Vestibular fold

Ventricular bands ( plicae vestibular ), and vestibular folds, atrial folds, false vocal cords or false vocal folds called, are located in the larynx just above the "true" vocal cords. There are projecting horizontally superposed folds couple sitting on the vocal folds.

They are used to hold my breath to clear his throat and are increasingly being used as an imaging effect organ at growling; usually in collaboration with the right vocal fold. They are also used in the so-called Kargyraa in the Central Asian throat-singing.

The term of the vestibular folds voice as an expression of hyperkinetic dysphonia refers to a change in articulation of the human voice by the extreme compression of the vestibular folds. The symptoms are a strong hoarse voice squeezed.

In dogs, horses and pigs, the pocket tape forms the front boundary of the access to the larynx bag. Above the vocal folds ( plicae vocales ) larger protuberances are possible for some mammals, they are Ventriculus Morgagnii or also called laryngeal ventricle. In humans, there is the laryngocele as pathological protuberance.

In particular, in the odd-toed ungulates, they can assume greater proportions. After cranial these protuberances by the ventricular bands, limited ( plicae vestibular ). These sacs act as resonators. In addition, several species of monkeys, as the howler monkeys and the orang -utans, these sacs, ulcer Morgagnii have evolves as so-called throat pouches.
