These fibers run roughly parallel to the vocal fold edge and these two layers of the lamina propria comprise the vocal ligament. The transition layer is primarily structural, giving the vocal fold support as well as providing adhesion between the mucosa, or cover, and the body, the thyroarytenoid muscle.
In the female larynx, the vocal fold cover thickens with aging. The superficial layer of the lamina propria loses density as it becomes more edematous. The intermediate layer of the lamina propria tends to atrophy only in men. The deep layer of the lamina propria of the male vocal fold thickens because of increased collagen deposits.
Superficial lamina propria (Reinke's space) Intermediate lamina propria; Deep lamina propria; Vocalis muscle; In order for humans to produce sound for speech, the vocal folds must readily vibrate. The two layers of the vocal cords that vibrate are the Reinke's space and the overlying epithelium. In fact, these layers move freely over the more ...
The vocal folds consist of 3 primary layers; the Epithelium, the Lamina Propria (containing superficial, intermediate and deep layers) and the Thyroarytenoid Muscle. Vocal fold cysts commonly appear in the Superficial portion of the Lamina Propria, the cyst size impacts the nature of this layer making it more rigid.
The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."
It contains the vestibular folds, and between these and the vocal folds are the laryngeal ventricles. [1] The vestibule is an opening in the lateral wall of the larynx, between the vestibular fold above and the vocal folds below. It is the inlet to another cavity in the lateral wall of larynx, the laryngeal ventricle.

The cricothyroid muscle produces tension and elongation of the vocal cords. [ 3 ] [ 5 ] They draw up the arch of the cricoid cartilage and tilt back the upper border of the cricoid cartilage lamina. [ 3 ] [ 5 ] The distance between the vocal processes and the angle of the thyroid is increased, elongating [ 3 ] and thus tensing the vocal folds ...
