Neurology | Sympathetic Nervous System 

CORRECTION AT 6:14 The sympathetic nervous system doesn't cause contraction of the ciliaris. It actually relaxes the ciliaris which tightens the zonules causing the lens to become more flat, which is important for far vision. Sorry for that mistake ninja nerds!!!

I’ve been teaching medical students & residents for the last 30 years at Columbia Presbyterian Hospital in New York, so I have seen the crème de la crème - but you sir, I have to say, are A+++. Thank you for your clear and concise presentations which I recommend often to my students.

His enthusiasm and excitability to teach makes him a different breed of educator

DUDE! You are a scientific angel sent from above. THANK YOU SO MUCH!

This guy's a legend.....literal epitome of humbleness and patience sprinkled with the efforts and hardwork ....love your smile ....keep growing...❤️

I’m in med school and I learned more from your videos than reading my books hahahahaha

This is so comprehensive yet extremely engaging at the same time. Incredible!

Can’t resist of comment on this , wow your lectures are amazing, and I have never learned specially neuroanatomy like this before these videos are very much clear and very much understandable and very much logical; thank u so much🙏♥️

Best anatomy and physiology teacher on youtube. I wish you were my professor. I will tell my classmates about your channel.

Im a Police Officer and we learn an overall of this stuff in a DRE program (Drug Recognition Evaluation) but this is really more of what I want to know. More in depth.

You are awesome!! One request: for future videos can you take a shot of the whiteboard after you have finished the lesson? I think it can be very usful. Thank you again!!

Zach, you are the absolute BEST!!!!!! Thank you for this and all of your videos.

Best medical teacher thanxxxx a lot

Your videos are great, man. Please do one on Limbic System and Structure/connections of Hippocampus.

These videos cannot receive enough praise. Fantastic stuff

First year master's student here. I can't believe that I just found this RU-vid channel. The presentation of this content is amazing and perhaps more in depth than my textbook!

Thank you, I couldn't understand it from the books, but you made it so interesting and organized. You're awesome!

Thanks a lot , much better than my professors. I recommended your videos to all my friends ❤

This is just so clear and well explained! I can't thank you enough.

Thank you so much. You are the main reason I did well in Anatomy and now your videos are helping me in Physio. I get so excited when I find videos you have made on the subject we are learning because it starts to make sense! Thank you so so so much! I wish my professors taught my classes like you.

because you focus in one system , you're capable of being informative and you've the key of the watchers mind

You are one of the best teachers on youtube .... i feel enlightened after every one of your videos !!!

Thank you so much for this! I'm in Med school and your videos honestly save me for Medical Physiology!!! You're amazing!

Mennnn. I got more from this video than 4 Hours of Nursing Anatomy. God bless you bro. Keep on Recording

This is one the channels that should be introduced to students. The diagrams and processes are very well explained. I personally like the explaination which was made easy for me to understand.

Man, you are too good !! The humor you put into this video made it more interesting . Those plexuses always confused me, now they have started to make sense . Thanks, to your hardwork !! Keep it up 😊

I had Scheuermann's disease as a teen and when it developed, I began having a fast heart rate, sweating, anxiety, Raynaud's/acrocyanosis,flushing/blushing, and orthostatic weirdness and erratic energy levels. The docs thought I had a pheochromocytoma, but that was negative. Adderall actually helps. I had my spine corrected in 2011 and look and feel awesome.. I workout a lot and built a lot of muscle... But my sympathetic nervous system is still super super super sensitive. Metanephrines and other adrenals are all normal. I am completely convinced there is something related between my thoracic spine (my curve apex was T8) and my sympathetic nervous system overaction. 20 years since diagnosis, I finally found a health care team who says I am not crazy. It's likely not going to kill me... But I'll tell you, it can be very frustrating. There is basically no known medical studies involving what I'm conviced of (idiopathic scoliosis/kyphosis related to hypersensitive SNS), I'm basically on my own LOL. Great video.

god bless you! after 10 years of being far, you did an amazing job in renewing what I need to refresh! amazing!

Wow I did not know for switching receptors in uterus im so glad that listening to your videos i always learn something more than just the topic that you're doing! You are amazing.

I am a APRN planning to return for a post masters certificate in pysch/mental health. In preparation for this, I have turned to lectures to review the nervous system and other related basic A/P. I really enjoy this lecturer. He is very knowledgeable and his teachings are reliable. He identifies ambiguities as he notes them in the textbooks accordingly which I respect. He is very enthusiastic and I am glad I found him. I wonder what he is up to these days. Nonetheless, thank you for sharing your knowledge.

This helped me a lot, thank you professor. I'm from Brazil and love your videos.

i dont know how to thank you again zack but ur videos are so awsome they save the pain to go to the texts most times and its very very helpful when i prepare for my anatomy exams thanks a lot i get to understand a lot of things instead of just blindly reading the texts thank you again . this makes anatomy much better
