There are three bones, called ossicles, that carry sound vibrations from the eardrum to the inner ear. They are called the hammer, anvil, and stirrup (for their shapes). Their medical names are the malleus, incus, and stapes.

∙ 10y agoThere are three main sections of the ear, each with its parts and functions.
Outer ear - catches sound in stereo / Eardrum - vibrates to sound
Middle ear - transducer (from big motion to small motion)
Inner ear - original sound detector, converts motion of liquid to nerve impulses
Outer Ear:
- Pinna (also called auricle): It is outer most (and visible) portion of ear. Its external parts are wide while inner portion is narrow. Because of its shape it act as a funnel (collects the sound and directs it through ear canal to ear drum).
- Ear canal (auditory canal): It contains sebaceous glands which secrete ear wax (cerumen) for lubrication of ear.
- Eardrum (tympanic membrane): It is thin membrane located at the end of outer ear. It carries the sound towards middle ear.
Middle Ear
It consists of three ear bones or ossicles (malleus, incus and stapes). These ossicles transmit sound to the inner ear.
- Malleus (also called hammer): It is hammer like ossicle. Its one end is attached to ear drum while other is connected with incus.
- Incus (anvil): It is anvil shaped bone, attached with malleus and stapes.
- Stapes: stirrup shaped bone attached to incus and oval window or vestibular window (membrane covered opening between middle ear and inner ear).
Inner ear
It contains the cochlea, vestibule and semicircular canals.
- Cochlea: It is coiled portion and auditory portion of inner ear.
- Semi-circular canal: Three fluid filled canals horizontal semi-circular canal, posterior semi-circular canal and anterior semi-circular canal are called semi-circular canals.
The fluid inside these canals is called endolymph. The dilation at one end of canal is called ampulla. Ampulla contains Cupula and hair cells. Semi-circular canals are responsible for body balance and detect direction of rotation of head.
- Vestibule: It is located between the semi-circular canals and cochlea. Its anterior and inferior part has several minute holes for the passage of filaments of acoustic nerve (auditory nerve) to saccule. Saccule detects the motion of head when it moves vertically. At the upper and back of vestibule a structure called utricle detects the degree of tilt movement of head.

∙ 8y agoThe auditory ossicles (malleus, incus and stapes) in the middle ear are the smallest bones. They vibrate in response to tympanic membrane and carry sound and can amplify or damp it down. This is picked up by the auditory nerve and interpreted by the brain.

What are the three small parts of ears?
The different Parts of the Human EarThe three major parts of the human ear are the outer ear, the middle ear and the inner ear.Outer Ear: The outer ear consists of the following two parts:Ear Flap (Pinna)Ear Canal (Meatus)Middle Ear: consists of the following parts:Eardrum -HammerAnvil (Incus)Stirrup (Stapes)Inner Ear (Labyrinth): The inner ear comprises the following parts:CochleaSemicircular Canals -Auditory Nerve
What parts of the ear are responsible for hearing?
there are 3 part's... the outer ear, the inner ear, and the middle ear. all of these are responsible for hearing but the inner is for balance also.
Does The oval window separate the middle ear from the inner ear?
The oval window is part of the middle ear but in theory, yes it does separate the middle ear from the inner ear.
What part of the ear find eardrum?
The tympanic membrane (eardrum) separates the external ear from the middle ear
What is the middle ear cavity?
No. The vestibulocochlear apparatus belongs to the inner ear.
How many moving parts are in the human ear?
The middle ear, outer ear, and inner ear are the three parts of the ear.
What happens in a stapedectomy?
It is removal of parts of the middle ear and insertion of prosthesis parts
What are the three parts of the ear and what structures are located in each part?
You have external ear, middle ear and the internal ear. You have the auricle and the ear canal is there in the external ear. Then you have a ear drum, that separates external ear from the middle ear. In the middle ear, you have three tiny bones. Eustachian canal is there in the middle ear. Then you have oval and round window to separate the middle ear from internal ear. In the internal ear, you have vestibulocochlear apparatus and the vestbulocochlear nerve is there.

What are the parts of the physics human ear?
there are three main parts -outer -middle -inner
What are the functions of the three main parts of the human ear?
The three main parts of the ear are the outer ear, middle ear and the inner ear. The outer ear's function is to funnel or pass sound waves through the ear to the middle ear. The middle ear's function is to protect the inner ear from damaging sounds. In the inner ear, sound waves are converted into nerve impulses which are transmitted to the brain to be interpreted. The inner ear also serves as the main organ of balance for the body.

What three kinds of body parts do sound waves travel through before they reach the brain?
Outer ear, middle ear and inner ear
What two body parts are connected by the eustachian tube?
the eustachian tube connects the pharynx to the middle ear
What is Immittance testing?
It is made up of two parts, assessing the status of, and the protective mechanisms of the middle ear
When you are deaf what part is damaged?
When you are deaf multiple parts of the ear can be injured. The ear receives sound as vibration that it converts into sound that is understood by the brain. The parts of the ear that can be injured to result in deafness are the following: the eardrum, the cochlea, the auditory nerve and the middle ear ossicles. Damage to any one of these will result in deafness.
Does The oval window separate the middle ear from the inner ear?
The oval window is part of the middle ear but in theory, yes it does separate the middle ear from the inner ear.
