- Hank takes you on a tour of your two-part autonomic nervous system. This episode explains how your sympathetic nervous system and parasympathetic nervous system work together as foils, balancing each other out. Their key anatomical differences - where nerve fibers originate and where their ganglia are located - drive their distinct anatomical functions, making your sympathetic nervous system the "fight or flight" while your parasympathetic nervous system is for "resting and digesting."

When I get through med school, I'm definitely donating to this channel. It has helped me significantly.
Justin Fugate ikr its like I'm actually taking the course, but for free!
200 like....... I did that
Did you donate?
Did you donate?
Justin Fugate hows med school?
Why did it take him 8 minutes to explain what took 2 hours for my professor to explain 😂
Exactly! XD I wasted so much time in class because Crash Course had explained everything so much better. I just ended up watching the videos on my phone and taking notes on them instead.
Because they have to talk about 50 different things along with the main topic
And Hank doesn’t take any time to breath
He doesn't have to explain every single thing 5 different ways for the slower people in the group. They can just watch the video a couple more times.
Professors, doctors are not there to empower us, but rather reinforce their position. Cheers!
Can we all just appreciate that he said "I recognize that this is confusing". When was the last time you heard that from a teacher
Right in time for exams
I have never enjoyed Anatomy and Physiology as much as I do when I watch Crash Course. Hank cracks me up and puts things in such a way that I completely understand it. I actually stopped reading my chapters first, and instead I watch his videos several times first before going through the book. When I read something I don't understand, I watch Crash Course and then completely get it. Crash Course is going to help me graduate in time... and as a single mom and full time student, that's huge. And while I am working my way to graduation.. I am smiling and laughing.. because Hank is literally hilarious. He makes me smile. Thanks Crash Course!
this guy shud have like 20 million views, he is on spot.
Ikr?!😊👍
+Milo curry And its not just him,its the entire Crash Course team! There amazing!!👌😍

I'm in med school right now - and I love you
Elena how is it? :)
I love you more
YESSSIRR!!!!
Hank is underrated people say he is reading a script and while thats quite true the way he presents the data is because he understands it and the analogys he gives is something a bit too good to say he is just acting in reality he is just better than most professors and his glasses and the way he is shows and how he talks is proof enough he was the social nerd that everyone asked for help in school
I just realized you're John Green's brother...wow...these crash courses are really helping!!
Chandreyi Sen yeah they r really an educated family !!!!!!
Anyone else here struggling through Anatomy and Physiology? 😂
MahoGats TFM YESSSS
@@brittneyhansen2623 you've got this!
Nah thx to this channel I’m acing my exams 😂😂😂😭
You should start up a medical school. You teach way better than my teachers there.
CAN U PLEASE???? I'm premed tho but it would still be so helpful. biochem is murder!
Yes please!!!
He is biochemist
heavythinker16 ikr the teachers are like: "today we're gonna learn *insert topic here* and you'll have to take a BUNCH OF NOTES 😵!
I swear!!!
It would be so awesome if you could mention Postural Orthostatic Tachycardia Syndrome (a form of Dysautonomia) or Dysautonomia in general in one of your videos. It needs more awareness and is often found in younger people. Thanks! :)
Like some other commenters I have POTS (a type of dysautonomia) and I can tell you just how important the autonomic nervous system is, because when it doesn't work it feels like your whole body is falling apart!
JUST IN TIME FOR MY NEXT QUIZ! Thanks crash course!
Karen M WOO! YOU'RE WELCOME! HAPPY STUDYING!
-Nicole
I got an 86% on my anatomy test!! Thank you! :D Wish I saw these videos for my first anatomy test (Where I got an 53%) :(
Had a feeling id see some fellow POTSies on here! Keep fighting guys!❤️
I can't tell you how helpful all your videos have been. I always watch the video first before class and it is so much easier to understand what the professor is saying, plus it really helps studying for tests and finals. Thank you crash course! wouldn't be this far in college without you!
I have an autonomic nervouse system disorder, so I love having this wonderful video to help people understand what it means.
This video literally simplified and made this topic so much more understandable than my textbook! Gonna do a lot better on this test because of this! Thank you!!!
Thank you Hank for all the help you've given me in understanding the various subjects you've been covering. This series is a great tool for anyone looking to increase their learning.
Everytime I watch this videos I have a huge smile on my face because these videos are so funny.
Will you explain how disautonomia (?) works? I have POTS (a form of disautonomia) and I don't quite get how it works. Great video as usual!
Same here!
Best video so far ; i was so so so frustated with pre and post ganglionic system
Looking through comments and seeing my POTS family!! Hang in there guys! Dysautonomia doesn't own us!
Wanted to take a second to Thank everyone from crash course for the wonderful videos that help me understand what is going on in Anatomy and physiology
Thank you all
Anatomy and Physiology are topics that just became interesting to me in my mid 20's. This is such a great way to bring information in a creative entertaining manner. Thanks so much for the information, its presented in a manner where I'm laughing and learning. Keep up the great work guys!
