What are the parts of middle and inner ear?
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 is the difference between inner and middle ear?
The inner ear is made up of the cochlea, the auditory nerve and the brain. The middle ear consists of the middle ear bones called the ossicles (malleus, incus, stapes). The outer ear includes the pinna, the ear canal and the eardrum.

- Inner Ear. The inner ear is made up of:
- The ear (auditory) Nerve.
What are the 3 bones in your ear called?
The middle ear contains three tiny bones: Hammer (malleus) — attached to the eardrum. Anvil (incus) — in the middle of the chain of bones. Stirrup (stapes) — attached to the membrane-covered opening that connects the middle ear with the inner ear (oval window)
What are 2 Functions of the middle ear?
It is classical to ascribe three functions to the middle ear: the transmission of acoustic vibrations from the tympanic membrane to the cochlea, impedance matching between the air in the external auditary meatus and the labyrinthine fluids, and protection of the inner ear by means of the acoustic reflex.
Is vertigo and tinnitus related?
Tinnitus and vertigo are very closely related. Tinnitus, which is very common, results in an intermittent or constant “ringing” sound in the ear. It may also be perceived as hissing, whistling, or buzzing. Severe tinnitus can result in additional symptoms like dizziness that affect one’s daily life.
What part of the ear controls balance?
The inner ear is home to the cochlea and the main parts of the vestibular system. The vestibular system is one of the sensory systems that provides your brain with information about balance, motion, and the location of your head and body in relation to your surroundings.
What are the 3 tiny bones in the middle ear?
The middle ear contains three tiny bones:
- Hammer (malleus) — attached to the eardrum.
- Anvil (incus) — in the middle of the chain of bones.
- Stirrup (stapes) — attached to the membrane-covered opening that connects the middle ear with the inner ear (oval window)
Can ear problems affect your eyes?
Inner-ear problems cause diverse symptoms such as vertigo, nausea and blurred vision.
Which is the smallest bone in ear?
the stapes
Once there, the sound waves vibrate three bones known as the ossicles, which are made up of the malleus, the incus, and the stapes. The stapes is the smallest bone in the human body.
How does fluid get into middle ear?
Normally, you release pressure in your middle ear when you swallow. Swallowing causes your eustachian tubes to open, which can happen 3 to 4 times per minute. If an eustachian tube is blocked, fluid builds up in your middle ear so that your eardrum can’t move the way it should.
What are the parts and functions of the middle ear?
The oval window is covered with a membrane and connects the middle ear to the vestibule of the internal ear.
What are the different parts of the outer ear?
auricle (cartilage covered by skin placed on opposite sides of the head)
What are the structures of the middle ear?
Outer ear – The outer ear comprises ear pinna,the external auditory canal and tympanic membrane or eardrum.
Where is the middle ear located?
The middle ear, also known as the tympanic cavity or the tympanum, is a pneumatized (air filled) region of the temporal bone that lies just medial to the tympanic membrane (ear drum) and lateral to the promontory (caused by the turns of the cochlea) of the ear.
