How Do You Spell LIGAMENTUM CRICOARYTAENOIDEUM POSTERIUS?

1. The ligamentum cricoarytaenoideum posterius, also known as the posterior cricoarytenoid ligament, is a term from anatomy that refers to a specific ligament located in the larynx, or voice box.

   The larynx is an essential structure found in the throat, responsible for various functions including voice production and protecting the airways during swallowing. It is composed of several cartilages and ligaments that work together to facilitate these functions.

   The ligamentum cricoarytaenoideum posterius is a robust band of connective tissue that connects the cricoid cartilage to the arytenoid cartilage posteriorly, hence its name. The cricoid cartilage is shaped like a ring and sits just below the thyroid cartilage, which houses the vocal folds. The arytenoid cartilages are paired, pyramid-shaped structures that sit on top of the cricoid cartilage.

   The primary function of the ligamentum cricoarytaenoideum posterius is to control the movements of the arytenoid cartilages. These movements are crucial for the proper functioning of the vocal folds during voice production. When the ligament contracts, it causes the arytenoid cartilages to rotate outwards, which stretches and tenses the vocal folds. This action allows for the vocal folds to vibrate and produce sound when air passes through them.

   In summary, the ligamentum cricoarytaenoideum posterius is an important structure in the larynx that enables the precise control of vocal fold movements, contributing to the production of sound and speech.

2. Posterior cricoarytenoid ligament, a strong elastic band, reinforcing posteriorly the capsule of the cricoarytenoid articulation, passing between the external surface of the arytenoid cartilage to the upper margin of the lamina of the cricoid.
