Glottis vera is the medical term used to describe the narrowest part of the larynx. Synonyms for this term include true vocal cords, vocal folds, and vocal ligaments. The glottis vera plays an important role in voice production and respiration. When air is expelled from the lungs, the glottis vera constricts, which causes the vocal cords to vibrate and produce sound. These synonyms make it easier for medical professionals to communicate about the specific structures involved in laryngeal function. Additionally, they provide patients with a better understanding of their anatomy and why certain issues may arise.
