What are the structural characteristics of the ear, what is the structure of the ear?

The main structure of the ear can be divided into three main parts: the outer ear, the middle ear, and the inner ear.

Outer ear: The outer ear includes the pinna and the external auditory canal, which we usually talk about"Ears"In fact, it is only the part of the auricle, which has the effect of collecting sound. The external auditory canal is a channel for sound transmission, which is about long, hollow and curved inside, and the 1 3 of the auricle is composed of cartilage, and the inner 2 3 is composed of bone, and the surface is covered by **.

Middle ear: The middle ear consists of the tympanic chamber, tympanic sinus, mastoid process, and eustachian tube.

The eardrum is the eardrum that separates the outer ear from the middle ear and the outer wall of the tympanic chamber. The tympanic chamber is a cavity that contains the smallest bone in the human body, the ossicles. The three ossicles of the malleus, incus, and stapes, combine to form the ossicular chain, which connects to the eardrum at one end and the auditory tissue of the inner ear at the other.

As sound waves travel through the ear canal, the eardrum vibrates the eardrum, which then transmits the vibrations to the inner ear through the ossicular chain.

The tympanic sinus is a cavity located above the back of the tympanic cavity, and its anatomical position is very peculiar: it is adjacent to the tympanic cavity in front and mastoids in the posterior and inferior posteriorly, and there are many important sites around it, so it is often used here for otological surgeries.

The mastoid process is located behind the ear, and the protrusion behind the earlobe is its apex. The mastoid process is separated by thin bony plates in a honeycomb shape, called the mastoid air chamber, which protects the inner ear from the effects of external climate change.

The Eustachian tube connects the nasopharynx to the middle ear, and it regulates the balance between the middle ear and the outside air pressure, so that the middle ear is consistent with the air pressure of the external environment.

Inner ear: The inner ear has a complex structure, so it is also called"Get lost", consisting of the cochlea in the anterior, the vestibule in the middle, and the semicircular canal in the posterior.

The vibration of sound waves is transmitted to the inner ear, and the vibration of the eardrum can be transmitted through the ossicular chain to become the vibration of the vestibular window, causing the movement of the cochlear lymph fluid in the inner ear, so that the auditory hair cells are excited and the auditory sense is formed. The cochlea is responsible for processing sound signals.

The structure of the ear, what is the structure of the ear?

The ear consists of three parts: the outer ear, the middle ear, and the inner ear. Auditory receptors and positional receptors are located in the inner ear, so the ear is also called a auditory. The outer and middle ears are also listed as appendages to hearing bits.

The outer ear consists of two parts: the auricular and the external auditory canal. In addition, there are ear hairs and some glands on the ** of the external auditory canal, and the secretions and ear hairs of the glands have a certain blocking effect on the entry of foreign bodies such as dust from the outside.

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.

The structure of the ear, what is the structure of the ear?

The ear, mainly bai, includes the outer ear.

There are three parts of the middle ear and the inner ear, and the outer ear includes two parts, the pinna and the external auditory canal, the outer ear canal is connected to the tympanic membrane, and the tympanic membrane is the tympanic chamber, and the inner ear mainly includes the vestibule, semicircular canal and cochlea three parts, we generally pick the ear in the external auditory canal, if you dig too deep will hurt the eardrum, so try not to go too deep into the ear.

The human ear has two important functions, one is the well-known auditory function, which involves the auditory system, which is divided into three parts: the outer ear, the middle ear, and the inner ear; Other.

One is the balancing function, which has to do with the antechamber system. The balance of the human body is mainly accomplished by the visual, proprioceptive, and vestibular systems. With the exception of the outer ear, the rest of the human body is inside the skull.
