Definition

Noun (Anatomy): 1. A fold of mucous membrane in the larynx, located above and parallel to the true vocal folds (vocal cords). These folds are not primarily used for sound production (phonation) but play a role in protecting the airway and can be involved in certain types of vocalization, such as ventricular voice or growling.

Usage

The term "ventricular fold" is a specific anatomical term. It is used in medical, biological, and vocal pedagogy contexts to describe a precise structure within the larynx (voice box).

Examples

• Noun:
  • During the laryngoscopy, the doctor observed that the ventricular folds were slightly inflamed.
  • The ventricular fold lies superior to the true vocal fold and is also known as the false vocal cord.
  • Some singers learn to engage their ventricular folds to produce a distorted rock vocal effect.

Advanced Usage

• "Ventricular phonation": A mode of voice production where the ventricular folds vibrate instead of, or together with, the true vocal folds, often resulting in a low, rough, or pressed sound quality.
