What are the functions of the ear in addition to hearing?

What can the ear perceive besides hearing?

The ear is one of the important organs of the human body, located behind the eye, and it has the function of receiving sound waves, which can be transmitted to the brain by transmitting the received sound waves into nerve signals. These signals are then translated into other sounds that we can understand, which is the auditory system.

So what can the ear perceive besides hearing?

The answer to this question seems simple, what does the ear care about listening? Actually, this is not comprehensive. Because in addition to the well-known auditory function, the ear has another important function that people don't know much about, and that is the balance function, which is what otolaryngologists and neurologists often refer to as "vestibular function".

Why don't people stagger, don't fall when they're upright? Why don't you bump into obstacles or other people when walking? Why is it that you can reach out and get what you want to pick up quickly and accurately?

Why can the eye see the outside world accurately and clearly? This is because the human body has a sound balance system that enables people to adapt to the external environment and adapt to the needs of survival. The normal function of the front of the ear plays the most important role in maintaining the balance of the human body.

Therefore, the human ear has two important functions, that is, auditory function and vestibular function.

The human ear is mainly divided into three parts: the outer ear, the middle ear, and the inner ear.

The external ear includes the auricular and the external auditory canal, and the function of the pinna is to collect sound, locate and amplify sound; The function of the external auditory canal is to conduct sound, resonate to amplify sound, buffer sound in the S-shaped direction, and collect sound from the inner ear.

The middle ear includes the tympanic membrane, the ossicular chain, and the Eustachian tube. The role of the middle ear: it has the effect of transducing and amplifying sound energy.

The inner ear includes vestibule, semicircular canals, and cochlea. The role of the inner ear: the vestibular and semicircular canals play a role in maintaining the balance of the body, and the cochlea is mainly a function of sound transmission and sensory sound (perceiving sounds of different frequencies).

The vestibular and semicircular canals in the ear are the position receptors that sense the change of the position of the head, which has the effect of maintaining the balance of the human body, and motion sickness and seasickness are also related to these two organs.

It will keep the human body balanced, and it is also a receptor for sense of position, which can collect sound waves, transmit information to the brain, allow the body to respond quickly, can play a certain aesthetic role, can wear masks, can wear sunglasses, and plays a fixed role.

You can feel balance, and your ears are also tactile, you can feel the situation around you, which can help people maintain better balance and better understand the situation around them.

Effectively balance the body, effectively perceive the awareness of space, increase happiness, and can effectively increase the three-dimensional sense, making our facial features more symmetrical and looking very beautiful and generous.

What can the ear perceive in addition to hearing? The ear has two important functions, one is to collect sound information. If you lose your hearing, you will enter a silent world.

As the saying goes: one deaf and three stupid! You can see the importance of listening.

The second function is to maintain the balance of the human body. If you walk in the dark or close your eyes and don't fall, your ears are at work. We have five senses in our body, including hearing, and physical strength is also very important for people.

It should be said that the five senses are very important to the human body and are indispensable parts to ensure the normal life of the human body. If you want to have good hearing, you need to make sure that there are no problems with your ears. The role of the ear is to listen to the information from the outside world, and then transmit the information to the brain, which then gives instructions to the body, and the normal life can function.

In addition to listening to sounds, people don't pay much attention to it, because it looks relatively inconspicuous. Although it is inconspicuous, it is more sensitive, and as long as there is a problem with the body, the ears can be reflected.

The ear is located behind the eye and has the function of recognizing vibrations, converting the sound emitted by the vibrations into nerve signals that are then transmitted to the brain. In the brain, these signals are translated into words, ** and other sounds that we can understand. Because people have ears, they can distinguish between various natural and biological phenomena; You can hear the strange sounds of the world and feel sacred.

The ear is one of the important organs of the five senses, which has the function of distinguishing vibrations, and can convert the sound emitted by vibrations into nerve signals, which are then transmitted to the brain. In the brain, these signals are translated into words, ** and other sounds that we can understand. In addition to being in charge of hearing, it also has the function of maintaining the balance of the body.

