Dear Dr. Webster, thank you for making your videos available free of charge on TH-cam. I am very grateful to you for your videos. My medical school is a relatively young and small school based in Samoa. We do not have sufficient resources like those well funded and long established medical schools in the industrialised countries. Your teaching videos show many anatomical models with great details. Together with your clear explanations, I have learned a lot from you. Please keep up with your good work.
Hello! I am a physiotherapist but I have not had the good fortune to study on such beautiful models, I really have to thank you for the explanations and the models presented! also now I have a small baby so it's even harder to study 😅😅 thank you so much! (I hope my English is not too bad, I apologize if I made mistakes!)
Great video! I want to hear more about the cerebro-spinal fluids functions. I wish I saw these models when I was in primary school, it makes much more sense then the black and white sketches in the study books. Thank you for giving a fresh perspective about anatomy.
You could use a small table, like a kitchen island with wheels. That way you can manipulate the props with out having to hold them with one hand and showing the details on the other hand. 5 stars. Anatomy rules. A+ best prof.
Interesting discussion. I've been shunt dependent since 2010 - cause IIH or, outdated term Pseudotumor cerebri. I have permanent peripheral vision loss, symptomatic Empty Sella Syndrome and my shunt (that's been replaced or revised 4 times now) ...drains to the pleural space under my right lung, which does not have a large enough surface area for the volume of CSF draining, so I have the joy of chronic pleural effusion. Drainage can't be to peritoneal cavity due to multiple open surgeries, scar tissue and adhesions
Hi Sam, I really love your videos. They have been very useful in my preparation for my Medical Board Part 1 Examinations. I love your entire vibe and teaching technique, I really appreciate those model you have. Just thought to say
This clip is AMAZING! thank you so so so much for posting this! you are a wonderful teacher and enjoyable to watch. Thank you for making a difficult concept easier to understand :)
I've lost expectations of me understanding what teachers say.. i rely mainly on texts... but now i wish textbooks were this simple... i wonder why don't you have a publication of your own.. that'd genuinely be too awesome..
Guys if you are having migraines, post concussion syndrome, depression, anxiety, nuero degenerative disorders, TMJ or back issues check out an upper cervical chiropractor it could very well be blocked CSF flow through the neck.
Great informative video ..Since the CSF turns over 4x daily do you think it would be a waste to inject nutrients or stem cells in the CSF to repair or help brain?
Help please. Heard you saying that the cerebrospinal fluid is made up in the choroid plexus of the lateral and third ventricles, does it mean the choroid plexus of the fourth ventricle isn't capable of producing the cerebrospinal fluid too?
I have been suffering from excess dreams made by humans using electricity for the past 20 years in all the houses I have been living in canada and france. 90% of dreams are man made by electricity. Here are the values on my bed using different meters: The frequency in Hertz of the dreams are around 300Mhz for the high and around 7 hz for the low value. The electric field values on my sleeping bed of each dream range from 40-70 v/m a set of 4 or 5 values before the peak which can be usually around 120 V/m and can go up to 400 V/m if the want to wake you up or shake your heart. Especially if you have excess toxic conductive metals like silver or copper. One symptoms of getting dreams by electricity is itchy ear
I find videos & texts which describe the *boundries* of the ventricles (other brain structures, brain nuclei), and also the *linings* of them (ependymal cells), but aren't there also *structural* aspects to the *walls* of the ventricles? That is, what are the walls of the ventricles *made* of (besides the inside lining)?
@@SamWebster Your midsagittal video is at th-cam.com/video/Njj3DlWX660/w-d-xo.html , but that's not what Nabeelah was asking about, they were asking about the *transverse* sections of the brain, and I can't find your video about those that you mention, although you do show that model with them at 8:23 - 9:23 .
I don't think that would be a problem, would it? I think the number of arachnoid granulations may increase with age, and may have been used (or be used) as a method of ageing a skull as the indentations can be seen in the bone.
I just had a cranial MRI, and one of the findings was some grey matter erroneously in the right lateral ventricle. One ventricle (I don't recall which) was also abnormally large. What effect could they have on me? I'm in my 60s now and haven't had these details mentioned before.
Hello again, soo I was wondering if you could help figure out how I can recognize/ (orientate myself) the levels of the coronal sections since I'll have my Lab exam soon and I'm having very hard time to figure it out. How do I know that specific structures are in a specific coronal section? is there a way to study it better ?
It's very tricky to do this with the brain. It's easy in the thorax because you can take apart a model alongside the MRI sections (if you have them). Really this takes time and a concerted effort of looking at the separate sections and trying to build up the 3D shapes in your mind from the 2D images. This is easier for some people than others. There are some good online radiology resources that might help with this. Good luck!

