Neural Tube Defect
Neural tube defects (NTDs) are one of the most common birth defects, occurring in approximately one in 1,000 live births in the United States. A NTD is an opening in the spinal cord or brain that occurs very early in human development. In the 3rd week of pregnancy called gastrulation, specialized cells on the dorsal side of the fetus begin to fuse and form the neural tube. When the neural tube does not close completely, an NTD develops.

Famous quotes containing the words tube and/or defect:
“The last best hope of earth, two trillion dollars in debt, is spinning out of control, and all we can do is stare at a flickering cathode-ray tube as Ollie “answers” questions on TV while the press, resolutely irrelevant as ever, asks politicians if they have committed adultery. From V-J Day 1945 to this has been, my fellow countrymen, a perfect nightmare.”
—Gore Vidal (b. 1925)
“The child realizes to every man his own earliest remembrance, and so supplies a defect in our education, or enables us to live over the unconscious history with a sympathy so tender as to be almost personal experience.”
—Ralph Waldo Emerson (1803–1882)
