Neurology | Spinal Cord: Gray Matter Structure & Function

[@NinjaNerdOfficial]

******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!!!

[@rojarj61]

thank you for clarifying it ;) keep up the great work^^

[@NinjaNerdOfficial]

No problem I am sorry for that mistake

[@rojarj61]

@@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?

[@amazuber658]

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.

[@NinjaNerdOfficial]

And this right here ladies and gentlemen, is why we do what we do 🤓 Thank you, much love!!!

[@DrEldersAnatomyChannel]

As a high school anatomy teacher I love watching these videos even though I don’t go nearly as far into depth. Thanks

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❤❤

[@DCYTB]

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!

[@neelamjha7955]

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🥺😍

[@godofallgodswithnoothernam920]

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.

[@thehigherevolutionary]

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. 🙏

[@daninduks6349]

Thanks Zack, you are really wonderful.

[@parisaha]

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.

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.👍
