One may also ask, what are the most important parts of the ear? The ear is made up of three parts: the outer, middle, and inner ear. All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear. Ears also help to maintain balance.

Hereof, what are the parts of the ears?

The parts of the ear include:

  • External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear.
  • Tympanic membrane (eardrum). The tympanic membrane divides the external ear from the middle ear.
  • Middle ear (tympanic cavity), consisting of: Ossicles.
  • Inner ear, consisting of: Cochlea.

What are the three small bones of the ear?

Ear bone, also called Auditory Ossicle, any of the three tiny bones in the middle ear of all mammals. These are the malleus, or hammer, the incus, or anvil, and the stapes, or stirrup.

What is the medical term for ear?

Here is how the ear works normally:
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move.

Where is the bone in your ear?

The three bones are called the malleus, incus and stapes and they sit in your middle ear (the part between the eardrum and the cochlea).

What is the middle ear for?

The middle ear is the part of the ear between the eardrum and the oval window. The middle ear transmits sound from the outer ear to the inner ear. The middle ear consists of three bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes), the oval window, the round window and the Eustrachian tube.

What is the pinna?

The pinna is the only visible part of the ear (the auricle) with its special helical shape. It is the first part of the ear that reacts with sound. The function of the pinna is to act as a kind of funnel which assists in directing the sound further into the ear.

What is eardrum job?

Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles.

It is spanned by a chain of three tiny bones—the malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.

How do we hear for kids?

The inner ear - The inner ear is filled with fluid and has the hearing organ called the cochlea. This organ helps to take the vibrations and translate them into electrical signals for the nerve to send to the brain. It actually uses little hairs that vibrate with the sound waves in the fluid. Then you "hear" it.

How does ear help in balancing?

The semicircular canals of the inner ear help you with balance. This movement of the fluid moves the hairs of the canals, creating nerve impulses that travel up to your brain and let it know that your head is off balance. You don't fall over because your brain tells your muscles to support you.

What does the inner ear look like?


The middle ear consists of the eardrum (tympanic membrane) and the auditory bones (ossicles) - the incus, malleus, and stapes. The inner ear consists of the fluid-filled semicircular canals, snail-shaped cochlea, vestibular nerve, and auditory nerve.
