Because anencephaly is caused by abnormalities of the neural tube, it is classified as a neural tube defect. Because the neural tube fails to close properly, the developing brain and spinal cord are exposed to the amniotic fluid that surrounds the fetus in the womb.
Spina bifida is among a group of birth defects called neural tube defects. When the fetus is developing, its central nervous system begins as a tube early in its life that eventually forms the brain, spinal cord, and the surrounding tissues. By the fetus' 28th day of life, this tube should be closed.
