Asymmetrical Vocal Cord Movement

There is a group of people whose vocal cords both move through a full range of motion, but they do not move in tandem. Think, by analogy, of a person whose eyelids both open and close fully, but just not

Normal Larynx

Below are images of a normal larynx, offered as a point of comparison for all of the examples of laryngeal diseases and disorders elsewhere on Laryngopedia. One can reasonably call the vocal cords, “laryngeal lips.” Thinking of a trumpeter’s lips

Supraglottic Phonation

Supraglottic phonation is making voice by means of supraglottic vibration rather than glottic (true vocal cord) vibration. The supraglottic tissues used for vibration can vary between individuals. Vibrating tissue can be the false vocal cords (false cord phonation), aryepiglottic cords,

Anatomy & Physiology

False Cord Phonation

False cord phonation is making voice by vibrating the false vocal cords. This kind of phonation is unlike normal phonation or voice-making, which uses the true vocal cords. This produces a much deeper, rougher voice quality than normal phonation. It

Anatomy & Physiology

Laryngeal Vestibule

The “airspace” above the level of the vocal folds that is bounded by the posterior surface of the epiglottis, the medial surfaces of the aryepiglottic folds, and the anterior faces of the arytenoid cartilages. Tags

Tracheoesophageal Party Wall

The membranous shared wall between the trachea and esophagus. The tracheoesophageal party wall is also known as the membranous trachea. This membranous wall makes up one-third of the trachea’s circumference; the other two-thirds is bolstered and stiffened by cartilaginous rings.

Anatomy & Physiology

Posterior Commissure

The flat, front-facing surface of the glottic aperture that lies between the vocal cord posterior ends. When the vocal cords are in abducted (breathing) position, the posterior commissure is at its widest, since the cords’ posterior ends are spread furthest apart

Anatomy & Physiology

Anterior Commissure

The point at which the vocal cords are joined together, which is at the most anterior end of each cord. Compare this with the posterior commissure. See also: Anterior Commissure Microweb Tags