I can't believe this channel isn't more popular, these explanations are incredibly clear and helpful. Keep doing what you are doing!
exactly
I survived 3 semesters of uni with you're videos! I can't thank you enough!
Thankyou so much! This makes it so much easier to visualize what I’m studying
7:01 3D cast of ventricles
7:10 better close-ups of cast
8:02 another close up
11:00 cast, median & lateral apertures
Medical physiology student in London. this is well explained thanks Dr sam.

thanks for your videos. I am studying to become a massage therapist and your videos help with learning detailed subject of anatomy.
This explanation is absolutely great! Too much information for a beginner but somehow you made it fun and easier
Amazing as usual dr Sam...God bless you for these free videos...
U make us learn anatomy!!
U make it seem clinical, rather than something which is to be boned up!!
You could use a small table, like a kitchen island with wheels.
That way you can manipulate the props with out having to
hold them with one hand and showing the details on the other hand.
5 stars. Anatomy rules. A+ best prof.
Great lecture pal! May god bless your hard work.. thank you

Can't get any better content than there is; on this channel 🤘you rock sir
You hv got amazing models but I suggest to please keep the models steady and focus the camera on the models ...
You are better than a webster dictionary with Dr House together

Thank you dr Sam for this detailed info...
simply amazing man....hats off
I can't believe I finally understand this, thank you so so much! 😭😭😭😭
Love and appreciation from France, also happy new year ✌

Great lecture, thank you sir!
Thank you for this video. Pls can you update the Daily Anatomy app, I'm unable to download it as it is an old version
Thank you so much - great demonstrations

Thank you, really helpful.
These videos are great! Thanks so much!
This model is so good. Waana buy it
Thank you.

I need an explanation of the pyramidal and extra pyramidal tracts please??? I have got to take a test on that ...
Thank you so much 🙏🙏🙏
Good stuff, appreciate it, thank you :)
8:24 I wish if you do an explanation of basal nuclei on this sample sir
Thanks

Is it possible for you to do a video on the transverse sections of the brain?
+Nabz M Yes, we have models that show transverse sections of the brain. I have a video of the midsagittal section of the brain somewhere on here.
@@SamWebster Your midsagittal video is at th-cam.com/video/Njj3DlWX660/w-d-xo.html , but that's not what Nabeelah was asking about, they were asking about the *transverse* sections of the brain, and I can't find your video about those that you mention, although you do show that model with them at 8:23 - 9:23 .
EXCELLENT! Question: What if there is a Arachnoid Granulation in the Transverse Sinus? What affect would that create?
I don't think that would be a problem, would it? I think the number of arachnoid granulations may increase with age, and may have been used (or be used) as a method of ageing a skull as the indentations can be seen in the bone.
great vid !
Thank you!
THAAAAAAANK U SO MUCCCCCCCH
woow amazing explanation i like it
Thank you thank you thank you!

Probably left.
could someone explain this dumb question
So does damage to ventricles result in cerebellum damage which can affect voluntary function?
You are amazing

Does migraine have anything to do with the CSF? Thanks.
Yes it can definitely see a upper cervical chiropractor get your atlas neck bone adjusted to fix blocked CSF flow.
Teacher please talk humble your talking soeed😂I'm not English fluent so understand most but it'll find to make english subtitles if it possible❤
6:57 the cast model
1400 gm brain weighs 25 gm due to buoyancy. Is this true ?
true
That's a beautiful brain. Can you make one for Trump?
It is actually a rare medical condition called the Trump Ventricle. Has only air.
Biden needs one even worse.. just saying.
Can dental trauma damage this mechanism
Zenith bank ad cracked me up 😂
😂😂😂oh hey there
See you
Sam what is impact of hydrocephalus in ventricular 3 and it solve it
V good
2:46 that was sarcasm right? look
Rule of watching sir sam webster's: Drop a like and then start watching.
Sir please provide sub titiles Iam an indian it's really tough to understand your slang
The way you teach is not ok pls learn something from Dr.Nejeeb. l am Dr.Abinet.
Thank you so much
