Students have asked these similar questions
which statements are true about the Auditory Function
a. Sound waves are funneled by the auricle down the external acoustic meatus, causing the tympanic membrane to vibrate.
b. The tympanic membrane vibrations are passed along the auditory ossicles to the oval window of the inner ear.
c. Movement of the stapes in the oval window causes the perilymph, vestibular membrane, and endolymph to vibrate, producing movement of the basilar membrane.
d.Movement of the basilar membrane causes bending of the stereocilia of inner hair cells in the spiral organ.
which statements are true about the Auditory Structures and their Functions
a. The middle ear is connected to the mastoid air cells.
b. The inner ear has three parts: the semicircular canals; the vestibule, which contains the utricle and the saccule; and the cochlea.
c. The cochlea is a circular-shaped canal within the temporal bone.
d. The cochlea is divided into two compartments by the vestibular and basilar membranes. The scala vestibuli and scala tympani contain perilymph. The cochlear duct contains endolymph and the spiral organ (organ of Corti).
which statements are true about the Auditory Structures and Functions
a. The external ear consists of the auricle and external acoustic meatus.
b. The middle ear connects the external and inner ears. The tympanic membrane is stretched across the external acoustic meatus.
c. The malleus, incus, and stapes connect the tympanic membrane to the oval window of the outer ear.
d. The auditory tube connects the middle ear to the pharynx and functions to equalize pressure.

- Jill is diagnosed with sensorineural deafness, a disorder in which sound waves are transmitted normally to the inner ear but they are not translated into neural signals that travel to the brain. Sometimes the cause is a problem with the auditory nerve, but in Jills case it has to do with a problem in the inner ear itself.
