throat
A cartilage member located at the top of the neck (top neck) from the bottom of the mandibular bone.
The man’s throat is more prominent in the neck than the lady’s throat
The larynx is a key organ in the respiratory system and acts as a safety valve to prevent the leakage of food or drink during swallowing to the respiratory canal. In addition, it is a basic organ in the speech system where the vocal cords are constricted as air passes through the lungs during exhalation.
Anatomical description of the throat: The throat consists of several individual cartilages, namely:
The cartilage of the thyroid, and cartilage of the ring, and three cartilage pairs are: cartilage cornea, cartilage of the esophagus, cartilage and Artinoid. These cartilage connect several ligaments (lining the inside of mucous membrane) and muscles, and work on the approximation or dimensions of vocal cords during inhalation or exhalation, Swallowing or speech. There is also at the entrance to the throat cartilage covered with mucous membrane called the tongue of the pomegranate moves to close the throat during swallowing food and on the inner surface of the throat there are protrusions on each side called the upper brosan with two false vocal cords and called the lower brosan with real vocal cords These vocal cords control the tone of the sound by stretching and relaxing, and this is done by small muscles attached to the larynx.
Functions of the larynx
Is an important and vital member for breathing and swallowing, as it acts as a safety valve to prevent the entry of food and drink to the lungs during swallowing, as well as prevent the entry of any foreign objects. This is the only function of the larynx in some animals, but it acquires other qualities to carry out additional important functions in humans and animals. The ability to speak is based primarily on sound output through the proper functioning of the vocal cords.
In total, laryngeal functions can be determined in the following:
Breathing, swallowing, speech, coughing and expulsion of phlegm from the lungs.
In order to get rid of secretions and accumulated mucus, constriction occurs in the muscles of the chest and abdomen, leading to high air pressure inside the chest cavity. As vocal cords move away from each other, the air swells with mucus out of the body.
the sound :
The voice performs several functions: it is a means of communication and understanding, indicating the psychological state of the caller, may indicate the health status of the caller, whether the general situation or the state of the respiratory system
The sound is released from the larynx through the movement of vocal cords, contraction and expansion in a chain manner. The man gets deep inspiration and the vocal cords converge and touch, and then the muscles of the chest and abdomen contract. The air comes out of the sound cords and the pulse of the sound produces.
In terms of sound strength, the energy (the amount of air stored in the lungs) must be available with the safety of the sound cords and the lining of the lining, as well as the smooth convergence between the sound cords.
As speech continues and the energy reaches it, the sound subsides. In order to be able to continue to speak in the same breath, we compensate for this dwindling by the violent movement of the vocal cords.
In order to regain the ability to speak we must stop to be able to take inspiration. As for the sound and purity of sound, this requires touching the cords sound smoothly with the movement of the chain and the integrity of the mucosa. In the sense that any defect in this leads to a change in the tone of sound and the appearance of bronchial sound. It is usually accompanied by weakness of sound, but sometimes show each of them individually, and in some stages of larynx diseases.
