Human vocal cords are paired structures located in the larynx, just above the trachea, which vibrate and are brought in contact during phonation. The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers.
A labeled anatomical diagram of the vocal folds or cords. Adult men and women typically have different sizes of vocal fold; reflecting the male–female differences in larynx size. Adult male voices are usually lower-pitched and have larger folds.
The lower pair of folds are known as the vocal cords, which produce sounds needed for speech and other vocalizations. The slit-like space between the left and right vocal cords, called the rima glottidis, is the narrowest part of the larynx. The vocal cords and the rima glottidis are together designated as the glottis.
The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx in birds) is filtered. In birds , it consists of the trachea , the syrinx , the oral cavity, the upper part of the esophagus , and the beak .
The movement of gas through the larynx, pharynx and mouth allows humans to speak, or phonate. Vocalization, or singing, in birds occurs via the syrinx, an organ located at the base of the trachea. The vibration of air flowing across the larynx (vocal cords), in humans, and the syrinx, in birds
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
If the vocal cords are completely relaxed, with the arytenoid cartilages apart for maximum airflow, the cords do not vibrate. This is voiceless phonation, and is extremely common with obstruents. If the arytenoids are pressed together for glottal closure, the vocal cords block the airstream, producing stop sounds such as the glottal stop.
The larynx, commonly known as the "voice box", is a cartilaginous structure in the trachea responsible for phonation. The vocal folds (chords) are held together so that they vibrate, or held apart so that they do not. The positions of the vocal folds are achieved by movement of the arytenoid cartilages. [48]
