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!!!

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.

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

[janice]

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❤❤

[godofallgodswithnoothernam]

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.

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!

[neelamjha]

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🥺😍

[fionabickerstaff]

As a nursing student, you are absolutely saving my ass in anatomy and physiology. I thank you for your noble work

[andrealeonti]

If I had a neuroanatomy teacher like you, I'd have been a trained neursurgeon since the age of 6.

[gurla]

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 ❣️

[jamesgordon]

All I can say is WOW.
I would hope more learn to teach like this. Clear, concise and clarity.
Thank you

[legendlegend]

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

[xxy]

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!

[Nosnosiii]

I can cry over this BEAUTIFUL video🤤...Man UR AMAZING...I adore you for your easy peasy lectures made of MOST difficult lessons!!!!

[zarrkez]

Im so grateful for these videoes. I really wished my teachers were like you. Thank you NinjaNerd

[marcelovilasboas]

I cant suport you guys with money but each time you guys upload Im going to drop a like. Keep up the goos work

[vodkashots]

Regarding the gray matter and tracts, the best explanation i have ever had...thanks a lot Zach...

[dochala]

I am like 😍 when i receive a notification from ur utube channel u r absolutely the best

[obedbagona]

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!
