Blood supply to the brain (circle of Willis)

The anatomy of the blood supply to the brain, including the circle of Willis (or circulus arteriosus). I talk about the vertebral and internal carotid arteries, the basilar artery and the circle of Willis, and mention the cerebral and cerebellar arteries, the blood-brain barrier and the idea of cerebral perfusion pressure.

This guy is awesome! If he was an anatomy teacher near me, I’d retake anatomy just to sit in his class

[@jaimeelliott6154]

it hurts my soul when he seems stressed omg. love ur videos sam x

[@shahrouqari7032]

he looks like Dr house in some parts of the video...or is it just me.😶😶

[@laibarehman3926]

True👍

[@mahwishkhan5466]

He actually does. But he is super cute

[@Diskidiva23]

That's why I clicked on the video lol

[@phallant5919]

Just you

[@mm_nature]

He does remind of house sometimes

[@laibarehman3926]

Thankyou so much sir your's lectures are very helpful..it really motivates me when I'm not able to study or when I feel lack of motivation for study ...

[@adventureclub-beautyexplor5776]

Ohh really?

[@spoon9908]

Hey mate. This has been really helpful for me, enlightening, especially your sit down bit at the end. I had a pterional craniotomy last year to remove an Olfactory Groove Meningioma, and I've coped with symptoms of intracranial pressure episodes of varying degrees ever since. Having a grasp, an appreciation, anatomically on what is going on assists greatly with my coping strategies (especially when medical people I have to deal with seem too scared to or can't be bothered telling me what is going on, like I'm an idiot). Knowledge is power. I'm glad you persevered with making these videos. Your more recent ones are a testament to your learning and perseverance. They're terrific.

[@anevandyk2]

Won’t be attending neuroanatomy lectures any more.. These videos are much better and more informative. Thank you so much!

[@darrylferges4755]

I always loved the clicking sound of the anatomy models. Great lecture

[@gthompson58]

Thank you for this video. September, 2023, I was told that I had a total occlusion of my right internal carotid artery near the bifurcation. I was told I had connecting arteries that would back up the needed blood supply in my brain. You’ve explained those connections.

[@siddhantpradhan1419]

Thanks for making anatomy so interesting.

[@PropheticFate]

Nice

[@rolandparks4318]

Please next time, place a towe under your prompts, so when turned, there is no noise. Is hard to hear what Sam is talking, because of the noise made by the desk.

[@iremserim6517]

[@smilemore1997]

Low key chaotic? He’s definitely chaotic and it’s awesome. As a person. But I wouldn’t want him operating on me or my family and friends.

[@francescait]

when he hits the skull. i feel it . @ 20:13 i felt he is putting finger in my skull

[@mati211p]

13:10 - i felt like hearing Dr. House xd

[@asldkfj1238]

the sliding of materials on the table is unbearable.

[@Theonlybabylara]

honestly

[@smilemore1997]

He does it needlessly dude. You’d think he would’ve practiced this before recording but at times it seems like he doesn’t know what he’s doing. He knows what he’s talking about but doesn’t seem to know what he’s doing.

[@makmotion7156]

I love sam and was gonna say y'all complain about everything but seconds in I see what you mean 😔😔😭

[@Toni_F]

It's like nails on a chalk board! Those models would be better if they had some felt glued to the bottoms. I actually couldn't watch the whole video as it was driving me insane.

[@priyankarane6554]

Why r u so serious

[@ingramjd]

Not even a minute, you had to say the E word. Is there some board of regents or governing body with the power of purse strings that requires we must mention evolution when discussing a topic that is not at all related to speculative fiction or superstition? I reasonable expected to hear descriptive science on this channel.

[@smilemore1997]

Of course anatomy is tied to evolution.

[@dontcallmeFYROM]

Nothing special. Too much "aaaa" to much moving...as in theatre.

[@mqs7547]

Thank you so much sir
