Peripheral Nervous System: Crash Course Anatomy & Physiology #12

[@CreepypastaHorror]

Honestly wish Hank was my anatomy and physiology professor. I might actually understand it.

[@catholicdoula]

Yeah, me too -- i am taking an online class and she just has us read the book, take quizzes and her quizzes are not easy.

[@sztrebor843]

I have spent months investigating reducing neuropathy at home and found an awesome website at Gabs Neuro Guide (google it if you are interested)

[@LouiseAndria1]

Me too!!! He would be the most amazing professor!!

[@HialeahFlorida]

He has writers. All he has is a very great personality.

[@johnclhugyugihjbvgbkj9729]

Jorge Ramirez I doubt that. I’m sure he knows a lot and contributes. 🙄 and he has the look and speaking-skills and etc.

Best comment.

10/10 made my day

[@lameking2839]

No it was a lego just retextured 😎

[@nizamkhan5060]

hey bro

[@megandcochrane]

Thank you, CrashCourse, for helping me further my education as a 30-something year old. All I remember of science in high school was all the terms we defined. Sadly, there were no discussions or labs - thanks in large part to all the miscreants in my school. However, the ability to learn and understand and apply the knowledge I am gaining from these videos (including the other science videos) and the books I've obtained, I am feeling confident in my pursuit of a medical degree. You guys rock :)

[@i.t9390]

Hope you are still going strong

[@MistressDay]

I'm right there with you! I hope yours still in school or close to graduating!

[@26Mnemonic]

I think it's incredible we live in a world where people are making stuff like this, not only is this more detailed than the stuff I learnt at school, but it presents it in a way that's fun and intuitive, so cool!

[@DArcyBox]

I'm finding these videos amazing for my study, I do university level anatomy a physiology and paramedicine. and sometimes when the content get really intense it's so helpful to take a step back from the insanely hard content do some fun revision of the basics and then try the insanely hard stuff. Thanks crash course.

[@brain_apostrophe_t]

Receptors having those specific names is hilarious to me like sure "thermo" for heat, "chemo" for chemical "mechano" for pressure and "photo" for light make perfect sense but then just "NO!" for pain. The lizard brain named that one 😂😂😂

[@SirRuben]

Some say he's still stepping on that nail...

[@lameking2839]

Late call.....

[@margaridateixeira6333]

I’m studying for my Physiology exam (veterinary medicine) and this channel and Hank talking have been really helping me. Thank you so much

[@malorynramirez1915]

this man helped me understand everything i read while studying for the HESI exam. THANK YOU

[@bassett900]

I wish this guy was my lecturer!! My brain seems to love everything he says!!

[@jacekyle3131]

probably true

[@nuclearwaste002]

"assure your dog you're not yelling at her, you're just yelling" I've had to do this before.

[@etion1999]

The foot bouncing on the needle was sooooooo painful to watch...

[@auregamer5]

Etion Pinaristill not as bad as kzbin.info/www/bejne/aJ6XkmCYoZmUotEm32s

[@Thumbsupurbum]

auregamer5 Oh phew, I was expecting something far worse when I clicked on that.

[@Eric_D_6]

Etion Pinari yeah, that really didn't need to be animated for so long auregamer5 Even though I'd seen it before I ended up watching the entire first sketch

[@ooooneeee]

Etion Pinari Yeah, I had to censor it with my hand to be able to keep watching :(.

[@SherissaDancer]

+Etion Pinari That was extremely painful to me

[@brookebaker9124]

Crash Course, you guys are absolute life savors! I understand everything I watch from these videos! With a terrible teacher who, well, can't teach; these really help me pass his test!!

[@benaaronmusic]

Thank you, Hank Green and all of the Crash Course peoples! Love these educational and entertaining videos.

[@KainYusanagi]

WHY WHY DID YOU HAVE IT ANIMATED TO CONSTANTLY KEEP STEPPING ON IT WHYYYYYYY

[@ahsanarifeen7827]

I'm glad nobody does that in real life

[@happyanyland4627]

hahahaha

[@erica2912]

1:20 Nociception. I'll be using that from now on.

