What Structure in mammalian embryos that develop into the brain and spinal cord?
Neural tube
If the posterior portion of the neural tube failed to develop properly?
spinal cord may be affected
If the posterior portion of the neural tube failed to develop properly the?
This part of the cord affects the legs and back.
What would be affected if the posterior portion of the neural tube fail to develop?
The lower limbs and muscles and the bladder and bowel.
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.
In a toad embryo the neural tube does what?
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 condition does neural tube defect cause in a newborn?
This defect may cause children to develop an accumulation of cerebrospinal fluid on the brain (hydrocephalus ).
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
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.
When does spina bifida occur in pregnancy?
Spina bifida occurs during the first trimester. Spina bifida is in a class of birth defects known as neural tube defects. The neural tube eventually develops into the spinal cord, brain and the tissues that enclose them. In a normal pregnancy the tube forms early and closes by the twenty eighth day. With spina bifida portions of the neural tube fail to develop properly causing defects of varying severity in the spinal cord and back bones. This is a complicated topic and you can read more about it at the related link.
Connects the brain to the spinal cord?
