Cricoarytenoid ligament
Cricoarytenoid Ligament
The Cricoarytenoid Ligament is a significant anatomical structure in the human body, specifically within the larynx. It plays a crucial role in the functioning of the vocal cords and is involved in the production of speech and respiration.
Etymology[edit | edit source]
The term "Cricoarytenoid" is derived from the Greek words "krikos" meaning ring and "arytaina" meaning ladle. The ligament is named for its location and shape, as it connects the cricoid cartilage (ring-shaped) and the arytenoid cartilage (ladle-shaped).
Anatomy[edit | edit source]
The Cricoarytenoid Ligament is located in the larynx, which is part of the respiratory system. It connects the cricoid cartilage to the arytenoid cartilage. The ligament is divided into two parts: the anterior cricoarytenoid ligament and the posterior cricoarytenoid ligament.
Anterior Cricoarytenoid Ligament[edit | edit source]
The anterior cricoarytenoid ligament extends from the anterior surface of the arytenoid cartilage to the inner surface of the anterior arch of the cricoid cartilage.
Posterior Cricoarytenoid Ligament[edit | edit source]
The posterior cricoarytenoid ligament extends from the posterior surface of the arytenoid cartilage to the inner surface of the lamina of the cricoid cartilage.
Function[edit | edit source]
The Cricoarytenoid Ligament plays a vital role in the movement of the vocal cords. It allows the arytenoid cartilages to rotate and slide, which in turn enables the vocal cords to open and close. This movement is essential for the production of speech and the control of airflow during respiration.
