I love your videos. This one is so interesting and fun to listen to! I would love to see a full screen shot of the drawing at the end so I can screenshot it and print it out!!! Thank you for what you do.
I have congenital hydrocephalus and I will be 35 years old in September. I have been having extreme headaches, nausea, vertigo, intermittent vomiting. Can you please do a video with everything labeled as it is for hydrocephalus patient?
Very good vide/ drawing has helped me understand it more. Just one thing at 7:30 you labelled the transverse sinus when i believe according to my notes and the tinternet it is the straight sinus. :)
Hi Susan. Very informative, nice drawing nice handwriting, clean voice explanation. OK, spinal fluid produced in the brsin and spread down to the spinal cord. Question is: Does the spinal fuid yhat is slready located in lumbar will climb back again up in to the brain via subarachnoid space? Is that what you mean by circulations? If it does, which way does it go back up to the brain? There two different tube or somekind to go down or up and what pushes/force the fluid back to the brain. The reson I ask I se you explain clearly how is circulate in the brain you only show one way stream of CFS fown to spinal cord via central cord and subarach, no explanation how the CSF in lumbar circulate back to the brain. Can you explain this. Thanks
Ricard, Great question. In recent years, arachnid villi-like structures have been found lower in the spinal cord, so that's good evidence that it does reabsorb into the blood at locations in the spinal cord. But it is not totally elucidated, at least from the articles I have read! Have a great day, Susanna
+susannaheinze Thanks, the reason I ask is. I have a lost of neurons in my VLPO and some other part of CNS from heavy dose of neurotoxin that disturb a communication of my PNS and my brain that might be the cause of me have a fatal sleeping disability (not insomnia but zero sleep for already 6 month) and planning to have stemcell terapy. The stemcell doctor say that they might transplant the cell via lumbar puncture in order to send them to the brain area via subarachnoid instead of using cranial stereotactic injection to the specific area in the brain. I am just curious how the cell will climb up directly since I am also affraid that the CSF stream from my spinal to the brain already disturbed. Would it be possible for you to ask the professor in your field?
First off, this is a medial view not a posterior. Second off, what she is labeling at 7:30 is the continuous sinus which is going into the confluence of sinuses. THEN the transverse sinuses expand bilaterally into the sigmoid sinuses. But overall, good.
CSF drains in to the Superior Sagittal Sinus which along the path of other venous sinuses and drain into the Internal Jugular Vein (a vessel) that will drain eventually into the Superior Vena Cava
KimxMuhaha Hello! Thank you for your question! CSF is formed by filtering blood, and so it "rejoins" the blood once it has circulated around the brain. Hope that makes sense!
Thank you for replying! So, essentially the choroid plexuses are capillaries that form CSF by filtering the blood and would it be correct to say that CSF was originally from blood?

Thank you so much for talking about!!!!!!
This taught me more than like... All my profs....
you made it look super easy to understand. my professor could not do what you did. very helpful. very simple. very amazing! thank you so much!
yeah !! :P iam in my 6th year and i find this helpful !! :P
My daughter has severe congenital hydrocephalus and I found your videos very informative and helpful :) xx
I too have Hydrocephalus and even have slit ventricles..
Thank you so much; I appreciate these videos
thank you very much … anatomy class for2 h i did not understand any thing from it but you make it very easy and simple ….
Thank you very much , really it is very informative video ..
this is amazing thank you :)
i love your channel!!!! THANK YOU!!
Gracias! Excelente explicación!
can we have your pictures? its amazing thank you very much :)
Awesome ! Thanks! Good and simple!
Thank you! great video
Excellent

Very good vide/ drawing has helped me understand it more.

She has a posterior view. According to my book she is right... it is transverse sinus.

Is there any csf in subdural space;between arachnoid mater and duramater?
First off, this is a medial view not a posterior. Second off, what she is labeling at 7:30 is the continuous sinus which is going into the confluence of sinuses. THEN the transverse sinuses expand bilaterally into the sigmoid sinuses. But overall, good.
....But Overal super Excellent....
hi Susan, it's me again. Could you find out if CSF has direct contact with VLPO? Thanks
is the condition series for a person who has fluild on the brain?
I wanted to know where does CSF reenter the circulatory system
CSF drains in to the Superior Sagittal Sinus which along the path of other venous sinuses and drain into the Internal Jugular Vein (a vessel) that will drain eventually into the Superior Vena Cava
there is no reentry but new csf being produced, however its seem like rotate along the whole brain and spines
Hi, I'm confused why CSF is "rejoined" to the blood supply after entering the arachnoid villi. Has it joined the blood supply before?

KimxMuhaha yes! it's very similar to plasma (the watery part of blood without blood cells)
susannaheinze Can Very dark urine, negative for infection, be correlated? Onset two - three weeks post mild TBI.
Hello -- I am not familiar with a link between urine color and traumatic brain injury. Thank you for your question, and I hope you find a good answer!
Thank you so much for talking about!!!!
