What is ventricle of morgagni?
The laryngeal ventricle, (also called the ventricle of the larynx, laryngeal sinus, or Morgagni’s sinus) is a fusiform fossa, situated between the vestibular and vocal folds on either side, and extending nearly their entire length.
What is the larynx ventricle?
The laryngeal ventricle is the fossa or sinus that lies between the vocal and vestibular folds on either side. The vocal folds are commonly referred to as the vocal cords and the vestibular folds as the false vocal cords.
What is the true vocal cord?
The true vocal cords are the thickened, free edge of the cricovocal membrane, the cricovocal ligament, lined by mucous membrane 1. Together they form part of the glottis, the V-shaped aperture through which air passes.
What are the false vocal cords?
The false vocal cords (vestibular folds, ventricular folds, ventricular bands) are paired shelf-like structures located within the supraglottic larynx that divide the vestibule above from the ventricle below.
Where is the Vallecula Epiglottica located?
The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis. Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold. The valleculae can collect saliva to prevent initiation of the swallowing reflex.
What is Laryngocele?
Introduction. A laryngocele is an abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, is filled with air, and is in communication with the laryngeal lumen [1, 2].
What is larynx made of?
The larynx is composed of 3 large, unpaired cartilages (cricoid, thyroid, epiglottis); 3 pairs of smaller cartilages (arytenoids, corniculate, cuneiform); and a number of intrinsic muscles (see the image and video below).
What is corniculate cartilage?
The corniculate cartilages are paired, elastic and accessory cartilages of the larynx that lie superior to and articulate with the apices of the arytenoid cartilages. They are components of the laryngeal cartilages.
Do we have 2 vocal cords?
Both sites represent large folds in the mucous membrane lining the larynx. The first pair is known as the false vocal cords, while the second is the true vocal cords (glottis).
Who has shorter vocal cords?
Vocal chords in women are thinner and shorter than in men. It varies in length from 12.5 mm and 17.5 mm. So the vocal cords in women produce sound of high frequency or high pitch. So women have a shriller voice than men.
What is the Thyroarytenoid muscle?
46588. Anatomical terms of muscle. The thyroarytenoid muscle is a broad, thin muscle that forms the body of the vocal fold and that supports the wall of the ventricle and its appendix. It functions to shorten the vocal folds.
What is Corniculate cartilage?