I'm currently taking a course to obtain a certificate as a specialist in fitness nutrition and these videos are soooo helpful. love them. have recommended them to all of my peers taking the course as well
I'm actually early! Just want to tell you guys that I absolutely love these videos, and when we watch them in class, I can actually understand you. (my classmates think you talk to fast) I think that it is just great for everyone to watch. So informational! Will donate as soon as I can!
Hank i just wanna thank you so so much for all of this i just love how you teach and how you present, you can't imagine the number of times you helped me understand things academically but more importantly you helped me learn A LOT of things and they stick so easily just cause you put them the way you do. Thanks man
Bruhhhh! I just want to give Hank a hug. I felt like I wasn't going to make it through A&P... but thanks to Hank, I'm doing pretty well. This has helped me SO much!
That was really awesome! The best I've found to date. Textbooks and professors both wear you down on this one every time. It was just a brief superficial overview but the content is wonderfully presented. Thank you so much. great work!!
Hank's videos are almost the only ones I don't have to put on double speed when I'm revising😂 med school lack of time problems
My A&P teacher linked us to this video (and I reminded my peers prior to the exam on this topic), and I have been using this channel's videos since. Informative and memorable, perfect for reviewing information or introducing information.
He's speedy, but I have a pause, rewind, and play button LOL. Seriously my FAVORITE channel. I have already taken API and APII but need refreshing and more detail for my pharmacology course...Hank has helped more than my prior instructors have.
Thank you so much, this video helped me understand what I've been struggling to learn in 1,5 years of medical school and thousands of pages of textbooks.
im pretty sure im undiagonsed ADHD and im struggling to read through lecture slides, so these videos are helping me out a bunch. Thank you guys so much for these videos!
this one was art. really well done. it would have been easy to just state pre and post ganglionic fibers. but he explains WHY it makes sense
These videos help me survive vet school midterms, Thank you crash course!
I'm a yoga instructor. I've been using your videos to fine tune and tweak my anatomy knowledge. Thank you for laying the information out in such a clear and concise manner!! Very helpful!!
I'm doing a biology unit in my psychology degree right now and hank is my saviour here. My grade would be so much lower if the a+p and biology videos didn't exist. Thanks hank!
Love the speed on delivering concepts..
You're the best Hank! Stuff explained by you always sounds easier :3
I have pots (a type of disautonomia) like a few of there other commenters here. A video explaining it would be really cool, because its kind of hard for me to understand!
I agree! I have it too, unfortunately
Me too! How do you guys explain it when other people ask you what it is? I usually explain it as a dysfunction of your fight or flight response, but this backfires when people don't know what the fight or flight response is :/
Mary Elizabeth I usually start by briefly explaining the autonomic nervous system. I say it controls bodily functions that we don't have to think about, like blood pressure, digestion, etc. Then I tell people that my ANS does not function properly, so it tends to mismanage those bodily functions mentioned before. People seem to get it when I break it down like that, but there isn't always time to explain it this thoroughly. I hope it helps though!
I have dysautonomia also I agree it would be nice to have a video about it specifically. However this video was helpful for me because it shows how are ANS is supposed to work when it functions properly. I can just share this video and say this is what is not working in my body. That is Dysautonomia.
Mary Elizabeth I say "we all have a ANS which are like wires that give directions to the body from the brain to do everything. All the stuff your body does without thinking: breathing , your heart beating, digesting ect. And my ANS has a short in it sometimes everything works right the wires pass on the message but more often mine has a disconnect were the message is lost or the wires by themselves pass on a message the brain did not send. And like a short in a electronic device you can never predict when it will short out though one can be aware of conditions that make it more likely to." This is the explanation I have been giving for 12 years it seems to work. Keep in mind though that you never have to tell or explain dysautonomia to people unless you want to don't feel pressured. Also some people might never be able to understand and that's OK.
Thank you! It was easy to understand and easy to remember! 👍
I have an exam today and I understood nothing from my notes so I watched your videos and you could explain in 10 minuets what my professor couldn’t explain in over an hour. Thank you so much
Awesome as usual Hank! Thank you so much for this, you're such a fantastic teacher and so fun!
It seems many of us here have some type of Dysautonomia. I do as well and also have Autonomic Neuropathy. Life is a daily struggle to say the least. Most doctors don't understand and the treatment is nearly void. I was also dx with AAG. Autoimmune Autonomic Ganglionopathy Have had no treatment for this. No drs in my area know anything about it. These video's are great. Thanks for the tid bit on the Ganglia.
It is really aweful when you have to fight your own body daily. ugh... Good luck to all of you here. Well wishes.
you explained sympathetic and parasympathetic so well omg thank youuu👏🏼🙌🏼 Love you’re channel so much!
I'm taking physiological psychology and this helps so much understanding things that we've been talking about in class!
I love Crash Course videos. I'd die for a copy of the Anatomy scripts or a summary. I take notes ridiculously while watching!
I was struggling with this chapter on the nervous system...I have watched all your videos and you guys make it so easy to understand..I'm looking forward to the rest of the videos that cover this chapter and the many more videos you make. I love the song to your intro, I catch my left singing it randomly, is that weird or what? I love the graphics too, the little cells are adorable!!
