The neural tube is the part of the development of the central nervous system in a developing embryo. What is pretty amazing about this is that within the first 4 weeks of development from conception, the entire framework of the central nervous system will have finished forming! Around day 18, the neural plate appears at the midline of the thickening of the ectoderm, the outermost layer of the germinal sac. Essentially what happens over the next couple of days is that the neural plate forms a depression, which eventually is pushed down and separated from the original cell layer by the fusion of the neural crests, resulting in the formation of a neural tube - this is rather hard to explain without a proper diagram!
The neural tube develops into the brain and spinal cord during embryonic development.
Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.
Folic acid is a critical nutrient for proper neural tube development, as it plays a key role in DNA synthesis and cell division. Adequate folic acid intake, especially during the early stages of pregnancy, can help prevent neural tube defects such as spina bifida.
Neural tissue originates from the ectoderm layer of the developing embryo. This layer gives rise to the neural tube, which later differentiates into the central nervous system (brain and spinal cord) and the peripheral nervous system. Neuromesodermal progenitors are involved in the development of both neural and mesodermal tissues during embryonic development.
The ectoderm layer of the embryo gives rise to the tissues of the nervous system through a process called neurulation. During neurulation, the neural tube forms from the ectoderm, which eventually gives rise to the brain and spinal cord. The cells within the neural tube differentiate into various types of neural cells that make up the nervous system.

if measurement of neural tube is greater than 2.5mm indicates down syndrome
Alpha-fetoprotein (AFP) is a substance that is measured in the maternal serum when a neural tube defect is suspected. High levels of AFP may indicate a neural tube defect in the fetus.

The neural tube closes around the 28th day of gestation, so that would be at the end of the fourth week.
Nervous Tissue
In the embryo the neural tube forms the central nervous system in the fetus, which is the brain and spinal cord. The reason pregnant women are given folic acid supplementation is to help prevent neural tube defects, which can range from fairly benign all the way to anencephaly (where the baby is born without a brain).
The neural tube
Neural Tube
The neural tube is the embryonic predecessor of the brain and spinal cord. Which means, most of what it "does" is develop into a brain and spinal cord. The neural tube is initially formed almost exclusively of stem and progenitor cells. Over time, these stem and progenitor cells adopt specific identities and begin to differentiate neurons and later glial cells and these cells begin forming neural circuits. By the time the neural tube has developed to a point where it is capable of carrying out rudimentary neurological functions, the nomenclature is generally changed to brain and spinal cord rather than neural tube.

Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.
