The vocal cords (also called vocal folds) are 2 bands of smooth muscle tissue found in the voice box (larynx). The larynx is set in the neck at the top of the windpipe (trachea). The vocal cords vibrate and air passes through the cords from the lungs to make the sound of your voice.
Is vocal cord a tissue?
Vocal cord disorders are any anatomical or functional issue that affects the vocal cords. The vocal cords (also called vocal folds) are two bands of smooth muscle tissue found in the larynx (voice box). The vocal cords vibrate and air passes through the cords from the lungs to produce the sound of your voice.

What muscle forms vocal cords?
Vocal folds (true vocal cords) The vocal folds also contain muscle fibers originating from the vocalis part of the thyroarytenoid muscle, which lies deep and inferior, parallel with the vocal ligament to which it is attached at the posterior end.
What type of tissue are vocal cords?
The vocal folds are a pair of rubber band-like tissues located in your larynx (voice box) directly above the windpipe (trachea). They’re made of up several layers of cells, including muscle and an elastic layer, known as the mucosa.
Can you talk without vocal cords?
Without your vocal cords and with a stoma, you are not able to speak in the normal way. This can be very difficult to cope with. But there are now several ways to help you make sounds and learn to speak again.
Why are vocal cords white?
Dysplasia (pre-cancer) of the vocal cords can result in hoarseness and often presents as white patches (leukoplakia) or red patches (erythroplasia) on one or both vocal cords.
What is the function of vocal cords?
Briefly, the vocal folds are folds of tissue located in the larynx (voicebox) that have three important functions: To protect the airway from choking on material in the throat. To regulate the flow of air into our lungs. The production of sounds used for speech.
What are vocal cords 8?
What are vocal cords? The cords which are stretched across the voice box or larynx are called vocal cords. Two vocal cords are there across the voice box in such a way that it leaves a narrow slit between them for the passage of air. When the lungs force air through the slit, the vocal cords vibrate producing sound.
Do vocal cords affect swallowing?
The vocal folds, because of the position in the airway, play a vital role in speech, swallowing, and breathing.
What are the muscles in the throat?
These muscles include the omohyoid, sternohyoid, and sternothyroid muscles (ansa cervicalis), and the thyrohyoid muscle (CN XII).  The longitudinal pharyngeal muscles function to condense and expand the pharynx as well as help elevate the pharynx and larynx during swallowing.
Is vocal cord and larynx same?
Your voice box (larynx) sits in the front of your neck. It holds your vocal cords and is responsible for sound production and swallowing. It’s also the entrance to the windpipe and plays a critical role in your airway.
How many muscles are in the larynx?
There are two types of laryngeal muscles, the external (extrinsic) ones, which move the larynx as a whole, and the internal (intrinsic) ones, which move the vocal folds to shape the glottis.
What are the two muscles that make up the body of the vocal folds?
- Posterior cricoarytenoid – These are the only muscles involved in abduction.
- Lateral cricoarytenoid – These are adductors.
- Thyroarytenoid – These are the muscles that form the body of the vocal folds themselves.
- Cricothyroid – These are the vocal fold lengtheners.
What type of muscle tissue is present in the vocal folds?
Layered structure of the adult vocal fold The body is composed of the thyroarytenoid muscle. This layered structure of tissues is very important for vibration of the true vocal folds.
Which epithelium is present in vocal cords?
The lower pair of folds constitutes the true vocal cords, each covered by stratified squamous epithelium. Among the basal cells of this epithelium, Langerhans cells (LCs) form a network of immune competent cells. The stratified squamous epithelium (Fig.
