Laryngeal ventricle
Laryngeal Ventricle
The Laryngeal Ventricle (pronunciation: la-RIN-jee-al VEN-tri-kul), also known as the ventricle of the larynx or Morgagni's sinus, is a structure found in the larynx that plays a crucial role in voice production.
Etymology
The term "Laryngeal Ventricle" is derived from the Latin words 'larynx' meaning 'throat', and 'ventriculus' meaning 'small cavity'. The term 'Morgagni's sinus' is named after the Italian anatomist Giovanni Battista Morgagni, who first described this structure.
Anatomy
The Laryngeal Ventricle is a midline, sagittal, mucosa-lined space in the larynx, situated between the true vocal cords and the false vocal cords. It extends from the anterior commissure to the arytenoid cartilages.
Function
The Laryngeal Ventricle contributes to the complex process of voice production. It aids in the lubrication of the vocal cords by secreting mucus, which helps in the smooth vibration of the vocal cords during phonation.
