Autonomic Nervous System: Crash Course Anatomy & Physiology #13

Рет қаралды 3,029,536

Күн бұрын

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."

Why did it take him 8 minutes to explain what took 2 hours for my professor to explain 😂

@arynsinger6811 5 жыл бұрын

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.

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.

@kathryncoogan4987 7 жыл бұрын

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!

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 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.

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.
