork at its base and tap it lightly against heel of palm

place base of vibrating fork on midline vertex of patients head or middle of forehead

ask patient if he or she hears the sound equally in both ears or better in one ear

Rhinne test (comparison of air and bone conduction)

place stem of vibrating tuning fork against patient's mastoid process ask patient to tell you when he or she no longer hears the sound, note number of seconds. Quickly place still vibrating tines 1/2 to an inch from ear canal and ask patient to tell you when he or she no longer hears the sound. continue counting time the sound is heard by air conduction. compare the number of seconds the sound is heard by bone conduction versus air conduction. patient should hear air conducted sound twice as long as bone conducted sound

Cranial nerves mnemonic for function

Some say marry money, but my brother says bad bitches matter more.

what the nerves do

I olfactory (smell)

II optic (sight)

III occulomotor (movement of eyes)

IV trochlear (eye movement)

V trigeminal (sensory functions related to nose eyes tongue and teeth)

VI abducens (turns eye laterally)

VII facial (face)

VIII vestibulocochlear (balance)

IX glossopharyngeal (tongue, throat, swallowing food)

X Vagus (throat and tasting)

XI Spinal accessory (spine)

XII Hypoglossal (muscles of the tongue)
