cricoarytenoid การใช้

• The main respiratory muscles are the posterior cricoarytenoid muscles.
• Cytochrome c Oxidase Deficiency in Human Posterior Cricoarytenoid Muscle.
• Paralysis of the vocal fold may also result from mechanical breakdown of the cricoarytenoid joint.
• Notably, the only muscle capable of separating the vocal cords for normal breathing is the posterior cricoarytenoid.
• The posterior cricoarytenoid muscles, the only muscles that can open the vocal cords, are innervated by this nerve.
• Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoid, thyroarytenoid, and interarytenoid muscles.
• A suture is used to emulate the action of the lateral cricoarytenoid muscle and position the paralyzed vocal cord closer to the midline.
• The phonatory muscles are divided into adductors ( lateral cricoarytenoid muscles, arytenoid muscles ) and tensors ( cricothyroid muscles, thyroarytenoid muscles ).
• The posterior cricoarytenoid ( PCA ) is a muscle of the larynx that is responsible for pulling the vocal folds apart from one another.
• Other techniques can involve breathing through a straw and panting, which widens the opening of the throat by activating the Posterior cricoarytenoid ( PCA ) muscle.
• The suture placed in the arytenoid adduction procedure mimics the action of the lateral cricoarytenoid muscle and pulls the vocal process of the arytenoid cartilage medially and inferiorly.
• The "'Cricoarytenoid ligament "'extends from the lamina of the cricoid cartilage to the medial surface of the base and muscular process of the arytenoid cartilage.
• The arytenoids articulate with the supero-lateral parts of the cricoid cartilage lamina, forming the cricoarytenoid joints at which they can move apart, tilt anteriorly or posteriorly, and rotate.
