Question
Chapter 50, Problem 4TYK
Summary Introduction
Introduction: Tympanic membrane transmits the air to the three bones that are located in the middle ear and to the oval window. In perilymph pressure, waves are produced by these structures, and these waves pass through a tympanic canal to the vestibular canal.

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.
