The vocal folds are commonly referred to as vocal cords, and less commonly as vocal flaps or vocal bands. The term vocal cords was coined by the French anatomist Antoine Ferrein in 1741. In his violin analogy of the human voice, he postulated that the moving air acted like a bow on cordes vocales. [43]
Adult male voices are usually lower-pitched and have larger folds. The male vocal folds (which would be measured vertically in the opposite diagram), are between 17 mm and 25 mm in length. [10] The female vocal folds are between 12.5 mm and 17.5 mm in length. The folds are within the larynx.
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 ...
Production of falsetto, on the other hand, vibrates only the ligamentous edges of the vocal folds while leaving each fold's body relatively relaxed. [8] Transition from modal voice to falsetto occurs when each vocal cord's main body, or vocalis muscle, relaxes, enabling the cricothyroid muscles to stretch the vocal ligaments. [6]
Vocal pedagogists may use the term vocal register to refer to any of the following: [2] A labeled anatomical diagram of the vocal folds or cords. a particular part of the vocal range such as the upper, middle, or lower registers; a resonance area such as chest voice or head voice; a phonatory process; a certain vocal timbre
It is created by using only the back of the vocal folds. The lower part of the whistle register may overlap the upper parts of the modal and falsetto registers, making it possible for singers to phonate these notes in different ways. However, fundamentally, the whistle register is most commonly used to produce pitches above D 6. As with the ...
The rima glottidis is the narrowest part of larynx. It is longer (~23 mm) in males than in females (17–18 mm). [1]The rima glottidis is an aperture between the two true vocal cords anteriorly, and the bases and vocal process of the two arytenoid cartilages posteriorly.
It is to the vestibular ligaments (vestibular folds once covered with mucous membrane) what the rima glottidis is to the vocal ligaments (vocal folds once covered with mucous membrane) – the space formed when the folds are separated. It can be defined as the space in between the false vocal cords, and allows air to pass through the larynx.
