The video is very helpful but The CSF will pass From 4th ventricle to subarachnoid space through a median foramen named foramen magendie and two lateral foramina of luschaka and CFS will not be present in subdural space its will present in subaracnoid space only. Please correct it . Tanx

[@susannaheinze]

Thank you for your comment. I generally try to simplify the content and avoid the most specific terms for the foramina. You are correct that the CSF only circulates in the subarachnoid space. I'll make an annotation at that point in the video to correct this!

[@exceptionalprogression3763]

I needed to know this too. Thanks for pointing that out.

[@susannaheinze]

K Simpson yes I appreciate when viewers point out areas that the videos can be improved!

[@SuperMohd1985]

Right..the foramen of Magendie open into the cisterna magna and the Lateral foramina of Luschka opens to pontine cistern.

[@technicaltipsandtricks4428]

Yes i Agree with your Correction. ♻

[@yellowtevo]

Each time I come on to one of these videos Ima like "oh shoot, how am I gonna draw THAT?? lol. Thank you for your videos, very helpful. I always go the the very end first so that I can see how much room I'm gonna need.

[@ilhamjirde2954]

I thought that the choroid plexus of the lateral ventricles are located on its floor not the roof? Correct me if I am wrong

[@Squshie00]

Your videos are really nice, methodical, and filled with great information. I love the different colors and explanation of the process. It's just like watching an animation video. Thanks for creating this!

[@amandaford6019]

I'm truly glad I came across your video! It explained it perfect and now it makes sense!! Way better than my instructor... I'll be be back for other subjects as well as I continue to make way thru nursing school!! Thanks again!

[@heartmomma6460]

I feel like my brain has been being smashed into others but trust me I have not made millions a year in any job I've had nor been an NFL player. I wish since savings runs away fast when you add up tissue costs & hours unable to work because I only felt better lying with my head down in bed. Thinking for the longest time I had sinus issues from allergies. Wasn't figured out until I had surgery for a morphine pain pump implant - lucky me I found out I had a 2nd cause of CSF leak.

[@michaelmcveigh603]

The choroid plexus is on the floor of the lateral ventricle, not the roof. Other than that this is a great video.

[@susannaheinze]

Thank you for pointing this out! I did not know this--I shall research it further.

[@marymunluo7202]

I was confused then I saw your comment!!! Now I'm sure..thnks

[@blueworldadam]

a girl making this video

[@landrewmackinnon4888]

agree 100%. Was going to make the same comment. On let's not forget the 4th ventricle. But let me get firthur in the video.

[@dannichols6261]

Yes! It's very unfortunate for visual processors to see it shown on roof of lateral ventricle, at least in the anterior horn it should be on the floor, and maybe also down the foramen of monro into and onto the roof of the third ventricle.

[@yvonnepeters1914]

That whole outline in blue IS THE ALL SEEING EYE OF HORUS just as depicted in the pyramids!!

[@animallover8779]

It's all fun and games until you have a csf leak I had one and took years to even be taken serious

[@jameshansen958]

Thank you for having nice hand writing. Added bonus to the presentation

[@cathykirkland3740]

I had Achnoid cyst removed that was the size of t1- t4 very painful surgery

[@evelisisdavis7242]

Thank you for talking about and showing!!!!!

[@haileehimple5746]

These videos are AMAZING! Drawing, coloring and labeling along with you. This is exactly my learning style, many thanks!! You are awesome!

[@BeyMaster85]

What came first Consciousness or Matter?

[@valeriehughey7993]

living with CSF affected my life how it affects your learning,Motor skills,reflexis. I never felt so miserable.

[@ggonsg]

You are an amazing teacher!! Love your videos!!!

[@glorynetwork8918]

Susan. I am praying for someone who has been diagnosed to have a problem with CSF blockage (19 year old has been getting headaches for years). What are the main causes of this block of flow? Thanks! Your videos are very informative.

[@rebeccadelforge3089]

Is there any way you could upload the “blank”pages for us to download and print? I would love to follow along and color in and label my own for notes. Thank you for your videos!

[@ShanteGaston]

So glad I've found these videos. Currently preparing for finals! These seem to help a lot!

[@BellaBloodLust]

You'll rock it girl! Good Luck! :)

[@ShanteGaston]

Bella BloodLust Thank you! Hope your finals went ok! Just finished my anatomy final today....I hope I passed lol this semester was so stressful

[@BellaBloodLust]

Oh man I feel you! I'm still tired and I was done on Monday! I'm pretty excited with my grades this semester, however my English Professor totally has OCD with 75% on any paper regardless of how worthy of 100% it was, so If anything, rage towards professors as usual not myself or grade lol :) B's & A's this semester :) Wishing you the same!

[@AishaAbdulbahar]

best thing to have happened to me all night long!!!!! thank you very much for this video. it has helped me so much.

