cal fold can be divided into three major layers: the mucosa, the vocal ligament, and the underlying muscle. The mucosa of the vocal fold is highly specialized for its vibratory function; it can also be divided into layers. The most superficial layer is the squamous epithelium. Deep to the epithelium are three

The larynx is located at the point where the respiratory and digestive tracts separate. The entrance to the larynx, or laryngeal inlet, is in the anterior wall of the laryngopharynx. Internally, the wall of the larynx is modified to form the vocal cords.
One key to understanding the vocal fold anatomy is to focus on vocal fold histology. The covering of the free edge of the vocal fold is especially adapted for phonatory vibration. This vocal fold epithelium is squamous rather than respiratory and contains no mucous glands [1].
Laryngeal cavity: •Extends from laryngeal inlet to the trachea. • It is partially divided into three areas by two folds of mucosa. •The upper folds: vestibular folds and the lower folds: the vocal folds. 1- The vestibule lies between inlet and vestibular folds. 2- The laryngeal ventricle (sinus) is the depression between the vestibular ...
The cavity of the larynx is divided into two pairs of two-by-two folds of mucous membrane stretching from front to back with an opening in the midline (Fig. 19-3). The upper pair of folds, called the vestibular folds, has a protective function. The lower pair of folds has cordlike margins; they are termed the
