Neural tube defects. A failure in closure of the neural tube during the first trimester of fetal development. It is one of the most common types of developmental anomalies occurring in 1 of every 1000 births. Myelomeningoceles and anencephaly are common examples.

The act of neurulation. The closure of the neural tube during embryogenesis or the emulation of same.

The stage of fetal development when the neural tube begins its transformation into central nervous system. The process begins with thickening of the endoderm to form the neural plate. The plate then folds or rolls on itself to form the neural tube. The neural tube is destine to eventually form the central nervous system, ultimately differentiating into the brain and spinal cord.
