Actions

A considerable number of the fibers of the Thyreoarytenoideus are prolonged into the aryepiglottic fold, where some of them become lost, while others are continued to the margin of the epiglottis. They have received a distinctive name, Thyroepiglotticus or Thyroepiglottic, and are sometimes described as a separate muscle.
