thyroarytenoid muscle การใช้

It runs between the vestibular fold, thyroarytenoid muscle, and thyroid cartilage, and is conical, bending slightly backward.
The phonatory muscles are divided into adductors ( lateral cricoarytenoid muscles, arytenoid muscles ) and tensors ( cricothyroid muscles, thyroarytenoid muscles ).
The folds are covered on the surface by laryngeal mucous membrane which is supported deeper down underneath by the innermost fibres of the thyroarytenoid muscle.
This break is a sudden gap in sound which occurs when the thyroarytenoid muscles suddenly decrease their activity and the cricothyroid muscles begin to function.
A considerable number of the fibers of the thyroarytenoid muscle are prolonged into the aryepiglottic fold, where some of them become lost, while others are continued to the margin of the epiglottis.
