The vocal fold comprises five layers (deep to superficial layers as follows): thyroarytenoid muscle, deep lamina propria, intermediate lamina propria, superficial lamina propria, and the squamous epithelium.
In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string.
There are two folds, one on either side of the laryngeal cavity. Each fold is comprised of a vocal ligament, a vocalis muscle and a covering mucous membrane. Vibration of these folds in response to air traveling through the larynx allows us to speak, sing, and produce other vocal sounds.
What are vocal cords (vocal folds)? Your vocal cords are two bands of muscle inside your voice box (larynx) that allow you to vocalize, or make sounds. Your voice box sits atop your windpipe (trachea), the tube that allows air to flow to and from your lungs .
The vocal folds (true vocal cords) are the more important of the two sets. Under the control of the muscles of phonation, they are abducted, adducted, relaxed and tensed to control the pitch of the sound created.
Anatomy of the Vocal Cords. Vocal cords are also referred to as vocal folds, or vocal bands, or even, in some ways most appropriately, “laryngeal lips.” These lips take the shape of a “V” pointing straight anteriorly and the legs of the “V” proceeding horizontally in a posterior direction.
Key Components of the Voice Box. Cartilages. Muscles. Nerves. Vocal Folds. Voice Box Cartilages. There are three cartilages within the larynx. Thyroid Cartilage. Forms the front portion of the larynx. Most forward part comprises the “Adam’s apple” Houses the vocal folds. Vocal folds attach just below the Adam’s apple. Cricoid Cartilage.
Vocal Folds (Vocal Cords)-These remarkable structures provide a valve for the airway and also vibrate to produce the voice. The vocal folds are multilayered structures, consisting of a muscle covered by a mucosal covering.
During phonation, the vocal folds are brought together by muscles attached to the arytenoids (cartilages structure). As air is forced through the vocal folds, they vibrate and produce sound. By tightening or relaxing the laryngeal muscles, the sounds of your voice can be changed.
The vocal folds (also known as vocal cords) are two pairs of flexible bands of tissue in the larynx that vibrate to produce sound. Each fold extends from the back of the thyroid cartilage to the front of the arytenoid cartilage.
