Home > Larynx

The larynx rests in a frame of cartilage bound by ligaments and muscle. At the front is the thyroid cartilage creating the prominence of the Adam's apple in humans. Below the thyroid cartilage is a ring-shaped cartilage called the cricoid which forms the connection to the traches. Above the larynx is a supporting bone called the hyoid, which moves the larynx during swallowing. The epiglottis is another cartilage that extents upwards behind the back of the tongueAlternative meaning: Tongue, Highland The Tongue is the large bundle of muscles on the floor of the mouth that manipulates food for chewing and swallowing. is one of the organs of taste. Much of the surface of the tongue is covered in taste buds. assists and projects down through the hyoid bone.

Within the larynx there is the supraglottis at the top, consisting of the epiglottis, the aryepiglottic folds, the false vocal cords and the ventricleIn anatomy, a ventricle is a part of the body filled with fluid. For the pumping chambers of the heart, see Ventricle (heart). For the ventricles of the brain, see ventricular system.. In the middle is the glottisThe space between the vocal cords is called the glottis . As the vocal cords vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing . Sounds production involving only the glottis is called glottal''. English h, within which are the two true vocal folds (also called vocal cords), thin muscular strips coated in mucosa. One end of the folds is joined to the thyroid cartilage at the anterior commissure, the other end of each fold is joined to the arytenoid cartilage which move within the posterior cricoid, muscles attached to the arytenoid pull the folds apart during breathing and brings them close together during sound production. The lowest portion of the larynx is the subglottis.

During swallowing the larynx (and the epiglottis) close to prevent swallowed material entering the lungThe lung is an organ belonging to the respiratory system and interfacing to the circulatory system of air-breathing vertebrates. Its function is to exchange oxygen from air with carbon dioxide from blood. The process in which this happens is called " extes, there is also a strong coughCough is also the name of a band, see Cough (band A cough is a sudden, often repetitive, spasmodic contraction of the thoracic cavity, resulting in violent release of air from the lungs, and usually accompanied by a distinctive sound. A cough is usually i reflex to protect the lungs. Sensation is transferred by the superior laryngeal nerve (glottis and supraglottis) and the recurrent laryngeal nerve (subglottis and muscles), both branches of the vagus nerve.

Sound pitch and volume are created in the larynx, while articulation of the sound derives from the use of teeth, tongue, palate, and lips.
