Vocal cord structure:

Structure of vocal cords vocal cords are the main structure of human voice, ranging from slight hoarseness to complete loss of voice, which is mostly caused by vocal cord lesions or other reasons that hinder the normal movement of vocal cords. The vocal cords are located below the false vocal cords (ventricles) in the laryngeal cavity, one on the left and one on the right. They are composed of auditory ligaments, muscles and mucous membranes. They begin at the inner surface of the intersection of thyroid cartilage plates and end at the vocal cord process at the front end of the bottom of spoon cartilage. When the vocal cords are opened, there is an isosceles triangle crack, called glottis fissure, through which air enters and exits, which is also the narrowest part of the throat. The vocal cords of adult males in China are generally 18mm~24mm, with an average length of about 20mm, and those of adult females are generally 14mm~ 18mm, with an average length of about15 mm. When the air exhaled from the lungs rushes to the vocal cords that are close together and causes vibration, it makes a sound. The sound emitted by the throat is pitch, which is enhanced and changed by the * * * sound of pharynx, mouth, nose, sinus, trachea and lung (hereinafter referred to as * * * sound cavity) and becomes the heard sound.

In order to protect the vocal cords, it is recommended to pay attention to the following points:

(1) Strengthen physical exercise, enhance physical fitness and improve resistance to upper respiratory tract infection;

(2) Eat less irritating food, avoid excessive use of sound and ban alcohol;

(3) Strengthen labor protection and properly handle harmful gases and dust in the production process;

(4) Teachers and literary and art workers should pay attention to correct vocalization methods, especially during colds, and should not make excessive vocalization;

5] Early hoarseness patients should emphasize vocal cord rest and active treatment at the same time. Protect vocal cords, starting with correct vocalization.

Chronic laryngitis, such as vocal nodules, will make vocal cords and sounds pathological. Even if it gets better after surgery or other treatment, if the vocal habit is not corrected correctly, the lesion may still occur again. Therefore, for voice patients, besides physical and surgical treatment, more attention should be paid to correct voice training.

1. Don't use your voice too much. Excessive use of sound refers to the abuse of sound beyond one's ability. Everyone's vocal ability has three aspects: pitch (sound frequency range), sound intensity (vocal cord tension) and vocal time (pronunciation time). If it exceeds this range, vocal cord lesions will occur. Speak at an appropriate volume and tone, preferably at a constant speed. Don't use the voice too long, too high and too tired.

2. Scientific pronunciation. High, low and tenor are used alternately, because the tenor uses 1/3 in front of the vocal cords, the alto uses 1/3 in the vocal cords and the bass uses 1/3. This pronunciation is not only vivid, but also allows the vocal cords to rest alternately.

3. Get rid of the habit of clearing your throat. Many people may often use this action to cough up phlegm in their throats, or to make their voices clearer. However, this action makes the vocal cords tense in an instant, which is easy to cause vocal cord damage.

4. Treat acute pharyngitis as soon as possible to avoid turning into chronic pharyngitis. Pay attention to voice rest when catching a cold, especially after hoarseness. Treat and avoid cough in time to prevent cough from damaging vocal cords. It is particularly important to avoid shouting or talking for a long time after drinking, catching a cold or getting sore throat, so as not to form vocal nodules.

Besides. Usually eat less irritating food; Quit smoking and drinking; Pay attention to exercise and enhance physical fitness. Children should not often shout loudly, lest vocal cords form shouting nodules.

Small magic formula for protecting sound:
