Two fibrous sheets of tissue in the larynx that are responsible for voice production. The vocal cords are attached at the front to the thyroid cartilage and at the rear to the arytenoid cartilages. To produce sound, the vocal cords, which normally form a Vshaped opening, close and vibrate as air expelled from the lungs passes between them. Alterations in cord tension produce sounds of different pitch, which are modified by the tongue, mouth, and lips to form speech. voice-box See larynx.
See LARYNGOSCOPE; LARYNX; VOICE AND SPEECH.
The air carrying the voice produced in the LARYNX passes through the throat, mouth and nose. The shape and size of these structures will in?uence the timbre of the voice, or vocal resonance. This will vary from person to person and even within an individual; for example, with a cold.... vocal resonance
(vocal cords) the two folds of tissue which protrude from the sides of the *larynx to form a narrow slit (glottis) across the air passage (see illustration). Their controlled interference with the expiratory air flow produces audible vibrations that make up speech, song, and all other vocal noises. Alterations in the vocal folds themselves or in their nerve supply by disease interfere with phonation.... vocal folds
