Ventriculus laryngis ("larynx pocket") is a protrusion of the mucous membrane of the interior of the larynx to the side in humans as well as in dogs , horses and pigs, but also some primates, such as the howler monkeys . It is placed between the pocket and vocal cord , which also limit access to the larynx pocket .
Clinical significance
In humans, a bulging of the laryngeal ventricle known as a laryngocele can form.
In clinical jargon, the laryngeal ventriculus is also referred to as the Morgagni ventricle, Morgagni pocket or Ventriculus Morgagni according to Giovanni Battista Morgagni .
In horses with larynx whistles , the vocal folds are tightened surgically by resecting the mucous membrane of the larynx pocket and then suturing the scar.