[@NickSheridanVids]

Reflexive actions can be a bitch. A friend of mine was trying to pick something up between two hot stoves. His hand touched the left one, and his reflex told him to pull his hand away- right, into the other one. He bounced between the two at least four or five times before his higher functions made him pull back rather than sideways.

[@NickSheridanVids]

Yeah I know, #CoolStoryBro

[@NickSheridanVids]

+Eugene InLaw It was on a small boat, where the stoves were singular units and built into the architecture of the boat itself. Although he wins no points for sticking his hand down there in the first place..

[@NickSheridanVids]

It was, it really was. Thankfully he scuppered it soon after and lives in a much more modernised, stable boat now.

[@discordant8543]

VidSheridan He should sue

[@theshaunsta]

NickSheridanVids not really a fault of the reflexive nerves but rather a bad placement of those stoves

[@YourDad-dh6fj]

I am Autistic and struggle to feel pain sometimes - when busy, i may not notice stepping on lego, but when overstimulated, my brain overreacts to pain and i feel the stepping on lego greatly.

[@isabellamunoz1099]

This is the best youtube channel ever! This is helping me study for my upcoming physiology exam tomorrow!

[@elizannesmit-inman9698]

Love this channel!! It has made A&P so much easier!! Please do a Pharmacology Series!! Please Please Please

[@reinarene]

crashcourse math subjects would be awesome. thanks.

[@paulafrengul9761]

You are an amazing teacher!

[@lewiscapper-tan369]

These videos are incredible, and make learning biology a real, entertaining, funny breeze. Thanks to all those who produced this video

[@kendramcconnaghy5820]

I never comment on videos but I literally lost it when you described stepping on a tack. Assuring your dog you aren't yelling at her. LOL! Removing the spiney devil from your flesh. HAHAHA! Great videos by the way! You are AMAZING! Can't thank you enough for the much needed jokes while studying. Stay silly CrashCourseGuy!

[@kujmous]

You could say Hank really struck a nerve with this one!

[@lameking2839]

Srysly....

[@lameking2839]

@Razzle Dazzle Did you really get this after 1 yr? You are the chosen one , I have waited for a year now

[@lameking2839]

@Razzle Dazzle Nope your not the chosen one , Sorry kiddo

[@KineSolvang]

Found this chanel a week before my Anatomy exam (This friday!) Thank God for you guys! You made the most confusing and boring class fun and i finally understand the stuff i didnt!

[@melharch3331]

I love learning anat and phys! I didn't get to do any at university despite doing a biology based degree. Thanks for being awesome Crash Course. PS- finally got around to signing up for Patreon, there are some great perks there if you haven't looked into it yet!

[@ElTexMexAlex]

CrashCourse guy is the best!

[@chocolatez9042]

His name is hank

[@ShadowMantis702]

Pain isn't subjective, suffering is. Pain is always sensed, but the proceeding reactions and emotional connections may vary from individual; whether from instinct or conditioning. Naturally speaking: The goal of pain is to entice suffering. The goal of suffering is to entice fear. The goal of fear is to elude death.

[@TheSignetGamer]

ShadowMantis702 Pain is the amount of activated cells mixed with your brain's reaction to said event, the reaction for the brain differs from person to person. Think of it as activated neurons + brain reaction = pain

[@ShadowMantis702]

TheSignetGamer I believe there is a Buddhist saying: "Everyone feels pain, but not everyone suffers." I feel it is more precise to make the distinction between pain (sensation) and suffering (reaction). The signals sent from the nervous system's receptors has already dictated danger, igniting the sensation distinct from fair touch. The following appropriate reaction is to suffer from that feeling. Pain = Damage sensory detection Suffering = Consistent distress to entice the desire for repair To suffer is the default, suffering makes you care about the pain. However this can be different or change. That fact that it can, I think verifies its distinction. Because if they were the same, we'd be condemned to always submit; nor could we discover pain deviants.

