What is the larynx?
The larynx is the connecting piece between the pharynx and the trachea. It consists of four cartilage parts:
- Thyroid cartilage: the anterior, palpable wall; visible in men as the "Adam's apple" on the outside of the neck;
- Cricoid cartilage: lies horizontally under the thyroid cartilage;
- Epiglottis: Connects to the thyroid cartilage and closes the entrance of the larynx to the pharynx - so the food can not enter the trachea during swallowing.
- Arytenoid cartilage: Connected to the cricoid cartilage via a joint;
Inside the larynx, approximately in the middle, are the vocal cords or vocal folds necessary for speech.Acute bronchitis - what you can do yourselfWhat can you do about the painful cough? And how can you prevent it? What can you do about the painful cough? And how can we prevent it?
What function does the larynx have?
The main function of the larynx is in the reflex closure of the respiratory tract. This vital function prevents foreign bodies from entering the lungs. In addition, the larynx inside is lined with a mucous membrane, which has a ciliated epithelium. Continuous movement of the cilia causes airborne particles to be carried back up so they can be coughed off.
Fine further function of the larynx consists in the adjustable voice formation on the vocal cords, which are stretched between the Stell- and the circular cartilage. When inhaled, they are open and without tension, while exhaling they are stretched and made to vibrate by the passing air stream. The stronger the tension, the higher the tones are produced.
