What causes vibration in throat?

Spasmodic dysphonia, or laryngeal dystonia, is a disorder affecting the voice muscles in the larynx, also called the voice box. When you speak, air from your lungs is pushed between two elastic structures—called vocal folds—causing them to vibrate and produce your voice.

What part of your throat vibrates and contains your vocal cords?

Your larynx is part of your respiratory system. It’s a hollow tube that lets air pass from your throat (pharynx) to your trachea on the way to your lungs. It also contains your vocal cords and is essential to human speech, so it’s often called the voice box.

What causes vocal cords to vibrate?

In order to produce voice, the lungs blow air against vocal folds in the nearly-closed position. Air pushes through the very small space between them and in so doing, makes the covering of the vocal folds, known as the mucosa, vibrate. This occurs by means of a phenomenon known as the venturi effect.

What is an glottis?

(GLAH-tis) The middle part of the larynx; the area where the vocal cords are located. Enlarge.

Why does my throat gurgle when I breathe?

Noisy breathing is typically caused by a partial blockage or narrowing at some point in the airways (respiratory tract). This can occur in the mouth or nose, in the throat, in the larynx (voice box), in the trachea (breathing tube), or further down into the lungs.

What do throat polyps look like?

Polyps can be on one or both of the vocal folds. They may look like a swollen spot or bump, a blister, or a thin, long growth. Most polyps are bigger than nodules. You may hear them called polypoid degeneration or Reinke’s edema.

Which part of the larynx vibrates when air from the lungs pass thru?

The vocal folds (vocal cords) are attached within the larynx to the largest of the laryngeal cartilages known as the thyroid cartilage or “Adam’s apple”. The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs.

What is mucosal wave?

The mucosal wave is the wave-like movement of the vocal fold cover (epithelium and superficial layer of the lamina propria) during vibration.

What is vocal tremor?

Vocal tremor is a neurological disorder that causes involuntary movement of muscles in the throat, larynx (voice box), and vocal cords. The condition usually involves rhythmic muscle movements, which can cause quavering of the voice.

What is laryngeal dystonia?

Laryngeal dystonia (LD) is a chronic voice disorder characterized by spasms of the muscles of the voice box (larynx). These muscles control the voice. The spasms can result in tightness in the throat, recurrent hoarseness, and changes in voice quality and/or difficulty speaking.

What is Apharynx?

(FAYR-inx) The hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). The pharynx is about 5 inches long, depending on body size. Also called throat.