[@TheSignetGamer]

true words

[@ShaudaySmith]

Fear leads to Anger. Anger leads to Hate. Hate leads to Suffering. I sense much fear from stepping on that stupid tack.

[@ethanchaney1139]

ShadowMantis702 Thanks for the philosophy lesson. Fr tho, some people do have a higher pain tolerance, all philosophy aside, with what they consider worth being upset about, or in your case you say it’s suffering. If I get hit in the guy I can withstand it, 1. Bc I got used to it 2. Bc of my getting used to that other painful things don’t seem so painful. Yeah some people can deal with it better, pain can be if you take out the distinctions between stuff bc of your own personal philosophy on it.

[@BastieDerSpasti]

Watching these videos makes me painfully aware of my strangeled nerv in my right leg. What is kinda awesome that, if you feed your brain with other random stuff (And painkiller) you can subdue the pain to a degree. But as soon you dive into thinking about it in detail you don`t only feel the pain but can feel it even in more detail as more you know about it. I think that is amazing and baffels me everytime.

[@NecronLordship]

Every time I read one of the titles for this subject, I always think "Aww, no need to be nervous System, everything will be fine."

[@imanmostafamohsein3961]

i adore you CrashCourse team , thanks to all the patreons that make this possible, i will support the show too& Hank i love your way of presenting scintific topics, you re awesome!

[@catholicdoula]

Reflex Arc -- 6:40 -- Thanks for this info.

[@richardincognito495]

Oh my!!! Thank you soooo much for uploading this!!!😭😭 I have a test on this for my ap bio class tomorrow!!!!

[@crashcourse]

Ricky Lin Woo! You're welcome! I hope you rock that exam! -Nicole

[@bluetannery1527]

Did you pass?!

[@JBoyle-jr9wb]

CrashCourse these videos are great when you have an exam coming up, am tired of studying, and want to relax and watch a little tv. Thanks for all the uploads!!! You guys are awesome!!! I too have an exam soon which includes the nervous system. These are very helpful.

[@valerykaravasilev6397]

Ricky Lin Are you searching for the optimal peripheral nerve treatment. If yes, then you should the new drug called Skyarza Neuropathy Treatment Star . I beg you also to search the google for it. Reply ·

[@shannonh1369]

Testing on CNS and PNS next week for online AP class. So glad there is crashcourse to explain it in more detail, instead of just studying class lecture notes in power point. Thank you!

[@YouDontForgetThis]

I am so glad I discovered this channel, these nervous system videos are saving me! Thank you

[@MichAndo2712]

Thanks Crash course, you make A&P very enjoyable and far easier to understand than my dreaded textbooks. Well done to another great vid. :)

[@theblunderkegs2334]

Thanks Crash Course! You make learning awesome :)

[@LexxLazerman]

I love CrashCourse, great job Hank.

[@Gewath]

Animation team working really hard to make you literally feel the pain they're trying to visualize.

[@humanhunter2322147]

[@FlashYourPeaceSigns]

Perfect timing for my exam in two days haha

[@crashcourse]

***** Wooo! Love when that happens :) Happy studying! -Nicole

[@md.abswaruddinfahad8734]

***** I like your video, especially the advice in the second half concerning peripheral treatment. i really like your thought also but i personally recommend Knewreck prevent neuropathy guide for better result . Please Google it for more information

[@CXHo-sy1xz]

Laura Hershel how’d it turn out XD

[@NoahTopper]

I love Hank's hypothetical situations. They remind me of his probability word problems on vlogbrothers.

[@JmSa0615]

i really like your videos.. they're really fun to watch..its nice to have fun and learning at the same time keep it up :)

[@micahperrymoreno]

"...and then you're assuring your dog that you're not yelling at her, you're just yelling" 😂😂😂🤣🤣

[@HolyGround777]

I found this channel today and it is sooooooo freaking helpful!!!!!!!

