Which parts of the brain receive the impulses from the auditory nerve?
The auditory nerve sends impulses to the brainstem's cochlear nuclei, which then project to the auditory cortex in the temporal lobe. This is where sound processing and interpretation primarily occur.
What three kinds of body parts do sound waves travel through before they reach the brain?
Sound waves travel through the outer ear, then the middle ear, before reaching the inner ear where they are converted into electrical signals that travel to the brain through the auditory nerve.
What three general kinds of body parts do sound waves travel through before they reach the brain?
Sound waves travel through the outer ear, middle ear, and inner ear before they reach the brain. In the outer ear, sound waves are collected by the ear canal and directed to the eardrum. Then, in the middle ear, the sound waves cause the three tiny bones (hammer, anvil, and stirrup) to vibrate. Finally, in the inner ear, the vibrations are transformed into electrical signals that are sent to the brain via the auditory nerve.
What parts of the central and peripheral nervous system have to be functioning for the senses of hearing and vision?
For the sense of hearing, the central nervous system (specifically the auditory cortex in the brain) and the peripheral nervous system (including the auditory nerve and cochlea in the ear) must be functioning. For vision, the central nervous system (particularly the visual cortex) and the peripheral nervous system (including the optic nerve and retina in the eye) are necessary for proper function.
What part of the brain relays impulses between the brain and other body parts?
nerve
What parts in the ear assist in the ability to hear a sound wave from the time the sound enters the ear until it reaches the brain?
The auditory canal to the eardrum then the auditory nerve sends it to the brain for interpretation.
Does the auditory nerve have blood in it?
No. Nerves are not blood-filled. They are a bundle of fibers that carry information from parts of your body back to your brain, where your brain then processes that information.

What are the parts in the inner ear?
- Semicircular canals - Auditory nerve - Cochlea
What does the human auditory system look like?
The human auditory system consists of the outer ear, middle ear, inner ear, and auditory nerve. Sound waves are collected by the outer ear, amplified in the middle ear, and converted into electrical signals in the inner ear by tiny hair cells. These electrical signals are then sent to the brain via the auditory nerve for processing.
What is the structure of the nervous system?
Most of the neurons of the central nervous system are in the brain. The brain leads to a brain stem, which in turn connects to the spinal cord, from which nerve travel all over the body. There are also nerves which do not pass through the spine but which connect the brain directly to various parts of the head, including the optic nerve which goes to the eyes, and the auditory nerve which goes to the ears. In addition to the central nervous system there is also an autonomic nervous system which is centered in the solar plexus; it is kind of an auxiliary brain for the digestive system.

Does your brain have nerve endings?
No, the brain itself does not have nerve endings. Nerve endings are found in other parts of the body, such as the skin, that send signals to the brain.
Are there nerve endings in the brain?
No, the brain itself does not have nerve endings. Nerve endings are found in other parts of the body, such as the skin and organs, but not in the brain itself.
What parts of the ear anatomy belong to the inner ear?
Auditory canal, tensor tympani muscle, cochlea, cochlear nerve, vestibular nerve.
