Neural tube From Wikipedia, the free encyclopedia Jump to: navigation, search ...
Neural tube [L. neuralis - nerve]. A tube of tissue formed by a thickening and rolling up of the neural plate during embryonic neurulation. It will later form the brain and spinal cord of the animal.
Neural Tube Defects Neural tube defects (NTD) such as anencephaly and spina bifida and also cleft lips are examples of multifactorial traits which show a threshold effect.

Development of the neural tube starts from the neuroepithelium, which is a flat sheet of cells and it has the underlying mesoderm derivative of the notochord. The spinal chord, which ultimately is formed from the neural tube, is a solid rod.
11 It is derived from the entoderm, and consists of a rod of cells, which lies on the ventral aspect of the neural tube and reaches from the anterior end of the mid-brain to the extremity of the tail.

In the development sequence, the neural plate forms the neural tube which then forms the CNS (central nervous system), comprised by the spinal cord and the brain.
" Note that this definition does not include proteins, so it excludes some newborn screening, prenatal tests for neural tube defects, and many tests currently used by geneticists to make diagnoses.
Elevated levels of AFP may indicate that the baby has a neural tube defect such as spina bifida (incomplete closure of the spinal column) which can lead to paralysis of the lower limbs, repeated urinary tract infections, ...
This ectoderm grows up into two longitudinal folds, forming the neural folds stage. In time the lips of the folds fuse to form the neural tube. The neural tube eventually develops into the brain and spinal cord.
Folic Acid a B vitamin noted for its prevention of neural tube defects if taken in early pregnancy (foli = a leaf) Fossil the preserved remains of a formerly-living (prehistoric) organism (foss = ditch trench; fossil = dug up) ...
Chordates have the cells that will form the nervous system fold into a neural tube (which will eventually form the spinal cord). The mesoderm forms the notochord (which will eventually form the vertebrae).
In addition, folate is vital during fetal development, thus folate deficiency in pregnant women can lead to neural tube defects in their offspring.
neurulation External changes along the upper surface of a chordate embryo that result in the formation of the neural tube. neuston Organisms that live on the surface of the sea. neutral selection See genetic drift.
neurula The stage of a vertebrate embryo when gastrulation is largely finished and a neural plate is forming, ending with formation of the neural tube.
