Auditory

Which is responsible for the matching of impedance between soundwaves in the air to the fluid in the cochlea?

• Tympanic Membrane and Ossicles

• Tympanic Membrane and Tensor Tympani

• Organ of Corti and Ossicles

• Organ of Corti and Tensor Tympani

A protective mechanism in which the intensity of loud sounds reaching the ear is decreased.

• Impedance Matching

• Place Principle

• Sound Attenuation

• Volley Principle

The tensor tympani tenses the ear drum to transmit the

sound to the ossicles is innervated by_______

• Vestibulocochlear Nerve

• Facial Nerve

• Abducens Nerve

• Trigeminal Nerve

True about Depolarization EXCEPT

• Reticular fibers move inward toward the modiolus

• Bending towards the long stereocilia.

• Bending away the long stereocilia.

• Basilar fiber moves upward.

Patients who suffered from a conductive hearing loss may experience the following EXCEPT:

• problem with the middle ear

• problem with the external ear

• impaired ability to hear certain pitches

• impaired ability to hear at all sound frequencies

A test for lateralization

• Weber's Test

• Rinne's Test

A (+) Weber on the (L) means _______

• the sound is not heard on the left ear

• the sound is heard on the left ear

A (-) Rinne's Test is

• indicative of a Unilateral sensorineural hearing loss

• indicative of a conductive hearing loss

• Air conduction is greater than bone conduction

• A problem in CN 8

TRUE OR FALSE: Without the ossicular membrane and the cochlea, sound waves can still travel to enter

the cochlea at the oval window but the sensitivity for hearing will be less than usual.

• TRUE

• FALSE

Do you believe that the ear is the avenue to the heart? :)
