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:
“When a man’s life is destroyed or damaged by some wound or privation of soul or body, which is due to other men’s actions or negligence, it is not only his sensibility that suffers but also his aspiration toward the good. Therefore there has been sacrilege towards that which is sacred in him.”
—Simone Weil (1909–1943)
“The course of my long life hath reached at last
In fragile bark o’er a tempestuous sea
The common harbor, where must rendered be
Account for all the actions of the past.”
—Henry Wadsworth Longfellow (1807–1882)
“It has lately been drawn to your correspondent’s attention that, at social gatherings, she is not the human magnet she would be. Indeed, it turns out that as a source of entertainment, conviviality, and good fun, she ranks somewhere between a sprig of parsley and a single ice- skate. It would appear, from the actions of the assembled guests, that she is about as hot company as a night nurse.”
—Dorothy Parker (1893–1967)
