Auricle: the structure of human, diagram and pictures
How does the human ear?
Ears to the complex structure of the human body, carrying important functions. He is responsible for taking sound waves and converts them into nerve impulses, transmission in the brain, and also for balance.
Despite the fact that paired organ seems simple in its structure, it has a complex anatomy, which includes the outer, middle and inner parts. In the case of penetration of microbes, and trauma of the organ of hearing, dysfunction of the hammer, anvil, stirrups and other elements. This leads to severe pain and other signs of delivering significant inconvenience.
Description the ear on
Human ears are distinguished by their complicated structure. When inflammation of the lost hearing acuity, as well as headaches and ear pain, feeling of heaviness in the ears, the patient is plagued by strange sounds. In some cases, appear purulent or bloody discharge.
These symptoms are caused by the malfunction of any part of ear on. To determine the root cause of any inflammation is impossible without knowledge how the human ear is.
There are three parts of the ear on:
This files most often occurs dysfunction of middle-sized region. It contains the auditory ossicles responsible for the processing and perception of sound frequencies, which are located behind the outer part and the drum region.
After the middle pane, and bones is the inner ear, localized in the cranial bones. Thanks to the continuous work of the data elements that a person perceives all frequencies from the low to high waves.
The outer ear
The external part of the ear that people see is called the auricle. In its region contains cartilaginous tissue, which has an elastic structure. Due to the presence of folds of skin and fat, this cavity is quite hard to injure and cause cracks.
However, when intensive cleaning ears or as a result of occupational exercise the body suffers the most. This breaks the primary structure, which causes the disease otitis or fungus.
The main function of the outer part – the reception and transmission of sounds of different frequencies. Further, the sound waves pass through the auditory canal, covered with folds. They help in the treatment of noises and sounds and transmit them further to the auditory ossicles.
Please note on the picture the outer part of the ear:
The structure of the ear is not complicated, but due to this structure, people can distinguish sounds at a considerable distance. So, if you ear healthy body, people can pick up sounds at a distance of about thirty meters.
In anatomy, the outer part of the ears includes the following elements:
- Curl and protivotumanok.
- Tragus and proteomelab.
In addition to the described elements in the outer body are sulfuric glands, bearing protection function. The so produced sulfur allows to neutralize bacteria, infections, small insects, and also protects the ear from foreign object ingress to the middle ear.
Sulfur is excreted from the ear on yourself when eating or communicating. However, once a week is necessary to clean the outside of the shell, as well as a daily to take water treatments. Otherwise in the ear canal can form a blockage that impedes the transmission of sounds and delivers a strong discomfort.
In this case, you must consult your doctor for ear cleaning and removal of cerumen. In some cases, allow independent removal of the tube. However, this is possible only if soft tube yellow color. In case of a persistent sulfur, which is found brown or black color, need expert help.
The middle ear
The design of the middle part of the ears has an exceptional origin. His device consists of the auditory ossicles, which convert the sound waves of different frequencies and transmit them to the inner ear.
The middle ear is localized behind the eardrum and ends in the vicinity of the temporal part of the head. In the middle part are elements such as:
- Mastoid process that connects the tympanic area and the temporal part.
- Located next to the eardrum, distinguishing the subtle structure.
- After the described region is Eustachian tube, which connects with the nasopharynx. That’s why people often suffer from inflammation of the middle pane.
Because the bacteria and infection often go through the nose or throat.
The main function of the Eustachian tube – the regulation of the internal pressure and control the incoming air. In case of violation of one of the three items causes an inflammation of the ear organ.
In addition to the elements described in the tympanic cavity of the person is located on the stapes.
Directly to the eardrum adjusts to the hammer. The main function of the auditory ossicles – analysis and the direction of the sounds and noises on the anvil.
Anvil, in turn, is in front of the stapes and transmits it already analysed the sound wave.
The stirrup sends the converted sounds and noises further direction.
In addition to these tasks, there are the following functions of the auditory ossicles:
- Continuous operation of the eardrum.
- Protecting the inner ear from high and great treble.
- Adjustment of the low waves.
- The perception of the organ of hearing any sounds.
A curious fact: it is known that the person picks up and analyzes sounds from twenty Hertz to twenty cherts. But over time, the upper limit decreases.
In the case of trauma or penetration of the viruses into the middle ear, the person experiences a shooting pain, pain in the head or the temples, as well as hearing loss or complete deafness.
In this case, should immediately contact the medical facility and to make independent measures. Thus, in the case of the use of different tinctures or drops in case of perforation of the eardrum you can lose hearing permanently.
The middle ear is connected with the Eustachian tube that is responsible for the regulation of pressure. Additionally, this area monitors the incoming air. In the case of pressure changes, for example, when flying or traveling in mountainous terrain, the Eustachian tube is very sensitive to changes. In this case the person feels congestion in the ears and a feeling of heaviness.
The inner part
This area is considered to be one of the most difficult in the ear on. Because of its unusual structure of the inner ear called the labyrinth. It includes the semicircular canals and the cochlea.
This area is localized in the temporal part of the head and is in contact with the middle ear via the round and oval Windows. The pattern of the labyrinth consists of the following elements:
- Semicircular canals.
In addition to the transmission of sound waves converted into nerve impulses, the body responsible for balance.
It is believed that the most important role in the structure of the internal area belongs to the snail. Its fluctuations lead to the creation of electrical impulses, which are transmitted via nerve impulses.

In the event of disruption of any part of the ear on there is a loss of sensitivity of the sounds, the appearance of stuffiness in the ears, a feeling of pain and other unpleasant symptoms. It is therefore necessary, with particular attention to the health of the body. Engage in prevention health.
