What is the larynx?
Larynx, also called voice box, is an authority in the shape of a funnel that is located in the throat. It is formed by hyoid bones and nine cartilage, which are connected by muscles and ligaments. The primary features of the larynx are to protect the trachea or trachea, swallowing and sound production. This directs food and fluids on the sides and down the esophagus, a pipe that passes between the upper neck or pharynx and stomach. If this did not happen, whatever was absorbed, it would go on the wind and the lungs. Epiglottis raises between swallows, allowing air to flow freely. When you make sounds, the arrytenoid muscles of the arrytenoid cartilage turn. This cartilage can move to 170 different positions. The Glottis narrows and controls the air flow, causing vibration of vocal cords and creating sound. The sounds created would be too quiet to actually hear without the thickening provided by the chest, pharynx, trachea, larynx, nose and mouth.
voice problems can be caused by a number of disorders in the trachea, but most of them are dismembered and generally respond to treatment. One of the common causes is lesion or abnormal areas of tissue on vocal folds. These are often caused by the use of incorrect speech methods in speaking, shouting or singing. Polyps, or small tissue growth, can quickly form an excessive cough or screaming such as a shout for a ball game. When the gland does not drain properly, cysts, cysts, liquid filled with bags can occur.
In most cases, these disorders can be treated with rest and voice therapy. In some cases, operations to remove cysty or polyp are required, which will not only respond to therapy. Another common complaint is a hoarse or loss of voice caused by laryngitis or larynxitis. There are many causes of laryngitis such as smoke, harmful vapors and bacterial or viral infections. Treatment will depend on the basic cause.
In some cases, neck cancer maydevelop in the larynx. The most common cause is smoking and heavy drinking. Treatment includes surgical removal of cancer, followed by some type of nuclear drugs. If the tumor is small enough, the surgery is usually sufficient surgery followed by radiation therapy. If cancer spreads to lymph nodes, treatment will generally require a combination of radiation and chemotherapy. If the tumor is placed in such a way that part or all vocal cords need to be removed, artificial implants are available. Voice therapy is generally designed as part of the recovery process.
Thesymptoms of neck cancer include hitsanger, cough and bloody mucus without any apparent cause. Sometimes lumps appear or voice quality may change. If these symptoms continue for more than two weeks, it is important to check them by a doctor. If it is caught early, cancer in the larynx can be successfully treated.
