******CORRECTION***** at 32:31 I stated that the preganglionic parasympathetic motor neurons that occupy the interomediomedial nucleus at S2-S4 supply cardiac muscle. THAT COULD NOT BE MORE WRONG!! I must have had a huge brain fart when I wrote that!!! Very sorry Ninja Nerds!!! TO CLARIFY!!! Cardiac muscle is ONLY supplied by preganglionic motor neurons of the sympathetic nervous system from T1-T5 spinal Cord level and the Vagus nerve which is Cranial Nerve X is the parasympathetic supply to the cardiac muscle. SO to end it all off, S2-S4 preganglionic motor neurons which occupy the Interomediomedial Nucleus ONLY supply Smooth muscle and Glands!!! Alright Ninja Nerds sorry again!!! Hope this makes sense and clears up any confusion!!!
thank you for clarifying it ;) keep up the great work^^
No problem I am sorry for that mistake
@@NinjaNerdOfficial dont say that... ninja nerds dont do mistakes, ninja nerds do happy accidents ;)
Love that!!
Please tell me the ans,
The following items are related to each other in a hierarchical fashion: chromosome, base pair, nucleosome,kilobase pair, intron, gene, exon, chromatin, codon, nucleotide, promoter. What are these relationships?
Zach. I just wanted you to know, you are simply an amazing man. To make all these videos for free, to educate people who arent able to pay for tuition fees, and to keep on posting videos with that enthusiasm, I salute you. Please never doubt yourself and never feel discouraged. I managed to pass in my exams because of you. I began to understand more about the human anatomy because of your dedication in posting these videos.
And this right here ladies and gentlemen, is why we do what we do 🤓 Thank you, much love!!!

Thank you sir
As a high school anatomy teacher I love watching these videos even though I don’t go nearly as far into depth. Thanks
I'm not studying this yet but every time you upload a video I just drop a like so I won't forget once I study from it
I cant suport you guys with money but each time you guys upload Im going to drop a like. Keep up the goos work
Watch every ad without skipping any. That's how you help them out!
@@sameeha5380 noted
They don't need ur money babe
Yeah me too. I dont skip ad and I give like right away😍
I am going to share these videos to as many students as possible...because you have been a life saviour for we medicos in these tough times...🤩🤩....truly speaking I literally have been binge watching your playlists...thank you Zach for being there🥺😍
Zach I just wanna give you a hug, man 😂 You guys have helped me for so many years; all throughout college and now med school! One day I'll be able to contribute financially but I promise I'm sharing this channel with as many students as possible! Thank you!
simply awesome, straight forward, nice for repetiition as well, as you give time to answer before resolving, clearly structured, detailed enough without overloading. You are an inspiration.
Simply awesome!
Man everything is coming together so neatly.
Notice the playlist organises eacb segment which eloraborates and builds on the next one, like a tangible body of information to step upon akin to solid ground.
The explanations are so indepth, with about 30 notepads and a few pens, you can copy everything a few times over and learn an entire university course worth tens of thousands of pounds or dollars in your own local library or bed room.
I just think this man is amazing, to rember this amount of specilised knowledge then explanatorily communicate it so the mere mortal humans such as ourselves can innerstand this speckalised knowledge.
unbelievable! just when I started studying neuranatomy in med school your videos popped up and helped me so much.THANK YOU A LOT , i am sure that you help a lot of us who search for help
All I can say is WOW.
I would hope more learn to teach like this. Clear, concise and clarity.
Thank you
I think I m gonna thank you in my thesis.
You seriously did more than my professors in these years🙏
Thanks for another SC lecture. Love ninja nerd science! Dr.Zach you are an absolutely awesome teacher. Love your mind and skills. Keep helping students worldwide👍 Looking forward to spinal cord lesion video.
I don't know if i'll have all the time to watch those vdos before exams but surely I'm absolutely going to watch all of em later cause they're just amazingly exhaustive ❣️
It's the best channel for those who have lost the base for any topic like its been taught yrs ago but here this man will really help u...like so much... Can't thank enough❤❤
As a nursing student, you are absolutely saving my ass in anatomy and physiology. I thank you for your noble work
Thank God for your lives, Ninja Nerds! Our Neurology course in medical school is so much EASIER because of you. Much love from the Philippines!
