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.

What stage is the embryo when it forms a neural tube?
In the 2nd week of pregnancy before most women know they are pregnant.
What is the neural tube formed by the fusion of?
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).
Will the neural tube develop into the brain and the spinal cord?
Yes. The neural tube is a long, hollow structure that extends about the full length of the developing embryo. The tube itself gives rise to both components of the central nervous system (CNS): the brain and the spinal cord.
What is a neural tube?
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 of vertebrates develops during morphogenesis of the nervous system by the?
This occurs as a result of the folding of ectoderm tissue. The ectoderm is a type of germ cell layer present in a young embryo.
What does the walls of the diencephalon form?
In the embryo the walls of the diencephalon forms at neural tube that begins the process of the fore brain. In adults, the diencephalon is located towards the upper end of the brain stem.
What is the function of hensen's node in chick embryo?
forms neural opening
What is considered the normal range for neural tube measurement in a fetus?
if measurement of neural tube is greater than 2.5mm indicates down syndrome
Is it true that the embryo normally attaches to a fallopian tube?
No. That is false. Embryo normally get attached to uterine cavity. It is abnormal and dangerous for the embryo to get attached to fallopian tube.
What develops into the back bone?
Neural tube.
What week of gestation does the neural tube close?
The neural tube closes around the 28th day of gestation, so that would be at the end of the fourth week.
Connects the brain to the spinal cord?
Nervous Tissue
