Vocal fold

The vocal folds, also known as vocal cords, are a pair of soft tissues that are found in the larynx (voice box). They are essential for human speech and phonation.

Anatomy[edit | edit source]

The vocal folds are located within the larynx at the base of the trachea. They are attached at the front (anterior) to the thyroid cartilage (Adam's apple), and at the back (posterior) to the arytenoid cartilages. The space between the two vocal folds is known as the glottis.

Function[edit | edit source]

The primary function of the vocal folds is to produce sound for speech. This is achieved by the process of phonation, where the vocal folds vibrate to modulate the flow of air being expelled from the lungs during respiration. The pitch and volume of the sound produced can be controlled by altering the tension and length of the vocal folds.

Disorders[edit | edit source]

There are several disorders that can affect the vocal folds, including:

  • Vocal fold nodules and polyps: These are benign growths that can cause a hoarse voice and other vocal problems.
  • Vocal fold paralysis: This is a condition where one or both of the vocal folds cannot move. It can cause difficulties with speech and breathing.
  • Laryngitis: This is inflammation of the larynx, often caused by a viral infection, that can cause hoarseness and loss of voice.

Treatment[edit | edit source]

Treatment for disorders of the vocal folds depends on the specific condition and its severity. It may include voice therapy, medication, or surgery.
