External ear: it is composed of auricle and external ear canal. The shape of auricle is responsible for collecting sound waves. The external ear canal can transmit sound waves.

Middle ear: located between the outer ear and the inner ear, it has tympanic membrane, three auditory ossicles, oval window, Eustachian tube, etc. the tympanic membrane separates the outer ear canal and the middle ear,

Its main function is to transmit the three auditory ossicles vibrated by the external sound waves, and the three auditory ossicles are used to convert the sound waves into the liquid waves of the external lymph in the inner ear and cochlea,

The eustachian tube is a tube connecting the middle ear to the throat to balance the pressure inside and outside the eardrum.

Inner ear: including cochlea, vestibule and semicircular canal. Inner ear includes two parts: auditory organ (cochlea) and sensory organ (semicircular canal or vestibular organ).

Why is there earwax?

In fact, it is to add an extra layer of protective film to the ear so that it will not be directly damaged by the outside world.

Earwax is formed in the external auditory canal and secretes “stare wax”, or “stare wax”, from the earwax film. Earwax is an important defense line for the body to protect the inner precise organization of the ear and protect the hearing.

The common people’s earwax is divided into dry and wet sticky two poles. The former is best cleaned, and it will be pushed out continuously, so it will fall off automatically.

It is more difficult to clean the wet and sticky earwax. It is suggested that you should ask a professional otolaryngologist to deal with it so as not to hurt the eardrum and cause sequelae.

Earwax and earwax can prevent dust, microorganisms, insects and foreign water from entering the middle and inner ear chambers,

So as to achieve the protective effect. Whether earwax and earwax are dry or wet is related to genetic inheritance.
