1. The brain is _____ to the abdomen - CORRECT ANSWER superior
2. The knees are ____ to the toes - CORRECT ANSWER superior
3. The ears are _____ to the nose - CORRECT ANSWER lateral
4. The knees are _____ to the toes - CORRECT ANSWER proximal
5. What ossicle connects with the tympanic membrane? - CORRECT ANSWER
malleus
6. Is the Eustachian Dude of a child or adult more horizontal? - CORRECT
ANSWER child
7. Which ossicle connects with the cochlea? - CORRECT ANSWER stapes
8. List the three ways in which the middle ear impedance matches - CORRECT
ANSWER 1) the lever action of the ossicles
2) the area ratio of the tympanic membrane to the ossicles
3) the buckling action of the tympanic membrane
,9. If you have a threshold of 25 dB with headphones and with the bone
oscillator, where is the hearing loss coming from? - CORRECT ANSWER The
inner ear and beyond because we didn't lose anything going through the
outer and middle ear with the headphones, or lose anything going right to
the mastoid bone and the cochlea
10.If you have a threshold of 50 dB HL for headphones and 35 dB HL for the
bone oscillator, where is the hearing loss coming from? - CORRECT ANSWER
The hearing loss is coming from the middle ear and beyond because the
threshold was higher when we bypassed the middle and outer ear, but it
was not a normal threshold with the bone conduction
11.What is mixed hearing loss? - CORRECT ANSWER Hearing loss from both the
outer and middle ear
12.What is sensorineural hearing loss? - CORRECT ANSWER inner ear or more
central hearing loss (cochlea being sensory and neural being nerve)
13.Which middle ear measurement involves testing a number of pathways
including the middle ear, cochlea, CNViI, CNVIII, and the brainstem? -
CORRECT ANSWER Stapedial reflex (known as the acoustic reflex clinically)
14.Which middle ear muscle has a greater effect on audition? - CORRECT
ANSWER stapedius muscle
,15.Which middle ear measurement measures the middle ear movement? -
CORRECT ANSWER Tympanogram
16.Cerumen (in appropriate quantities) is healthy for the ear: true or false? -
CORRECT ANSWER true
17.Approximately how much gain results from impedance matching through
the middle ear system? - CORRECT ANSWER 33 dB
18.Which of the three methods of impedance matching of the middle ear
system results in the most gain? - CORRECT ANSWER Area ratio
19.I am testing someone's hearing. Their thresholds are normal if I test with
the bone oscillator, but reduced (poorer) if I test with headphones. What
type of hearing loss does the patient have? - CORRECT ANSWER conductive
hearing loss
20.What part of the cochlea does the stapes connect with? - CORRECT
ANSWER oval window
21.When we talk about the area ratio for impedance matching, what two
structures are we referring to the areas of? - CORRECT ANSWER the malleus
and the stapes
22.The middle ear transfer function helps determine the shape of the? -
CORRECT ANSWER minimum audibility curve
, 23.Efferent nerve fibers - CORRECT ANSWER send feedback from the brain
24.Afferent nerve fibers - CORRECT ANSWER send feedback to the brain
25.Outer hair cells - CORRECT ANSWER -have 3 rows
-have W-shaped stereocilia
-have Type II afferent innervation
26.Inner hair cells - CORRECT ANSWER -have 1 row
-have U-shaped stereocilia
-have Type I afferent innervation
27.Type I nerve fibers - CORRECT ANSWER Many nerve fibers to one IHC
28.Type II nerve fibers - CORRECT ANSWER One nerve fiber to many OHCs
29.Scala media has: - CORRECT ANSWER endolymph
30.The scala vestibula and scala tympani has: - CORRECT ANSWER perilymph
31.The base of the cochlea: - CORRECT ANSWER registers high frequencies
32.The apex of the cochlea: - CORRECT ANSWER registers low frequencies
