The
amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses. The auditory nerve sends these impulses to the brain.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.The tiny hair cells in our inner ear send electrical signals to the auditory nerve which is connected to the auditory centre of the brain where the electrical impulses are perceived by the brain as sound. The brain translates the impulses into sounds that we know and understand.

How is sound information transmitted to the brain for interpretation?

How are sounds transmitted to the brain?
Bending causes pore-like channels, which are at the tips of the stereocilia, to open up. When that happens, chemicals rush into the cells, creating an electrical signal. The auditory nerve carries this electrical signal to the brain, which turns it into a sound that we recognize and understand.
What are the 6 steps of hearing?

How does sound travel through the ear to the brain quizlet?
The inner ear has the cochlea which is a snail-shaped tube that is lined with receptors that respond to sound. The receptors are tiny hair cells that shake back and forth in response to sound waves. When they shake, the hair cells create nerve impulses which go to the brain along the auditory nerve.

How does sound travel from its source to your ear?
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.

Hearing and the cochlea – Health Video – MedlinePlus
Sound waves entering the ear travel through the external auditory canal before striking the eardrum and causing it to vibrate.
What is the correct path of sound through the ear to the brain?
The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses. The auditory nerve sends these impulses to the brain.
In what order does the ear process sound and deliver it to the brain?
We’ve put together a step-by-step explanation of how people hear—from the moment sound waves arrive to the outer ear, then travel through the middle and inner ear and transform into meaningful signals sent on to the brain. Our brain uses these signals to organize and communicate with the external world.

How do people perceive sound?
Sound and the Brain
While the ears are responsible for receiving sound from the environment, it is the brain that perceives and makes sense of these sounds. The auditory cortex of the brain is located within a region called the temporal lobe and is specialized for processing and interpreting sounds (see Figure 3).
What order does sound travel through the ear quizlet?
The eardrum vibrates from the incoming sound waves and sends these vibrations the malleus, incus, and stapes. The ossicles increase the sound vibrations and send them to the cochlea in the inner ear. Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane.