Thus, our ears determine the state of tension in the body – that is, the distribution of different states of tension and relaxation in different parts of the body. Our ears affect the thermal balance of the organs, which regulates the blood flow of the eardrum from the blood circulation and is directly linked to the thermoregulatory center of the brain. Medical resonance studies have shown that specific structures can alter thermal regulation.

However, thermoregulation has a very important role in defeating diseases, for example, fever, which we are very familiar with. Our ears are connected directly to our auricular foramen through nerve pathways and many vital organs, and the neural management of the pinna and tympanic membrane is mostly influenced by the tenth cranial nerve, the so-called vagus nerve. As important neuromanagers, this pair of cranial nerves is associated with the throat, bronchi, heart, stomach, pancreas, liver, kidneys, small intestine, and solar plexus.

It also has a definite role in eliciting physiological responses to stress. In this way, our ears form a transmission chain with vital organs through the vagus nerve, which directly affects the regulation of stress.

The vestibular and semicircular canals in the ear sense the position of the head, and the position receptors that maintain the body's balance function. The semicircular canals can feel the rotational and variable speed movement of the head.

It sounds ridiculous that your ears can still feel happy, but in fact, if you're in a happier mood, the shape of your ears will change somewhat.

You can also feel balance, because the ears are able to keep the balance of the human body. Without our ears, we may walk crookedly.

Balance.

The vestibular and semicircular canals in the ear are the position receptors that sense changes in the position of the head, and have the effect of maintaining the balance of the human body, and motion sickness and seasickness are also related to these two organs.

The range of mechanical waves that can be heard by the normal human ear is 20Hz to 20000Hz, and the most sensitive band is 100Hz to 400Hz, i.e.

The wavelengths of sound in the band range are different, and different wavelengths are received by nerve cells (hair cells) in different areas of the cochlea that are sensitive to different wavelengths, and form the sense of hearing.

Auditory formation of the ear

Hearing is accomplished by the combined activity of the ear, the auditory nerve, and the auditory center. The ear is the peripheral sensory organ for hearing and positional (balance). The ear is composed of a microphone composed of the outer ear and the middle ear, and an inner ear sensory and balancer.

The outer ear is exposed on the surface of the body, the middle and inner ears are buried in the petrous part of the temporal bone, the outer ear and middle ear are the conduction organs of sound waves, and the inner ear has receptors for sound and positional sense, which are the main parts of the hearing and positional sensory organs.

Sound waves are transmitted to the inner ear through the external auditory canal, eardrum, and ossicles, which excite the sensory organs of the inner ear (Coti's organs), and convert sound energy into nerve impulses, which then pass through the auditory nerve and enter the center to produce hearing.

The cochlea has two main functions: "sound transmission function" and "sound sensing function". Clause.

1. Sound transmission function, that is, the sound received by the vestibular window is transmitted to the hair cells, and when the stapes moves inward, the cochlear membrane protrudes outward, resulting in a pressure difference between the vestibular step and the tympanic step, and then causes the vibration of the base membrane.

Second, the sensory function, that is, the conversion of the sound energy received by the spiral into the potential of the cochlear nerve. The inner edge of the basal membrane is attached to the bone spiral plate, and the inner edge of the operculum is connected with the spiral plate edge, and the attachment point of the eardrum is not on the same axis, so when it occurs staggered displacement shear movement, a shear force is generated between the basement membrane and the operculum, under the action of shear force, the cilia of the hair cell are bent or deflected, causing the hair cell to be excited, and the mechanical energy is converted into bioelectric energy, and the impulse attached to the bottom of the hair cell to the cochlear nerve ending.

Can <> ear perceive balance in addition to auditory function? How can we protect our ears? People are very concerned about their eyesight and know how to protect it, but many people often neglect to protect their hearing.

