thyroarytenoid การใช้

It runs between the vestibular fold, thyroarytenoid muscle, and thyroid cartilage, and is conical, bending slightly backward.
Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoid, thyroarytenoid, and interarytenoid muscles.
The phonatory muscles are divided into adductors ( lateral cricoarytenoid muscles, arytenoid muscles ) and tensors ( cricothyroid muscles, thyroarytenoid muscles ).
The aryepiglottic muscle together with the transverse arytenoid and the thyroarytenoid work as a sphincter and close the larynx as we swallow or cough.
For more severe VCD cases, physicians may inject botulinum toxin into the vocal ( thyroarytenoid ) muscles to weaken or decrease muscle tension.
