Smith 1,786 solutions Where do sound vibrations get transformed into neural signals?SOUND WAVES enter the ear canal and cause the eardrum to vibrate. VIBRATIONS pass through 3 connected bones in the middle ear. This motion SETS FLUID MOVING in the inner ear. Moving fluid bends thousands of delicate hair-like cells which convert the vibrations into NERVE IMPULSES.
Where do sound vibrations get transformed into neural signals that can be sent to the brain quizlet?The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.
What is the pathway of sound vibrations to the inner ear quizlet?First, the sound waves enter the ear through the pinna, then to the auditory canal, then the eardrum. Then this causes vibrations through the tympanic membrane, making the mallus, incus, and stapes to vibrate forcefully.
What structures in the ear line the basilar membrane and transmit neural messages to the brain?Once in the cochlea, the energy causes the basilar membrane to flex, thereby bending the stereocilia on receptor hair cells. This activates the receptors, which send their auditory neural signals to the brain.
