Full article >>>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.
Full article >>>A congenital defect of the central
nervous system, including the
spinal cord, skull and brain, resulting from failure of the
neural tube to properly close during fetal development.

Normally the closure of the
neural tube occurs around the 30th day after
fertilization. However, if something interferes and the tube fails to close properly, a
neural tube defect will occur.

Full article >>>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.

proteins, so it excludes some newborn
screening, prenatal tests for
neural tube defects, and many tests currently used by geneticists to make diagnoses.
Full article >>>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.