I can cry over this BEAUTIFUL video🤤...Man UR AMAZING...I adore you for your easy peasy lectures made of MOST difficult lessons!!!!
I've never hit the like button that hard in my life. Thank you!
If I had a neuroanatomy teacher like you, I'd have been a trained neursurgeon since the age of 6.
Immensely proud to learn the you explain here in books it’s so confusing and complicated!! feelings confident 👍🏻
Regarding the gray matter and tracts,the best explanation i have ever had...thanks a lot Zach...
I used to call myself an anatomy buff, but my knowledge of the CNS stopped at cerebral landmarks and nuclei, and large nerve plexus and bundle groups - the spine has always been a blackhole of knowledge for me and spinal cord features feel like a whole new world to explore. 🤯 Wow, this was a great vid - I'm glad I joined your patreon. 🙏
I am like 😍 when i receive a notification from ur utube channel u r absolutely the best
Thank you so much Zach for your knowledge and awesome skills in teaching!!! One day, when i become a doctor, i’ll be forever grateful for your videos. I love you ninja nerd!!! ❤️ Keep doing what you do coz you’re so awesomely fucking good at it. 😘
Im so grateful for these videoes. I really wished my teachers were like you. Thank you NinjaNerd
Thank you Zach. You are gift from the heavens.
Been studying these playlists for my neurology residency entry exam next week. Thank you Ninja Nerd for the amazing and detailed explanation. Wish me luck guys :)
Good Luck! You've got this! - TG
U r such a great inspiration to me sir my dream is to see u atleast once in my life time btw excellent video I understood it easily
Your lectures have been very useful to me..i really want you to post more on pathology and microbiology
amazingly explained! it can't get any better. thank you for your hard work
I have started ur biochemistry lectures it's absolutely easy to catch the idea.
Thank u so much SiR❤
Happy teachers Day to you🥰 I got my concepts clear by you 😭❤️ Thnku so much for your informative lectures❤️ I owe my success to you🥺❤️without you I am nothing💕
Thank you so much Zach ! You are an amazing tutor ! You are great, you are the best. One of your many fans here, in Bulgaria, in Sofia University
Thank you so much for such lectures... It literally saves our time.
It was very difficult for me to learn this topic ..so I always hated this...I was never able to fully understand it.But now thanks to you for the first time I got to understand everything and it's not difficult anymore.Now I find this topic interesting. Thanks a lot 🙏
I cannot like this video enough! Thank you, thank you, thank you! Does supporting your channel count as an educational expense according to the Dept. of Ed? 😅 You honestly deserve the money more than my school/lecturers because I learn so much better from your youtube lectures than their Zoom lectures.
Really informative and concise, thanks ❤️
Holy wow.. this is very comprehensive and well-summarized
Thanks a lot 👍👍
You are awesome to the core. I love your videos. Keep the good lectures going!
"boom roasted"
You explain all this way better then my son’s neurologist! Thank you 😊
Special thanks for your kind illustrations of those hard topics we are struggling with all times 😅
Not currently studying anatomy but gonna have to do this in coming months but still wanna support the channel,so playing this video on all my devices
And that is how i got blessing from ninja nerd for becoming a good doctor 🙏🏼🙏🏼🙏🏼🙏🏼
Thank you sir for sharing these kinds of videos for medical students!

DIVE IN DEEP, god bless you for these
Love u sir out standing lectures and very kind and happy sir ❤❤
You always make my days easy
You are amazing Ninja Nerd.
Love from India
what a talent, just genius, keep it up
Absolutely enjoy your videos
Great video covered more detail than my anatomy book
Great video, but I just have one question. So, if the Lamina 6 has the cell bodies for the Ventral Spinocerebellar Tract and the Clarke's Nucleus has the cell bodies for the Dorsal Spinal Cerebellar Tract, what kind of proprioceptive information goes to the Nucleus Proprius more specifically?
The grey matter also extends from the brain into the spinal cord. The grey matter creates a hornlike structure throughout the inside of the spinal cord while the white matter makes up the surrounding sections of the spinal cord. The grey matter does extend to the spinal cord to make signaling more effective.👍
Beautiful... thank you for making this video you are so much better than my professor 😂
- medical student from South Korea
Looking good, Zach!!! Keep up the good work and thanks for the video!!
