• perilymph and endolymph

Multiple Choice

Which of the following statements is true regarding hearing?

• air waves cause vibrations in the tympanic membrane which moves the malleus, incus and stapes on a pivot which, in turn moves the fluid within the vestibule moving hair cells in the crista ampullaris

• air waves cause vibrations in the tympanic membrane which moves the malleus, incus and stapes on a pivot which, in turn moves the fluid within the cochlea moving hair cells in the organ of Corti

• air waves cause vibrations in the tympanic membrane which moves the malleus, incus and stapes on a pivot which, in turn moves the fluid within the cochlea moving hair cells in the maculae

• air waves cause vibrations in the tympanic membrane which moves the malleus, incus and stapes on a pivot which, in turn moves the fluid within the vestibule moving hair cells in the organ of Corti

Multiple Choice

Multiple Choice

What happens in the inner ear? 

• Sound waves are captured.
• Sound waves move deeper into the ear. 
• Sound waves are reflected.
• Sound waves are converted into nerve impulses.
