The process of hearing in the inner ear involves:

• The conversion of sound waves into electrical signals by the cochlea.

• The amplification of sound by the eardrum.

• The transmission of sound through the auditory canal.

• The reflection of sound waves by the outer ear.

How is the inner ear organized? The ________________ portion and the ____________ portion.

• vestibular, cochlear

• auditory, visual

• cerebral, spinal

• optic, olfactory

Which portion is involved with hearing?

• Cerebrum

• Cerebellum

• Temporal lobe

• Occipital lobe

The inner ear communicates with the middle ear through the ________________ and the ________________.

• oval window, round window

• eustachian tube, cochlea

• auditory canal, tympanic membrane

• semicircular canals, vestibule

Identify the three canals of the cochlea.

• Vestibular canal, Tympanic canal, Cochlear duct

• Eustachian tube, Semicircular canals, Cochlear duct

• Auditory canal, Tympanic canal, Vestibular canal

• Cochlear duct, Eustachian tube, Auditory canal

Fill out the table to describe the divisions of the cochlea.

• Scala vestibuli, Scala media, Scala tympani

• Scala anterior, Scala posterior, Scala lateral

• Scala superior, Scala inferior, Scala medial

• Scala proximal, Scala distal, Scala central

______________ is the sensory end organ of hearing and is located on the ______________ membrane in the scala _______________.

• Organ of Corti, basilar, media

• Organ of Corti, tectorial, vestibuli

• Organ of Corti, basilar, tympani

• Organ of Corti, tectorial, media

Fill out the table to compare and contrast Inner and Outer Hair Cells.

• Inner Hair Cells are primarily responsible for sound transduction, while Outer Hair Cells amplify sound.

• Inner Hair Cells amplify sound, while Outer Hair Cells are primarily responsible for sound transduction.

• Both Inner and Outer Hair Cells have the same function in the auditory system.

• Outer Hair Cells are responsible for sound transduction, while Inner Hair Cells amplify sound.