[@gabrielmiranda327]

Hank. I had a brain hemorrhage 2 yrs ago and your videos help me understand difficult topics and as a result i can make progress and although i may never be "normal" again. You help arm me with information i use in my rehab

[@beau9207]

Binge watching all your videos, thank you so much.

[@achallengedclone9386]

Who would like Crash Course Meteorology?

[@crazysquirrel879]

So sad seeing this seeing a poor guy talking to hi. Self due to his lonnlieness

[@achallengedclone9386]

So sad to see someone who spells hi instead of his....

[@kimoraanderson6378]

Bob Jenkins They also said 'seeing' twice, and "lonnlieness."

[@kimoraanderson6378]

***** If you're looking for an argument, so sorry to disappoint. I have better things to do.

[@sirBrouwer]

for those kinda stuff I would suggest you to take a look at there sister chanel SciShow Space there you will find more likely stuff like Meteorology. It's a cool chanel anyhow.

[@adyanmohammed2067]

I do not know what to do without crash course!!! They life savers ❤

[@sinatarkashvand1010]

your method of teaching is amazing

[@vickiedeng1248]

Thank you for these informative crash courses! Have honestly helped me understand brain behaviour so much better than my actual tutor. Keep up the good work!

[@louisirvinelim]

The animation in this particular video is just. AMAZING.

[@ambylav]

These have helped me so much for exams !!

[@TayTayGrace03]

I love the part about reassuring your dog ahah, so true!

[@aarongreen2119]

you people help me out alot!!!!!! thanks

[@eugenio5774]

I truly love CC... I wish to be an interpreter someday, and I would dearly love to specialize in medical interpretation and cultural mediation. CC helps me to improve my scientific vocabulary to a great extent

[@goofyhayden]

I remember in 6th grade we learned about this and the short name is PNS every time she said that we would laugh

[@yogitabhardwaj490]

we laughed on PNS and ANS ;)

[@tou7331]

LMAO!!!!

[@diegoav974]

I can think of ways how and why...

[@lameking2839]

| 0|0

[@billthewillgates1270]

You were learning about this in 6th grade wtf?

[@choonguanquek4180]

Crash course ,Mr Hank Green, obviously had produced an excellent educational material for our intellectual digestion. By combining what I have learnt elsewhere and the vivid pictorial illustration, it facilitates my learning process. Thanks Mr Hank Green sir, the producer. 🍉🥒🌶🧀🍤🥤🧱🌇🛶🌛🌈🥇

[@lydiabovenkerk4027]

Currently, I am working on my RMT...Crash Course, Hank, has made my studies understandable. Thank you, thank you, THANK YOU!!!

I know this is a completely unrelated topic, but I absolutely cannot wait to see Hank on Tabletop's RPG show this summer. I am so ecstatic to see him along with such a sublime cast. I am eagerly awaiting hearing and seeing his character.

[@BrandonRankin-z6h]

THE BEST THING EVER I LIKE TO SAY IM LOVING THE COURSE

[@TheRooftopSHOUT]

Wow, what a complicated and brilliant design.

[@mseeveemaster254]

what about phantom limb syndrome, or chronic pain after whatever caused the pain is healed, and neuropathy? please do an entire series on what's going on when the body isn't working right!

[@sarahamanda13]

Youu have no idea how helpful this is. Nice work! :D

[@Beanskiiii]

I must enter a sensory deprivation tank. I heard it changes your life lol.

[@mcse404]

[@JBoyle-jr9wb]

Wow, Melissa hope you have days of freedom to catch up on everything. This is one of my favorite channels. I'll go to the biology playlist and end up falling asleep eventually because they play one after another for you. Then I wake up during a completely different subject discussion and realize I was dreaming about the inflammatory response.

[@lopezmeli023]

Yes! I was watching all of the nervous system videos and then I fell asleep and dreampt about glial cells! Lol weird but cool!

[@TheFO12]

This account is awesome keep up the good work!

[@BrandonRankin-z6h]

Thank you, crash course for helping me learn about the world of the physiology of the human body and is really important
