Sympathetic Nervous System: Crash Course Anatomy & Physiology #14

[@TheInternetcord]

These videos are just so original and professional, so easy to learn from and enjoyable! THANK YOU CRASHCOURSE STAFF!

[@cybertree]

TheInternetcord I agree :D, this was my first episode so I literally discovered CrashCourse 10 minutes ago, and from what I've seen it's the most INTELLIGENTLY ORGANIZED and ENTERTAININGLY DELIVERED science channel I've seen thus far! :)* Seriously, I'm a Registered Nurse and currently pursuing my Biological Sciences degree and this is *TEXTBOOK MATERIAL* taught in an entertaining (and effective) way. *I love how it concentrates on COMMON & IMPORTANT TOPICS* in a very clear way, *especially the RECAP they do at the end*, that's a genius way to drill it into our heads :D, it's like they say, *"tell your audience, and tell them again what you just told them"*

Man it really sucks the body can't tell the difference, I remember going into some exams with my heart racing as if my life was on the line.

[@Xandros999]

aaron Gregor but your body doesn't know anything but your perceptions, so in some sense it's you that can't tell the difference. Your body hasn't a clue about deadlines, fixed expenses or exams. These things do feel urgent, they ARE urgent; it's just that the stress response is badly suited for such complex situations.

[@soup2634]

Xandros999 huh, that's a great point. I'll have to remember that one.

[@DaveMoustache]

aaron Gregor Your life _kinda_ depends on those exams though :P

[@wolfrox777]

True, the body should pump more blood into my brain than my legs

[@Xandros999]

Do the exam hanging upside down!

[@laurasteinemannzimmerman5721]

BLESS YOU HANK. Thank you seriously. This makes SO much more sense. The visuals are GREAT and you really make this so much simplier than the text books. I have been PULLING out my hair and now I feel so much better about this material.

Hi:) Hi! :D *Hey at least your PRODUCTIVELY WASTING your time :P.* Which sounds like an oxymoron but in actuality your simply getting recognition for the homework.

[@xoRaQxo]

Mine uses the series and include a video in each lesson. Brilliance lol

You might even say, *click*, stressful. This is why we love you Hank. Thanks to you and all your colleagues for making these videos. I cannot express my level of gratitude in words. :)

My trick to remembering" Beta Receptors" is "Be Relaxed" 😅

[@xJUHz]

18 years old and had my first burnout from all the stress. Id have to say it was not a fun experience, but i learned alot, i feel somewhat grown up and know how to get things done. No more stress cancer. I am steady as a rock.

[@xJUHz]

DurexDurpaneu2 yeh, i felt like i learned more than ive ever had in school. ive never been sadistic to others kids or something ;) But now i believe even more in the strenght of positive energy and myself as one :)

[@oussamael7150]

JuhaniP I'm 18 too and have recently had the same experience (burnout), i even took a semester off of uni. so tell me: -How much time did the recovery take -How bad was it -What "trick" did you use to overcome it, if any -Any tips?

[@X3fishyX3]

+Oussama El I know I'm not the same person who you asked the question to but I also experienced stress burn out (also 18 at uni!).. I reached a point where the stress became so much I just shut down and wasn't functioning in any aspects of my life... I was getting to the point of making myself quite seriously ill both mentally and physically (not eating etc...)! One thing that helped me was realizing that my self-expectations were way too high and that I was beating myself up over things that I shouldn't be e.g. I felt I wasn't doing enough work, when in reality I was! This is partly due to the fact I had a hard time getting onto the course and was determined to not mess it up (which incidentally I was on the path to doing with the amount of pressure I was putting myself under!!) My parents forced me to take a step back and look at what I already know vs what I think I should know and suddenly life seemed a bit clearer... Instead of focusing on how bad I felt stress wise I channeled my thoughts into positive thoughts for other people e.g. if someone was dressed nice I would tell them! I have done 4 assessments and have passed them all and although I still get stressed, I have learnt to take a step back and remove myself from it! Also exercises and showers when it got too much helped me massively! ;) Hope this helps xx

[@whatrtheodds]

Burnout is terrible, mine happened when I was long out of home, it took my body ages to recover. I was all alone and had no support. But alas lesson learnt, it took me a good 9months to recover, my body would just shut down, it was in pain, fatigue was an everyday occurrence and i got depression very heavily. I found it so so hard to work and study and do anything, but I didn't stop I just slowwwed right the f""" down, I found that really challenging as it made me feel somewhat pathetic, I judged myself so harshly. I learned a few things like even though I want to set myself up, I need to have fun, have limits, be kind to myself and it okay to need TLC im only human and maybe even if I try my best I still may not get to my dreams and that its NEVER worth the burn out.

[@aramisfarias5316]

This episode was really great! I could completly follow the pace and learn stuff. Thanks Crash Course Team. You people are great.

[@madisoncampbell151]

Thanks for the video Hank! Can you talk more about adrenaline/nor adrenaline and muscarinic receoptors? And the different subtypes eg. alpha 1 and 2 and beta 1 and 2

[@weirdocentric23]

I needed this video sooo much, my body is in constant stress mode all kinda things going on and for the life of me couldn't explain why. Now I know my system is all out whack I need to find a way to balance it all, It all makes sooo much sense now. Thanks a million🙌🏾🙌🏾👏🏾👏🏾👏🏾👏🏾🙏🏾☮💜

[@Sophi023]

I think I've seen these videos at least 20x, no joke, I'm on a waiting list for nursing school and don't wanna forget anything. I took A&P back in 2016 when these came out. So thankful!

Wow, These videos are SO helpful! Thank you SO Much for making these! I really can't thank you enough. The professor that teaches the course I am in is terribly confusing and has a language barrier. Its very hard to understand her. The book and notes only help so much but these videos and online flash cards have been the Most helpful! Honestly I don't know where I would be without these resources! Thank you so much! (: You help my parasympathetic system feel so much better! My sympathetic needs to stop over reacting!!

This was a very interesting episode. I really appreciate all the hard work y'all do educating us on anatomy and physiology because I really think it's relevant and important for people to know about this kind of stuff. Keep 'em coming!

[@jcarloscortezv]

HI Hank! Do a show about the language (history, neurolinguistics and etimology)

[@marinar1380]

Yes please!

[@AnstonMusic]

juan carlos Cortez I sort of think that would be more of a John's domain. Perhaps Hank would chime in at neuronal and biological factors, though. ;) Have a nice day!

I mean it’s crash course for a reason, to be quick. You can slow it down if u look for the button somewhere on ur screen.

Note: Norepinephrine is NOT the only neurotransmitter released from the postganglionic neurons of the sympathetic nervous system. Acetylcholine is released at sweat glands and epinephrine is released at other sites.
