30 Οκτ 2023 · There are two folds, one on either side of the laryngeal cavity. Each fold is comprised of a vocal ligament, a vocalis muscle and a covering mucous membrane. Vibration of these folds in response to air traveling through the larynx allows us to speak, sing, and produce other vocal sounds.
5 Σεπ 2024 · Vocal ligament – Lies at the free upper edge of the cricothryoid ligament. Vocalis muscle – Exceptionally fine muscle fibres that lie lateral to the vocal ligaments. The vocal folds are relatively avascular, and appear white in colour. The space between the vocal folds is known as the rima glottidis.
30 Οκτ 2023 · Each mucous membrane-covered vocal fold contains a vocal ligament that extends from the inner surface of the thyroid cartilage to the vocal process of the corresponding arytenoid cartilage. Running parallel to each vocal ligament is the vocalis muscle which is responsible for adjusting the tension of the vocal folds.
7 Αυγ 2023 · Each arytenoid cartilage has two important processes that extend from it. The first being the vocal process responsible for serving as an attachment for the vocal ligament. The second process is the muscular process and serves as an attachment for intrinsic laryngeal muscles.
30 Οκτ 2023 · The thyroarytenoid muscle originates from the angle of thyroid cartilage and adjacent cricothyroid ligament. It inserts into the anterolateral surface of arytenoid cartilage, just as the posterior and lateral cricoarytenoid muscles do. As for function, the muscle shortens and relaxes the vocal cords.
17 Δεκ 2020 · In this tutorial, we're going to talk about the membranes and the ligaments of the larynx. And then we're going to look at how the mucosa folds over the ligaments to form the vocal cords. We’re looking here anteriorly at the larynx. You can see the trachea below and the hyoid bone at the top.
The Vocal Folds (plicœ vocales; inferior or true vocal cords) are concerned in the production of sound, and enclose two strong bands, named the vocal ligaments (ligamenta vocales; inferior thyroarytenoid).
