Question

24 mark for review sound waves are converted into mechanical vibrations in the middle ear. these vibrations are eventually transduced into neural impulses when a the hair cells in the ossicle bones are bent against the eardrum in the middle ear b the oval window causes the hammer, anvil, and stirrup to move c the hair cells on the basilar membrane are bent in the cochlea d neurons in the auditory cortex fire an action potential

Explanation:

Sound - wave vibrations travel to the cochlea. Hair cells on the basilar membrane in the cochlea are bent by these vibrations, which then triggers the transduction of mechanical energy into neural impulses. The ossicle bones (hammer, anvil, stirrup) transmit vibrations from the eardrum to the oval - window but the transduction to neural impulses occurs in the cochlea with the bending of hair cells. Neurons in the auditory cortex process the neural impulses but the initial transduction is not there.

Answer:

C. the hair cells on the basilar membrane are bent in the cochlea
