The term "glottis vera" refers to the narrow, central opening or space found within the larynx, specifically the area between the vocal cords. It is a vital component of the respiratory and phonation systems in humans and most vertebrates. The glottis vera is located between the arytenoid cartilages at the rear and the thyroid cartilage at the front of the larynx.
Within the glottis vera, there are two prominent, fold-like structures known as the vocal cords or vocal folds. These delicate, elastic tissues are responsible for the production of sound during speech and singing. The gap or space separating the vocal cords is known as the rima glottidis. When the vocal cords are relaxed, the glottis vera is open, allowing for the passage of air during normal inhalation and exhalation.
However, during voice production, the glottis vera undergoes changes. The vocal cords can be tensed, stretched, or pressed together, resulting in various phonation characteristics such as pitch, volume, and timbre. By adjusting the size and shape of the glottis vera, individuals can manipulate the flow of air passing through the larynx, allowing them to produce different vocal sounds and control their voice quality.
Understanding the glottis vera is crucial in fields like speech pathology, singing, and vocal training, as it plays a pivotal role in the sound production process.
