Isn't F) the IV Ventricle and when the CSF "leaves" the ventricular system is also leaving the IV V? I read CSF leaves the IV v and enters the cisternae (large subarachnoid spaces) through 2 foramen of Lushka and 1 middle foramen of Magendie.
From Lushka CSF pass to Cisterna Pontis
From magendie CSF pass to Cisterna Magna
I guess I would pick G) but it'sa little tricky, damn it

No way, it's not G, it's F, cause at the end is says "collects" and yeah CSF is produced in the plex.ch. of IV ventricle. agggh, they got me >( very good reet!

The question asks where the CSF "leaving" via the foramen of magendie collects in...i'd say it would be the subarachnoid space...and G is the cisterna magna which is part of the subarachnoid space...so it would have to be G...good question Believe!....the illustration is awesome too!!

ok cyra now you got me again  what a way to ask the qs? I was thinking, if they say "collects" the CSF, CSF is produced in all ventricles (lat, III, IV) but it is not 'collected' there, it's produced by the chor. plex. and drained towards the Subarachnoid Space, maybe we could call it "collection" to what happen in the Cisternae because they are enlarged spaces of Subarach Space? so CSF can be somehow collected there before it is completely reabsorbed?
Damn qs, I give up on qs like this, the concept is there but I don't really know what are they asking for? it sucks, these qs are so tricky.
but I would go for G) Cisterna Magna
