THYROARYTENOID LIGAMENTS Meaning and
Definition
-
The thyroarytenoid ligaments are tough bands of connective tissue that play a crucial role in the functioning of the vocal cords in the human body. Located within the larynx, these ligaments are positioned between the thyroid cartilage and the arytenoid cartilages, which are structures responsible for regulating the tension and position of the vocal cords during speech and voice production.
These ligaments serve as attachments between the medial surface of the thyroids cartilage's vocal process and the corresponding vocal process of the arytenoid cartilages. This anatomical arrangement contributes to the stability, support, and mobility of the vocal cords.
Functionally, the thyroarytenoid ligaments are essential for controlling the tension and length of the vocal cords. When these ligaments relax, the vocal cords become longer and thinner, resulting in lower-pitched sounds. On the other hand, when the thyroarytenoid ligaments contract, the vocal cords become shorter and thicker, leading to higher-pitched sounds. This process is crucial for phonation, which is the production of vocal sounds and speech.
In summary, the thyroarytenoid ligaments are connective tissue bands that link the thyroid and arytenoid cartilages in the larynx. Their role in controlling the tension and mobility of the vocal cords is key to the production of sounds and speech in the human voice.

Etymology of THYROARYTENOID LIGAMENTS
The term "thyroarytenoid ligaments" is derived from two main components: "thyroarytenoid" and "ligaments".
1. Thyroarytenoid:
- "Thyro-" is derived from the Greek word "thyreos" meaning "shield" or "thyroid gland". It refers to the thyroid cartilage, which is a shield-shaped structure in the throat area.
- "-arytenoid" is derived from the Greek word "arytenoeidēs" meaning "like the ladle". It refers to the arytenoid cartilages, which are paired cartilages in the larynx that control vocal fold movement and voice production.
2. Ligaments:
- "Ligament" comes from the Latin word "ligamentum", meaning "bond" or "tie".