[@caita1637]

By far the best explanation I've ever seen!

[@deborahnartey5976]

Check out Dr najeeb

[@lubnakauser3295]

Amazing videos! Thank you very much.. May god bless you!

[@pedrom.7916]

Hi! At min 12:30: You seem to imply that the subarachnoid and subdural spaces are the same. They're not! The subdural is a virtual space between the dura and the arachnoid. "Virtual" meaning that it normally contains nothing, let alone CSF!

[@amandaallen9460]

My Neurosurgeon said at today's appointment that I have severe slit ventricles and he seemed to indicate that having slipped ventricle syndrome is actually a good thing. But for my research and having been born with hydrocephalus, I know that that can cause its own issues. So now I'm confused.

[@cassielee13]

OMG SOOOO helpful!!!!! --current neuroscience student

[@archiewoosung5062]

Why are there four ventricles? Is the product from the lateral ventricles "refined" in some way but the others?

[@27capricia]

thank you..awesome presentation

[@basketballion]

Great video! Question: are you Velma from Scooby Doo?

[@jasnjakechatham8339]

I absolutely love this!,,,, thank you so much!

[@amandaallen1898]

Nice clear handwriting and good diagram.

[@amandaallen1898]

The ventricles look like 7.

[@PauloRLustosa]

Gostei muito da explicação. Obrigado.

[@deannahartman2878]

does the cerebral spinal fluid also functions as nourishment for the brain... carrying oxygen, glucose. water... from blood

[@fullaaliraqia6961]

nice - but whats the main structure of these Ventricles?

[@Burnz2much]

Tightly knit molecules.

[@trishlett40]

Hello I was wondering if anyone can tell me how accurate is the Stealth Neuro Navigation system in respect to guiding to the correct position? If guided incorrectly what would be the cause/s of this? Thank you.

[@mykhayloklen5194]

Very pedagogically and clearly explained. Thanks a lot, Susanna & greatings from the SAAG group in Lviv in UA!

[@doriansloan7747]

Hi Susanna ! I'm a first year nursing student and i wanted to thanks you for posting this video !! Do you sell your drawings as PDF at all ??

[@aryanmardanpour24]

Really great video.I recommend it to those who wanna refresh their knowledge...

[@kmelodyg]

This video was very helpful for me. I have Chiari Malformation and am researching CSF flow, it's origins, etc. Thank you for posting this!

[@bitar2042]

Very helpful ... may the god help me I'm now in neuroscience block

[@laurelinlorefield318]

Very clear and well paced. Great visual aids. I'm not as qualified to rate the content, but it seemed very accurate from what I do know. From a professor with decades of experience .... well done.

[@amandaallen1898]

Marvellous how the human brain works. It is a true miracle🙂

[@syamgovt6804]

I have a doubt, if lateral ventricle is 9.5 mm for 24 weeks faetus what will happen ? and it will increase in the future

[@deathtotruthers1]

This is a great video. Easy to understand, even for the lay person. Thank you.

[@11becket]

Thank you so much. You're explanations are so helpful and clear!

[@Gangsta0wns456]

I love this video and your website. Thank you so much!

[@vistawilliams6013]

really nice video. I also love the color. you voice is so peaceful which make it easy for others to follow. I will be checking out your other posts. Great job.

[@jasnjakechatham8339]

I absolutely love this! Thank you 🙏 so much

[@Muuip]

Great presentation! Very helpful, thanks for posting!

[@royarazavi3507]

This video is one of the best videos I ever seen. For me as a foreigner it was useful video. Thank you.

[@brookeheibel396]

The 3rd ventricle is not around the thalamus-- it is in between.

[@adejubujoy436]

9ccc video, great explanation. tanks.

[@Samrao007]

it's very nice to learn about csf and its pathway

[@hanifbasir7142]

amazing lesson of csf. it help me to answer the quizes.

[@pallavimehta9445]

Trauma causes blockage? Trauma as in stress?

[@wesporter2176]

Yes it does not take much force on the C1 atlas bone to block the flow through the upper neck region causing a lot of health issues including post concussion syndrome which I suffered with about 9 months before finding an upper cervical chiropractor.

[@faridamel]

damn why my teacher does not explain like that it even save time

[@mrRubal100]

Such a great video :) Thank you so much

[@ppatel0578]

Thank you! Great video.

[@alimd5817]

thank you my neuro exam is in 3 weeks and that helped alot

[@reyhane4210]

Thanks🌹🌹

[@yoyo8034]

thank you very much that was helpfull

[@sandisosigwaqa386]

Thanks a lot.May God bless you.

[@austinokuku317]

I love your hard writing.

[@austinokuku317]

I love your hard writing.

[@doctor02new]

Is it accurate to state that 'capillaries' produce CSF? The choroid plexus is a venous plexus. A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins.

