What does the term "conus elasticus" refer to in vocal anatomy?

The term "conus elasticus" refers specifically to a membrane structure in the larynx that plays an important role in the functioning of the vocal folds. It is a part of the connective tissue framework that provides support and elasticity to the larynx and is located beneath the vocal folds. This membrane extends from the vocal folds down to the trachea, helping to maintain the structure and integrity of the airway while also facilitating sound production during phonation. The conus elasticus plays a crucial role in the biomechanics of vocal fold vibration, influencing pitch and phonatory quality.

Understanding this structure is essential for grasping how vocal fold mechanics work in speech and singing, as it allows for the necessary tension and flexibility required for effective sound production.
