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:
“Though with their high wrongs I am struck to the quick,
Yet with my nobler reason gainst my fury
Do I take part. The rarer action is
In virtue than in vengeance.”
—William Shakespeare (15641616)
“Do you suppose that sacrifice is the hallmark of moral action?Just stop to consider whether sacrifice is not involved in every action that is done with deliberation, the worst as well as the best.”
—Friedrich Nietzsche (18441900)
“The moment we choose to love we begin to move against domination, against oppression. The moment we choose to love we begin to move towards freedom, to act in ways that liberate ourselves and others. That action is the testimony of love as the practice of freedom.”
—bell hooks (b. c. 1955)
