Actions
Given that the origin is on the medial side of the lateral pterygoid plate and the insertion is from the internal surface of the ramus of the mandible down to the angle of the mandible, its functions include:
- Elevation of the mandible (closes the jaw)
- Minor contribution to protrusion of the mandible
- Assistance in mastication
- Excursion of the mandible; contralateral excursion occurs with unilateral contraction.

Famous quotes containing the word actions:
“Our actions seem to have their lucky and unlucky stars, to which a great part of that blame and that commendation is due which is given to the actions themselves.”
—François, Duc De La Rochefoucauld (1613–1680)
“A young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end that is aimed at is not knowledge but action. And it makes no difference whether he is young in years or youthful in character.”
—Aristotle (384–323 B.C.)
“Coercion may prevent many transgressions; but it robs even actions which are legal of a part of their beauty. Freedom may lead to many transgressions, but it lends even to vices a less ignoble form.”
—Karl Wilhelm Von Humboldt (1767–1835)
