Palatopharyngeus Muscle - Action

Action

The palatine velum is slightly raised by the levator veli palatini and made tense by the tensor veli palatini; the palatopharyngeus muscles, by their contraction, pull the pharynx upward over the bolus of food and nearly come together, the uvula filling up the slight interval between them.

By these means the bolus is prevented from passing into the nasopharynx; at the same time, the palatopharyngeus muscles form an inclined plane, directed obliquely downward and backward, along the under surface of which the bolus descends into the lower part of the pharynx.

Famous quotes containing the word action:

    Let him [the President] once win the admiration and confidence of the country, and no other single force can withstand him, no combination of forces will easily overpower him.... If he rightly interpret the national thought and boldly insist upon it, he is irresistible; and the country never feels the zest of action so much as when the President is of such insight and caliber.
    Woodrow Wilson (1856–1924)

    The Oriental philosophy approaches easily loftier themes than the modern aspires to; and no wonder if it sometimes prattle about them. It only assigns their due rank respectively to Action and Contemplation, or rather does full justice to the latter. Western philosophers have not conceived of the significance of Contemplation in their sense.
    Henry David Thoreau (1817–1862)

    The philosophy of action for action, power for the sake of power, had become an established orthodoxy. “Thou has conquered, O go-getting Babbitt.”
    Aldous Huxley (1894–1963)
