(B) The process of hearing involves the transmission of sound waves through the ear. $1$. Sound waves enter the external ear and strike the tympanic membrane. $2$. These vibrations are transmitted through the ear ossicles (malleus,incus,and stapes) to the oval window. $3$. The vibrations from the oval window are passed into the fluid of the cochlea,creating waves in the perilymph. $4$. These waves induce ripples in the basilar membrane,which move the hair cells of the Organ of Corti against the tectorial membrane,generating nerve impulses. $5$. Finally,the excess vibrations are dissipated through the round window (fenestra rotunda) into the middle ear cavity. Thus,the vibrations of the sound waves finally open into the round window.
