In females during puberty, the vocal muscle thickens slightly, but remains very supple and narrow. The squamous mucosa also differentiates into three distinct layers (the lamina propria) on the free edge of the vocal folds. The sub- and supraglottic glandular mucosa becomes hormone-dependent to estrogens and progesterone.
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.
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 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."
Ligament vocal fold cysts- located within the deeper layers of the lamina propria or on the vocal ligament. [1] The symptoms of vocal fold cysts vary but most commonly include a hoarse voice and problems with the pitch of the voice. Vocal fold cysts are diagnosed based on gathering a case history, perceptual examination, and laryngeal imaging. [3]
The free inferior border forms the vestibular ligament [2] (which together with the overlying mucosa constitutes the vestibular fold). The lower fibres of the quadrangular ligament condense to form the false vocal cords or the vestibular fold, while the upper fibres of the cricovocal ligaments condense to form the true vocal cord.
The dense layer is the deeper layer of the lamina propria. It consists of dense connective tissue with a large amount of fibers. Between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for the all layers of the mucosa and sends capillaries into the connective tissue papillae.

The vestibular fold (ventricular fold, superior or false vocal cord) is one of two thick folds of mucous membrane, each enclosing a narrow band of fibrous tissue, the vestibular ligament, which is attached in front to the angle of the thyroid cartilage immediately below the attachment of the epiglottis, and behind to the antero-lateral surface of the arytenoid cartilage, a short distance above ...
