Neural Tube Closes

Famous quotes containing the words tube and/or closes:

    One of the great natural phenomena is the way in which a tube of toothpaste suddenly empties itself when it hears that you are planning a trip, so that when you come to pack it is just a twisted shell of its former self, with not even a cubic millimeter left to be squeezed out.
    Robert Benchley (1889–1945)

    There where the course is,

    The riders upon the galloping horses,
    The crowd that closes in behind....
    William Butler Yeats (1865–1939)
