Action
When the digastric muscle contracts, it acts to elevate the hyoid bone.
If the hyoid is being held in place (by the infrahyoid muscles), it will tend to depress the mandible (open the mouth).

Famous quotes containing the word action:
“We call the intention good which is right in itself, but the action is good, not because it contains within it some good, but because it issues from a good intention. The same act may be done by the same man at different times. According to the diversity of his intention, however, this act may be at one time good, at another bad.”
—Peter Abelard (1079–1142)
“Suit the action to the word, the word to the action, with this special observance, that you o’erstep not the modesty of nature.”
—William Shakespeare (1564–1616)
“Not rarely, and this is especially true of wives and mothers, the motive behind assuming a disproportionate share of work and responsibility is completely unselfish. We want to protect, to spare those of whom we are fond. We forget that, regardless of the motive, the results of such action are almost always destructive and unproductive.”
—Hortense Odlum (1892–?)
