What are the major parts of the ear?

Answer 1

The ear consists of three parts. The outer part, the middle part and the inner part. in the outer part there is the ear canal, in the middle part of the ear is the eardrum the hammer the anvil and the stirrup also the semicircular canals are in the middle part of the ear. and finally in the inner part of the ear is the cochlea and the auditory nerve.

Answer 2

The human ear has three main sections, which consist of the outer ear, the middle ear, and the inner ear. Sound waves enter your outer ear and travel through your ear canal to the middle ear. The ear canal channels the waves to your eardrum, a thin, sensitive membrane stretched tightly over the entrance to your middle ear. The waves cause your eardrum to vibrate. It passes these vibrations on to the hammer, one of three tiny bones in your ear. The hammer vibrating causes the anvil, the small bone touching the hammer, to vibrate. The anvil passes these vibrations to the stirrup, another small bone which touches the anvil. From the stirrup, the vibrations pass into the inner ear. The stirrup touches a liquid filled sack and the vibrations travel into the cochlea, which is shaped like a shell. Inside the cochlea, there are hundreds of special cells attached to nerve fibers, which can transmit information to the brain. The brain processes the information from the ear and lets us distinguish between different types of sounds.

Answer 3

The Human ear consists of 3 parts: the Outer Ear, the Middle Ear, and the Inner Ear.

The Outer Ear: The visible part of the ear. It is specially shaped to help guide sound waves into the ear to aid in processing what a person hears. Its main parts are the ear flap- where sound enters, and the ear canal- where sound is amplified on the way to the middle ear.

Middle Ear: This area of the ear takes sound vibrations and transforms them into energy that can be used by the body to process a sound. Parts include:

The Eardrum- A membrane that vibrates when struck by sound waves, turning them into mechanical or 'movement' energy.

Hammer- A tiny bone (the Malleus) that is vibrated by the new energy created by the eardrum. The hammer vibrates and passes the energy along to the next part.

Anvil- Another bone (the Incus) that moves with energy from the hammer.

Stirrup- Tiny bone (Stapes) that sends these vibrations to the inner ear where it will be processed into 'sounds' as the brain perceives them.

The Inner Ear: This is where vibrations are transformed into what humans perceive as sound.

Parts include:

Cochlea- A tube in the shape of a spiral that houses nerve cells that act like fine hairs. Different kinds of vibrations make them react differently, and they transmit electrical signals depending on the type of vibration being produced.

Semicircular canals- Three loops that have motion-sensing ability to maintain your balance. They are filled with fluid, and when the fluid changes direction, the changes are detected by tiny hairs (cilia). When movement is indicated by the hairs, an electrical impulse is sent to the brain to tell it that a person's body has changed direction/orientation.

Auditory nerve- This is the nerve that goes from the ear to the brain, sending along the electrical impulses generated by the other parts of the inner ear.
