Importance
If at all present, the sphenoidal emissary foramen gives passage to a small vein (vein of Vesalius) that connects the pterygoid plexus with the cavernous sinus. The importance of this passage lies in the fact that an infected thrombus from an extracranial source may reach the cavernous sinus. The mean area of the foramen is small, which may suggest that it plays a minor role in the dynamics of blood circulation in the venous system of the head.

Famous quotes containing the word importance:
“We have been told over and over about the importance of bonding to our children. Rarely do we hear about the skill of letting go, or, as one parent said, “that we raise our children to leave us.” Early childhood, as our kids gain skills and eagerly want some distance from us, is a time to build a kind of adult-child balance which permits both of us room.”
—Joan Sheingold Ditzion (20th century)
“People without imagination are beginning to tire of the importance attached to comfort, to culture, to leisure, to all that destroys imagination. This means that people are not really tired of comfort, culture and leisure, but of the use to which they are put, which is precisely what stops us enjoying them.”
—Raoul Vaneigem (b. 1934)
“The importance to the writer of first writing must be out of all proportion of the actual value of what is written.”
—Elizabeth Bowen (1899–1973)
