🔴 Neural Tube Defects

🔸 The most severe neural tube defect is when the neural tube simply doesn't close up at all and that's something that's called 'craniorachischisis'.

🔸 Remember that the neural tube closes in both directions and then there's the last little bit at the back end and at the front end. Let's talk about what happens if it doesn't close in the back end. That's called Spina Bifida or open Spina Bifida.

🔸 The back end of the spinal cord where the lumbar cord joins the sacral cord is not covered; it's externalized. There it's not covered by skin, it's not covered by bone, it comes out and it can loop around.

🔸 The additional problem is that because the spinal cord takes this extra loop, that extra length actually pulls on the brain.

🔸 That pulls the cerebellum out and it can produce many serious consequences. It's going to interfere with brain function. So, you have a spinal cord defect, producing brain problems.

🔸 This can not only interfere with brain function, it can also interfere with the flow of cerebral spinal fluid. So these individuals can develop hydrocephalus.

🔸 The other major neural tune defect happens when the anterior neuropore does not open. And in that case, what you got is something called Exencephaly. And what that means is what now the brain is not covered.

🔸 And the brain is not covered starting at day 28. So, the end of the 4th week through the rest of gestation, what happens is the brain essentially disintegrates.

🔸 So, if these embryos come to term, they have very little brain left and they're called anencephalic. The initial problem is the Exencephaly but through time this becomes Anencephaly, which is lethal.

🔸 There are things that can happen to the neural tube after day 28 and one example is Encephalocele.
And in this case, there is a seal or a cyst, essentially, which is externalized which contains either just cerebrospinal fluid or cerebrospinal fluid and brain.

🔸 The good news here is that we can do something about preventing neural tube defects from occurring. The problem here is that neural tube closure happens in the fourth week of gestation when many women don't even know that they're pregnant.

🔸 So how do you do that? What governments have decided to do Is to supplement all grains with folate, for reasons that are largely unclear prevents about 70% of the neural tube defects that occur.

A delicate remote control operation to remove a tracking collar from a tiger on an epic 13-month trek through India has been carried out to avoid the device choking the animal.
