Actions
The thyroarytenoid muscle, consisting of two parts having different attachments and different directions, are rather complicated as regards their action.
Their main use is to draw the arytenoid cartilages forward toward the thyroid, and thus relax and shorten the vocal folds.
But, owing to the connection of the deeper portion with the vocal fold, this part, if acting separately, is supposed to modify its elasticity and tension, while the lateral portion rotates the arytenoid cartilage inward, and thus narrows the rima glottidis by bringing the two vocal folds together.

Famous quotes containing the word actions:
“The course of my long life hath reached at last
In fragile bark oer a tempestuous sea
The common harbor, where must rendered be
Account for all the actions of the past.”
—Henry Wadsworth Longfellow (18071882)
“If one had to worry about ones actions in respect of other peoples ideas, one might as well be buried alive in an antheap or married to an ambitious violinist. Whether that man is the prime minister, modifying his opinions to catch votes, or a bourgeois in terror lest some harmless act should be misunderstood and outrage some petty convention, that man is an inferior man and I do not want to have anything to do with him any more than I want to eat canned salmon.”
—Aleister Crowley (18751947)
“We should often be ashamed of our finest actions if the world understood all the motives behind them.”
—François, Duc De La Rochefoucauld (161380)