[@thebeastinthegame]

+doctor02new The production of CSF happens via the ependymal cells which surround the blood capillaries. The ependymal cells make up the choroid plexus

[@austinokuku317]

I love your hard writing

[@austinokuku317]

I love your hard writing

[@lizaa154]

Thanx a million, gozillion times Susanna. You a sweetie pie!

[@DalTones79]

I think the spinal fluid is hot.. That's not a Paris Hilton quote.. people aught be aware that it isn't painful

[@DalTones79]

As far as I know, based on experience, a back injury untreated can cause head injuries in the form of soft fractures

[@Ravi93ahiran]

and very helpful and enjoyed

[@nancikole9406]

best video ever . thanks

[@Mehron74]

Awesome, fantastic series

[@nituchaturvedi2508]

It's really very helpful

[@HussainBlogs19]

God bless you :)

[@antoinetteesposito3098]

Very well explained :)

[@RobertMOdell]

In my head, the CSF is obviously under pressure at times. I sometimes can hear it "draining" directly toward the back of my head, almost every day around mid-morning. The sound is faint but a sort of high pitched crackling sound, as if spraying from a small opening under pressure. There are usually two or three surges of fluid, then it stops. It can be heard across a room when its very quiet. My kids have heard it a few times and describe it the same way: like fluid squirting through a copper pipe.

[@letsmakeitagoodworld]

RobertMOdell you have got to be kidding right... lol

[@PumpkinQueen1313]

jess davies no he's not. I have IIH and when my ICP raises too high because of this I get that fluid under pressure sound (similar to putting a finger partially over the end of a hose) as a large amount of fluid tries to squeeze through the foramen near the base of my brain all at one time.

[@nivekzurc]

skip to 12:30 for flow of CSF

[@Ravi93ahiran]

hi you tube is good video

[@blueworldadam]

oh and thank you for the vid loved it

[@wenyanxie7456]

thank you so much for sharing this video, i have learned a lot!

[@susannaheinze]

Wenyan Xie that is great to hear! I'm glad the video was useful!

[@mohammado.eshkalak3140]

Just Amazing. Greetings from UT Austin. Thanks for this videos. Learnt a lot. Awesome. Khan Academy is good but they do not relate what they teach to disease etc. You connect them to any possible diaorser. Thanks again. -Roya (KZbin account is for my husband).

[@susannaheinze]

Thank you for the encouraging comment! I find it always a difficult balance to include lots of applicable disease-information without making the videos too long! ;)

[@mohammado.eshkalak3140]

I beleive everything is in great balance. I really wished I could take your courses at Washington instead of the University of Texas at Austin. Your drawings and the way I redraw the same way you do is just Awesome. They stay in mind with this flow of information. Thanks a lot.

[@dr.farhadullah9484]

Liked your way of teaching. No doubt you did a great job but you did not even mention the role of ependymal cells in the formation of CSf. I appreciate your effort.

[@susannaheinze]

Thank you for taking the time to comment! You are right--I should have included more info about ependymal cells! I guess sometimes I cut things out because the video gets too long. This is an older video that I would like to remake and do a better job with. I do talk a little about ependymal cells in this video: kzbin.info/www/bejne/fGaah2eQe7J2qK8

[@susannaheinze]

My background is Cellular and Molecular Physiology, so I am definitely not a neuroscientist! My students primarily are interested in nursing, so for that reason I keep my videos as simple as possible.

Thank you so much! Your voice is so soothing and I love colours - thank you!

[@Megan-wb5gs]

there is a difference between the subarachnoid and subdural space!!!!!!!!!!!!!!!!!!!! please get your facts straight!

[@Wytejagyr]

I wonder if she is referring to it that way since the subdural space is a potential space. In the event of trauma or in cadavers it'll pop up, but in a healthy individual it is the subarachnoid space

[@exceptionalprogression3763]

Relax, she did a great job. People make mistakes. Learn how to be kind about it. Geez.

[@boscoechon7036]

Subdural space contains serous fluid where as the subarachnoid contains CSF, thanks a million

[@akanshujain6226]

lame and dull. put some better stuff into the video go study... deep into the topic.

[@michellegordon4211]

The content is just right for the majority of us.

[@wavavoom]

You know, the greatest problem in society is criticism. Mr Jain, if you believe you can do better please enlighten us with your series of youtube tutorials instead of being a spectator.

[@Dr.Iqbal.Hossain]

Unlucky we have people exist in our society like Jain,, who himself can do nothing but still dare to criticize those wise mind people who are providing free knowledge

[@shewantthem.d.2243]

She might be a medical student of whom posesses the benevolence to pass on her knowledge, however, uninformative it may be it is the gesture I value more; although the knowledge is paramount as well.