These topics are in perfect timing for my A2 biology exam in 2 months, revising has never been easier, thank yoooouuuuuu :)
Love your lectures, never boring.
I really hope you will make a video on POTS and Dysautonomia.
I would really like to educate my teachers, family, and friends about this illness that I have. A lot of them either don't understand it or refuse to try to understand it. They don't think it's a real thing, but that's mostly my teachers though.
Please help me spread awareness about this terrible illness. It's been hard trying to explain something that most people don't think exists and you could really help open people's eyes.
Thank you.
win jones The Dysautonomia International website has a place on it where you can get packets for your teachers to explain what dysautonomia and P.O.T.S. is. The website is also a invaluable resource for information.
to take down notes it took me 6 pages of my notebook in 4 minutes!!! Keep up the good work and be the best teacher of EVERYONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)
I'm cramming for my derm/sensory exams in pharmacy school and this is just what I needed! Thank you so much
Definitely recommending to my students. You always help me with my lessons. Two thumbs up!
Crash Course is so helpful. Thank you!
This is a very entertaining breakdown!
JUST IN TIME for my mini quiz !!!
thank you crash course, your anatomy videos is the only reason i understand anything !!! you have no idea how many exams i have done well on because this exists.
THIS WAS SOO GOOD!!LOVED THE WAY THE WHOLE THING WAS PRESENTED!
These videos are so very wonderful!! I wish I'd taken advantage of them during A&P I course but I start A&P II tomorrow afternoon and these are all fabulous refreshers! Certainly helps me find of all the information swimming around up there, just have to dust off the shelves! I look forward to utilizing these videos in my studying this summer as well as in my future classes this fall! Hank! Thanks for being so awesome and making this information even MORE interesting! Keep doing what you guys do! You both rock! :D
Can't believe how helpful this was! Thank You!!❤
Last minute attempt to learn 8 months of a uni course in one night before my exam tomorrow. Luckily, after watching these videos, I'm a lot more confident!
Crash course is why science is the only subject I do not get bored studying for :D
I just started an Anatomy course at a trade school that only meets 4 hours a week. So I was thinking I have a 40 hour work week why don't I just listen to Anatomy stuff all work week?! Well day 1 is almost over and this has been sooo helpful! Thanks CrashCourse team!
Love this channel! Always summarises everything so well. Thank you for making these videos, as I know it is alot :)
Thank you Hank, this episode has been the missing piece of a very big puzzle for me.
Adore this series would love to see more medical series like anatomy or pathology at the AP or university level
I'm prepping for my CRRN testing and these videos are game changers.
Hank, you are the man. LOVE your videos, they are so helpful!
Seriously god bless your heart, that is made of gold ! Saving lives my man
You guys make my Mondays exciting
Crash Course always has the best analogies.
Thank you very much! Very well explained, you are a big role model for me :) Keep up the great work! Greetings from Berlin, Germany.
"Batman calling Alfred up to see how he is after his meningitis"...LOL!!!!!! Oh my gosh! SO flipping funny! I think Hank had a hard time keeping it together at this point. GREAT analogy!
Thank you so much for this, I was having the hardest time understanding the whole thing. You're awesome
I love your sense of humor! thanks for making these videos!
This is great! I nice way to recap all the stuff I forgot because I was slacking at school!
Love the way it was presented. Easy to grasp a complex topic. Great modulation of voice by the presenter kept you focus. Excellent presentation 👌😁
Thank you! Fast, but very helpful. Love the illustrations!
Thanks! This provides excellent information to help me to understand PTSD.
These are great. Thank you so much!
Thank you for making this understandable!!!
I have no words to thank Hank green
Your videos have made med school for me a lot easier. Thank you :)
THIS WAS REALLY HELPFUL THANK YOU SO MUCH. I NEVER COMMENT ON CZcams BUT FELT THE NEED THE TO THIS TIME
super super helpful for my physiology class! thank youuu!!!
I have an exam in 50 minutes... this helped me greatly!
Crash Course has always been awesome!!!!! It makes my lessons easy for me!!
I think professors in general are extremes, some explains everything so slowly like we are dumb and others just presume we know everything, this is so perfect and direct that we understand the hole idea and it gets a lot easier to pick up on the specifics later. thankss btw
I watch lectures in anatomy, come here and slow down the video speed I understand then I go back to watch lectures and understand some more, this channel helps me SOO MUCH
YOU. ARE. AMAZING. so thankful for all these video's!!
Cool episode and neat analogy to think about this stuff.
Love these, especially when uni exams are around the corner and words in text books go blurry!! Hank does an awesome job of narrating, interested to know what his title is or what Degree/s he has got? its pretty phenomonal how we knows so much!
beth from aus!
Thanks for such an amazing channel.. You've seriously got another big supporter...
You are hilarious. And these are super informative, giving a clear overview with easy to understand examples. Thank you.
Thank You so much for this!!! It helped me a lot with my upcoming exam preparations.
Just a slight request, could you do a video about the mechanism of action of lipid-ion-channels, calcium channels, gpcrs, nuclear receptors... etc. that sort of thing?
I am so confuse with those topics!
My professor made it sound so impossible to understand. You don't know how much you've helped me right now. Thank you!
