OMG literally the best neuroanat videos on the internet u just explain each and every corner of it from the beginning that just brings no doubt!! AMAZING
you are like a guardian angel omg i cant tank you enough
I really appreciate your video. It gave me a complete idea of the ventricular system and its relation with cranial nerves within a short time. Hope to get more from you.
I passed my exam today thanks for the helpful videos ❤️
still watching because anatomy is always needed!
Heyy congrats!! Glad i could contribute to your knowledge 😄 all the best man 💪🏽
Amazing video per usual!!! Also, please do you have one on the other ventricles of the brain?
thank you for providing such quality content for free. the animation is so helpful in visualizing the structures 💛
Happy to hear! 😊
It's super helpful. Thank You for your work ❤️❤️❤️
Excellent videos with animation. Thank you!
I addicted to your video ,Everytime before the lessons I'm making notes from your videos,its help me lot,thank you❤️really appreciated your effort👌

God bless you brother. Wish you the best
Thank You for your work
Great video! Thank you!
absolutely lifesaver
شكرا تيم.. أنت رائع جدا.. ❤
U are a legend!!
My dream has always been to become a neurologist, but I could not get a degree in medicine, this does not prevent me from learning everything about my passion and why in my profession as a future physiotherapist I may not need much.
Really happy I could contribute to your learning! 😊 And I'm super impressed that you're learning about the CNS by your own will!
Sorry to hear that you didn't get a place in medicine, but I'm glad you've found an alternative passion to pursue! I barely got into medicine, so I get your standpoint 💪🏽🌟
I am a physiotherapy student myself and we have the entire neuroanatomy in first year with the rest of anatomy as well (all limbs, thorax, abdomen, pelvis and head&neck) in third year we have Neurology and medicine along with its allied subjects also surgery including neurosurgery.
edit: also the allied subjects of surgery.
Thank you 😭
You are a Godsend!
Taim,ur the best
Thank you so much
really good.
that table at the end is helpful
Nice one
Make more like this
Amazing
Thank u so much
omg thanks
thank uu🥰
i am the luckiest one in my friends
how you don't have 1 million subscribers !❤
We slowly getting there brotha 🙏🏽
Not everyone's in the health care field to find these gems
Great ❤
HEY! Great video!
P.S. Small error in description of cochlear nuclei.
Wat u do
does anybody know the difference between *lamina tectoria ventriculi quarti* and *fossa cerebelli transversa*
what are those exactly
i have no fucking clue i am sorry but i wish the best for you and your descendants

THE ACCESSORY TEACHER😁😁😁
👍👍
👍👍👍
Hello dear doctor, When and how can I pass the anatomy to you!?
I like to help you 🥲, I could pass two year anatomy with high degree by reading and consistency I wasn’t care if I fail in daily activity but I never left reading and I told to my self I can’t do it but I always say to my self (people before me pass why I not ) so you can do it too
❤
👍💐💕🌹

I want to tell you that Jesus Christ loves you all and He sees you. Jesus Christ is the only way to Heaven. He will be coming back soon "Jesus coming back soon" is not a myth it's actually true, please let's get ready for His coming, He is coming to take His children that obey Him to Heaven, a better place, He doesn't want us to go to hell. Read Romans 10: 9-17 in the Bible you can check it online, ask God to come into your heart, ask Him to forgive you of your sins, help you never to go back to them and He should make place you on the right paths in your life tell Him He will put it in other for you anything you want, tell it to Him He will answer you,ask this of God in the name of Jesus Christ and end your prayer with, AMEN(meaning so shall it be).If you prayed this prayer you are now a child of God. 🥳🎊 .He cares about you.
Thank you😊.
beeeeeeeeast
