Neural tube defects (NTDs) are a group of birth defects in which an opening in the spine or cranium remains from early in human development. In the third week of pregnancy called gastrulation, specialized cells on the dorsal side of the embryo begin to change shape and form the neural tube. When the neural tube does not close completely, an NTD develops.
Specific types include: spina bifida which affects the spine, anencephaly which results in little to noWikipedia · Nội dung trong CC-BY-SA giấy phép - Mọi người cũng hỏi

Le tube neural désigne le système nerveux primitif des embryons des chordés.Il se forme lors de l'étape de neurulation, entre les 19 et 28 e jours du développement embryonnaire humain.. Il forme le système nerveux central chez le fœtus et chez l'humain. Embryologie. Il se forme par invagination de la plaque neurale en une gouttière, puis par convergence et fusion de ses bords.

- Para el desarrollo de un individuo adulto, en primer lugar es necesario la fecundación, es decir, la formación del cigoto. En este momento, la primera célula empieza a dividirse haciendo una serie de mitosis del cigoto para dar lugar a la mórula, siendo el embrión en los primeros estadios de su desarrollo donde se forma una especie de bola sólida de unas pocas células. La blástula sigue …

Neurulation - Wikipedia
https://en.wikipedia.org/wiki/Neurulation- Neurulation refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube. The embryo at this stage is termed the neurula. The process begins when the notochord induces the formation of the central nervous system by signaling the ectoderm germ layer above it to form the thick and flat neural plate. Th…

In the developing nervous system, the basal plate is the region of the neural tube ventral to the sulcus limitans.It extends from the rostral mesencephalon to the end of the spinal cord and contains primarily motor neurons, whereas neurons found in the alar plate are primarily associated with sensory functions. The cell types of the basal plate include lower motor …

Neurulation. Neurulation is a process in vertebrate embryos at the neurula stage in which the neural tube is formed. There are two types of neurulation: primary and secondary neurulation.Primary neurulation refers to the formation and inward folding of the neural plate upon itself to form the neural tube.
- https://en.wikipedia.org/wiki/Neural_plate
The neural plate is a key developmental structure that serves as the basis for the nervous system. Opposite the primitive streak in the embryo, ectodermal tissue thickens and flattens to become the neural plate. The region anterior to the primitive knot can be generally referred to as the neural plate. Cells take on a columnar appearance in the process as they continue to lengthen and …