If you have hearing loss, you will also feel inconvenient in your life, adding a lot of difficulties and troubles, especially for teenagers, hearing loss will affect their academic performance. Therefore, it is extremely important to maintain good hearing. Medical experts point out that paying attention to the following points can be very helpful in protecting hearing; Daily Hearing Protection:

Stay away from too noisy environments, don't stay too long in a noisy environment, use noise-emitting earplugs, don't listen to headphones for more than an hour every day, avoid noise exposure, drug allergies, pay attention to healthy diet, exercise more, and maintain a good mood.

It is necessary to master some relevant knowledge of ear protection to prevent ear diseases and bring adverse effects on life. Keep your ears clean and dry, keep your living environment quiet, comfortable, away from noise, don't wear headphones for a long time and be in a noisy environment for a long time. Pay attention to a reasonable diet, get enough rest, relax your mind, and strengthen exercise to improve your own immunity.

Do not get foreign objects into the ears, and pay special attention when washing your hair and bathing; In addition, do not often go to too noisy places, too noisy environment will cause dry sound deafness; In addition, do not go outside to irregular places such as barber shops to pick your ears, which is easy to cross infection; Finally, the elderly or friends with hearing loss can prevent hearing loss by exercising frequently to enhance their physical fitness.

It is recommended not to use hard objects to pluck your ears frequently, use cotton swabs in time when your ears are watered when you take a bath and wash your hair, it is recommended to bring earplugs for swimming, do not often go to noisy places, the auditory nerve is easy to fatigue in the case of noise for a long time, eat lightly, do not drink too much, some drugs will harm the ears, ask the doctor clearly when seeking medical treatment, and you can often do ear maintenance exercises. Maintain a happy mood, don't be too stressed, and stay up late.

In addition to hearing, the ears can also perceive balance, so we should protect our ears, don't let water get into the ears, don't let the ears hear too loud sounds, and don't wear headphones often.

Be sure to prevent water from entering the ears, mainly when taking a bath, you should pay attention to the water immediately with a paper towel or water absorber, and of course, do not go unwashed for a long time. Washing the ears can remove the dirt inside, so that we can hear more clearly, the dirt in the ears is not clear and clean, and it is easy for some insects to crawl into the ears, because the dirt in the ears causes ear infections to be very serious, and you need to go to the doctor immediately, and the ears may not be able to hear after not seeking medical treatment.

Do not soak the ear in water for more than three minutes, the ear will be inflamed if soaked in water for a long time, the ear will be particularly painful after the inflammation, it is easy to not hear, if the ear is not heard due to acquired reasons, it is a pity, but now the technology can make many patients who cannot hear wear a cochlear implant, so that they can hear.

Try to protect your ears and don't let your ears hear loud sounds, which may burst your eardrum and cause you to be unable to hear. I think the ears are the most sensitive of the sensory system, and when you encounter a particularly noisy situation, you should cover your ears to reduce the amount of sound entering your ears. It is recommended not to wear headphones for a long time, and if you wear headphones for a long time, your ears will not be able to stand it.

The ear allows us to hear the beautiful sounds of this world. If you can't hear with your ears, you can only see and smell the world, then how boring and boring the world will be, and when the weather is very cold, you should wear earmuffs to avoid frostbite on your ears. If your ears are frostbitten, your ears will not flow well, and your ears will be damaged easily.

I hope everyone can protect their ears, the ears are the window to understand the world, only listening, seeing, smelling can better understand the world.

Yes, the ears can feel the change in the position of the head, so that balance can be perceived. We should not pick our ears often, wear headphones for a long time, do not go to some places with very loud noise, and seek medical attention immediately if there are some problems, so as to better protect our ears.

Yes, if your ears are uncomfortable, you should go to the hospital immediately for examination, and at the same time, we must learn to prevent noise, stay away from noise, and don't often wear headphones to listen to songs, which can protect our ears.

Yes, because the ears help the body maintain balance. First of all, don't wear headphones for long periods of time, avoid noise, and regularly clean up dirt from your ears.

Yes, try not to wear headphones for a long time, control the volume, don't let your ears be affected by noise, and pluck your ears regularly.
