So today about this question, first of all you need to know that what are the ventricles of the brain? how many are there and how are they interconnected with each other? ventricles of brain are number one we have just a sec.
00:20
Lateral ventricles.
00:29
Number two we have third ventricles.
00:34
Number three we have fourth ventricle.
00:37
Okay? so these are a part of corroid plexus and all of these together makes or produces csf.
00:51
Cf is a csf is produced by them.
00:54
Csf is your cerebrospinal fluid.
00:57
Let us draw a linear diagram to understand the interconnection of all these ventricles.
01:04
Number one we have on the top we have lateral ventricles abbreviated as lv.
01:10
Then we have your third ventricle over here third ventricle.
01:20
Lateral ventricle and third ventricle are connected by the phoromen of monroe.
01:28
Now we have below third ventricle we have foramen of, sorry, fourth ventricle.
01:41
And this fourth ventricle and third ventricle are connected with each other.
01:46
Via cerebral aqueduct or the aqueduct of sylvia's aqueduct of silvius okay so it is these through these three ventricles the c sf flows into the subarachanite space via foramen of luska which are two and and pharomen of magendii one so now with that we have discussed about our ventricles if you will observe the given diagram you can easily appreciate that the structure a is your ferrumen of monroe and your structure b is your lateral ventricles structure c are your third ventricles structure d is your cerebral aqueduct or aqueduct of silvius e is your fourth ventricle and f is your central canal so this question is asking you about certain points or the labelings that you have to fill in your bloods the question is asking you that the structure labeled dash and called dash makes the holds most of the cerebrospinal fluid.
03:15
There can be two approaches for this question to solve this question.
03:20
Either you can relate it with the diagram and just match that which option is correct by the diagram and the alphabet.
03:28
If you will look at e, so is e the fourth ventricle, let's see this.
03:34
In your diagram, yes, e is fourth ventricle.
03:37
So this can be our possible answer...
