Definition

1. Noun:
   • Either of the upper two vocal cords that are not involved in vocalization: The "false vocal cord" refers to a pair of folds of mucous membrane located above the true vocal cords in the larynx. They do not typically vibrate to produce sound for speech but play a role in other functions.

Usage

• The term "false vocal cord" is used in anatomy, physiology, and medicine to describe specific structures in the larynx. It is a technical term.
• It is often used in contrast to the "true vocal cords" (or vocal folds), which are the primary sound-producing structures.

Examples

• Noun:
  • During the examination, the doctor noted inflammation in the patient's false vocal cord.
  • The false vocal cord, or vestibular fold, helps protect the airway during swallowing.

Advanced Usage

• Anatomical Context: In detailed anatomical descriptions, the "false vocal cord" is also known as the "vestibular fold" or "ventricular fold." It forms the lower boundary of the laryngeal ventricle.
  • The study focused on the mucosal wave pattern of the false vocal cord.
• Functional Role: While not for phonation, the false vocal cords can be involved in certain types of vocalization, such as deep growling or throat singing techniques, and in airway protection.
  • Some vocalists learn to engage the false vocal cords to produce distortion effects.

Variants and Related Words

• Vestibular fold (n): A synonym for "false vocal cord," emphasizing its location in the vestibule of the larynx.
• Ventricular fold (n): Another synonym, referring to its position bordering the laryngeal ventricle.
• True vocal cord (n): The primary pair of folds used for sound production, located inferior to the false vocal cords. Also called the "vocal fold."

Synonyms

• Vestibular fold
• Ventricular fold
• (Less common) Superior vocal cord

Notes

• The "false vocal cord" is a fixed anatomical structure. There are no phrasal verbs or idioms associated with this specific technical term.
• It is important to distinguish this term from the "true vocal cords," as they have different functions.
