The single most exhaustive explanation of a commonly understood rendering for anatomical study.

thank you so much for this video. I was trying to understand how the csf was produced in the brain it's circulation and it's reabsorption. In order to understand my brother in law's ICP after his hemorrhagic stroke. Thanks again

This well-known diagram is by Frank Netter MD!

a minute to explain that this is cut in half?

[AlexHop1]

Thanks very much. Very explanatory!

I was diagnosed with intracranial hypotension a couple days ago. I want to know as much as possible about it before I start treatment. Are there any statistics comparing csf levels and effectiveness of treatment in relation to the amount of pressure recorded at first lumbar puncture.

thank you!!! neurophysiology exam tomorrow and my textbook is useless when it comes to explaining CSF flow. awesome video.

so tela choroidea contains pia matter surrounded by ependyma, and its irregular edge is called choroid plexus which produces CSF. CSF in the posterior (occipital) horn of the lateral ventrice is quite interesting because hippocampus is forming medial half of the floor of occipital horn of lateral ventrice - and the ventricular surface is surrounded by a thin sheet of white matter. Is all of the borders of the ventricular cavity surrounded by this thin sheet of white matter? - 1.year med student

until it equals the effective filtration pressure...when it counter balance and stop further production of fluid....but that is far enough pressure to cause harm for to the brain and brain tissue degenerates and shrinks and the high pressure space dilates to cause slow and progressive damage to brain tissue...for newborn babies whose skull is not rigid it also start getting bigger to accommodate that increased volume and gives rise to a condition called Hydrocephalus....Thank you....

the fluid...but in csf its a different reason what cause the pressure gradient....there are places where fluid is being produce that added fluid increasing the pressure...and there are places where csf being absorbed that removal of fluid is creating a sucking action or negative pressure thus there is a pressure gradient and fluid flows from high pressure to low pressure area by default...if there is any blockage on the path way then pressure keeps rising in that isolated part...

this video is the best description and explanation csf production and circulation among those i looked....for the mechanism of circulation of csf or the factors that affect ICP i want to add this....as for any circulatory system there is always a pressure gradient and fluid circulates from high pressure area to low pressure area..as of our blood circulation where the mean arterial pressure is 98 mm Hg and the rigt atrial pressure is virtually 0 ..so the pressure gradient is 98-0= 98 which drives

@scuzzulus ependymal cilia are microscopic structures neither sufficient nor necessary to "push" CSF around, though that's a reasonable guess in the absence of further information. If you'd like to see a better use for those cilia see lightDOTsimanonokDOTcom
