Looks like the eardrum in your ear: photo
How does the eardrum?
The organ of hearing in humans is responsible for many of the factors necessary for natural life. In the case of injury, for example in active sports activities or in case of contact with bacteria and infections in the ear organ, the patient feels a sense of stuffiness, hearing loss or total deafness, and not the natural sounds, a squeak, a rustle, in severe cases dizziness and nausea.
Threat has always considered a violation of the integrity of the eardrum. In this article we take a closer look at the structure of the ear on, and looks like the eardrum in your ear, photos and videos.
It looks like the membrane in the ear
Drum area needed in the structure of the ear organ. It not only helps in the conversion of sound waves into nerve impulses, but also protects the ear from entry of water, foreign matter, and protects the auditory ossicles and the labyrinth from different viruses, harmful bacteria and dangerous infections.
Anatomically the tympanic area located in front of the auditory ossicles located in the middle region of the ear and ends in the inner part of the ear.
This area is particularly sensitive, since the membrane thickness is only 0.1 millimeter. By the way, the membrane itself is painted in a pearl color and has a very sensitive structure. Therefore, this region can capture sounds and noises with a frequency of from 15 Hertz to 25 khertz.
In the case of diseases of the ear organ, such as otitis or other inflammatory processes in the ears, the top indicator is significantly reduced. In the absence of proper treatment and ignoring the symptoms of inflammation can occur the absolute partial loss of hearing, or absolute deafness.
It is known that the membrane undergoes age-related changes. Thus, in infants the diaphragm has a circular shape, the children of adolescent age are more oval. In Mature people changing the diameter of this region.
In the biggest measurement she may be about ten millimeters, and the smallest circumference can be measured up to eight millimeters.
The strength of the membrane, its diameter and thickness in humans of advanced age varies.
In this regard, with aging many people experience hearing problems.
In this case, if hearing problems run, doctors prescribe hearing AIDS.
The membrane consists of several tissues:
- The outer region consists of the epidermis of the ear canal.
- Located next to the main membrane layer, which consists of various fibres radical and circulation tissue.
- The final layer, which is called inner, is formed from the mucous membrane of the tympanic cavity.
By using the above-described parts, the sound waves are converted into nerve impulses pass from the drum region Department of the interior ear, and then to the brain via the glossopharyngeal nerve.
The eardrum is located the drum area. It is a core in the middle cavity of the ear and takes up to one centimeter. It is believed that this area is the smallest in the structure of the ear on, but despite this, she has a complex structure.
This cavity is localized in the temporal bone of the skull, and attaches to this area using special rings. Therefore, the membrane is quite tight. Because of this, when the penetration of the viruses in this part of the person experiences severe shooting pains, not only in the ears but in the head.
The upper region is anchored to the bony part of the frame, but it is located quite freely.
The two remaining parts of the tympanic membrane contiguous with hammer folds, which are divided into two types:
- Front pleat.
The smallest part of the Malleus joins the membrane of the eardrum. Due to this structure, it is possible to catch different sound vibrations.
Inside the middle part of the ear on there is a constant pressure on the eardrum.
This pressure equals atmospheric, so the contact of air with the diaphragm it flexes.
At this time, to transmit sound pulses into the sound bone, in particular to hammer.
Man, in an aqueous medium, is experiencing a strong resonance, because the frequency sounds in the atmosphere is less than twenty Hz.
The ability to hear is due to the balance of external and internal pressure. For this opportunity meets the Eustachian tube, which regulates blood pressure.
But in the case of dysfunction of the body and with a strong change in the ambient pressure, the membrane is subjected to heavy trauma.
Usually this happens when heavy claps, explosions, and other sudden sounds that can greatly harm and even break the eardrum. At this time, the person experiences severe and sharp pain which can significantly impair hearing acuity, and even deny the ability to hear forever.
Sounds that can harm the membrane needs to be incredibly strong, as this area is durable and withstands the pressure up to a hundred millimeters of mercury.
In disorders of the tympanic membrane requires urgent treatment. In some cases, the membrane restores itself. In more complicated cases, subject to the damage of the main layer of the membrane require surgical intervention.
In severe cases, damage to the tympanic cavity is broken and damages the inner ear. In this case, the prognosis is extremely unfavorable. A person can lose their hearing permanently.

Additional information about the eardrum
As we have seen, the tympanic membrane in the ear is distinguished by its delicate structure. Membrane located in the cavity, does not pass air flow, and various viruses and infections. Through this area would not be able to pass small insects and other foreign objects.
A healthy and intact membrane has a translucent color, giving the pearl color. Through it when viewed with special devices it is possible to notice the hammer. This is a pretty important criterion in otoscopy examination of the ear and the body, as in the case of inflammation of the ear drum area that is heavily modified.
Therefore, the appearance of this region is of great importance in the diagnosis of various inflammatory processes in the organ of hearing.
Malleus attached to eardrum transmits the sound waves next to the anvil and the stirrup. After processing the sounds, nerve impulses pass to the inner ear, particularly the cochlea.
The snail is the curls of the channels. It is divided into several compartments with membranes.
In addition to these elements, the membrane is a transformer. The main task of the described region – the transfer and processing of the information into a nerve impulse that contains the electric potential. In the medical field this part of the eardrum is called kortieva body.
In inflammatory processes or in case of violation of the integrity of the eardrum, a person experiences severe pain. This causes a loss of appetite, the patient is deprived of sleep. In a separate but extremely rare cases, there is dizziness, nausea, bloody or purulent discharge.
During this period the patient is required to provide timely and comprehensive treatment, as the rupture of this area is considered quite dangerous.
In case of rupture of the tympanic membrane or the formation of various openings in this field, the person experiences hearing loss, loss of sharpness of the sounds and other symptoms.
Often perforation of the ear appear to be a case of purulent otitis media or acute inflammatory process. Another common reason for the appearance of holes in the ear – otitis media.
In any case, whether the ear infection, any infection or rupture of the membrane due to very loud sounds, needs urgent treatment.
It should be understood that perforations of this region has a negative impact not only on the state of the middle ear, but also on human health overall. In addition, problems with the diaphragm or membrane can cause severe inflammation of the labyrinth.
In connection with close internal Affairs to the brain, it can lead to meningitis and other dangerous diseases.
So try to take care of the condition of the ear in General, to conduct periodic hygiene and regular visits to the office of ENT.
