Sensory Organs - Ear

What structure of the ear is responsible for capturing sound waves and funneling them toward the ear?

• Cochlea

• Tympanum

• Pinna

• Eustachian Tube

What is the last step of the hearing process?

• Eardrum vibrates

• Impulses sent to the vestibulocochlear nerve

• Round window dissipates vibrations within the cochlea

• Stapes hit the oval window and transmits vibrations to the cochlea

What structure of the ear is D

• Auditory tube (Eustachian tube)

• Cochlea

• Auditory Ossicles

• Organ of Corti

What is the function of Semicircular Canals?

• To sense equilibrium

• To sense sound

• Connects the middle ear to the throat to help maintain air pressure

• Amplifies sound waves so sounds waves are strong enough to interpret once they reach the Cochlea

The middle ear contains (select all that apply)

• Tympanum

• Organ of Corti

• Auditory Ossicles

• Pinna

What structure of the ear is C?

• Vestibulocochlear Nerve

• External Acoustic Meatus

• Tympanic Membrane

• Semicircular Canals

The inner ear contains all EXCEPT?

• Eardrum

• Cochlea

• Semicircular Canals

• Organ of Corti

What structure has hair cells that detect vibrations depending on the frequency of sound that is being received?

• Malleus

• Oval window

• Cochlea

• Organ of Corti

What is the primary function of the tympanic membrane?

• Vibrate when sound waves are received and move ear ossicles

• Dissipate sound waves

• Amplify sound waves

• Act as a barrier to the inner ear from outside objects

Why do some children have tubes placed in their ears?

• To help expand the ear canal

• To drain fluid away from the inner ear

• To help maintain pressure

• To help sound waves travel through the tympanum
