Big Guns: The Muscular System - CrashCourse Biology #31

[@Spectolect]

Major kudos to Amber, the head of graphics. A visual learner like me cannot thank her enough!

[@brbrerolling]

I'm in the same place!

[@Amandakaymtz]

how did people 20 years ago even pass their classes without youtube channels like this one?

[@sabey5126]

I've been researching into human anatomy and discovered a fantastic resource at Anatomy Blueprint Pro (check it out on google)

[@lalalalalala7849]

Amanda Martinez they cut up bodies for research

[@unitechtherapyy1453]

they actually studied, maybe?

[@arjanharjani3109]

I was able to learn about all the muscles and bones and everything else through pure reinforcement and practicing with my classmates- our books did not even have much color but we used our imagination and used the cadavers and ourselves to keep ahead of the curve. Med school was fun because we chose to be excited about what we learned and not pressured because of grades!

[@gingergiggles]

God, this is so much easier than listening to a robot voice explain this. You make studying for my exams way more fun, dude.

[@triciareneetlcprofitness7045]

I totally agree!

[@tamaraherman7073]

First of all, thank you so much. Second of all, for those who think he is talking too fast, you can go to your viewing settings and lower the speed- not only is it slower, but it's slightly hilarious.

[@hptruefan]

omg thanks xD

[@ovemesojude7445]

hw pls?

[@najeyrifai1134]

How it feels to watch Crash Course while stoned.

[@daaaniphantom]

Tamara Rostro I tried it. HAHAHAHA thank you so much for bringing this to my attention

[@danielwong2395]

😁🤣🤣🤣🤣LOL

[@crashcourse]

we are attempting to cover the topics that would be taught in a year long AP level Biology class, equivalent to a 101 level in a college or university. so it will be more complex than general high school biology.

[@louisthedonothing69]

You should write a book

[@joet5342]

Always astounded at how Hank and the team make science, especially complex anatomical functions, so accessible, when so many mind numbing videos on the internet bang on for hours with complex 'shit' for want of a better word. Of course science isn't 'easy', there'd be no fun if it were no challenge, but these people give you all the jargon and all the action without all the boredom. Great show.

[@SuzDove]

Joe T So true indeed!!! I am loving the challenge, Hank and the team really make it FUN!!

[@crashcourse]

Thanks. The animations for Biology are actually created entirely by our Creative Director, Amber Bushnell, with the help of a consulting biologist, Brandon Jackson. Thought Bubble does the animations for World History exclusively.

[@julianewberry5468]

I have been struggling to understand this for over a week, and you managed to explain it clearly in 12 minutes. Well done. Very well done.

[@homeiswonderland]

Cramming for an in class paper I have to write on this tomorrow. Finally understanding it! Thank you so much!

[@aniridhbakshi]

My uni prof made this WAY more complicated YOU ROCK!

[@davelangford2439]

Probably the best CC video I've watched. Hank actually spoke at a normal speed!!

[@flubbycat1724]

It's amazing how all the little parts (both visible and microscopic) inside of you are a big deal on helping you function and live against things outside the body or to adapt the body to the environment.

[@clarecohen399]

I really want to thank you for these videos. Without you I would be lost in my anatomy class. You're the reason I'm getting an A in my class. Not only do you clarify everything for me but you make learning FUN and enjoyable. PLEASE KEEP MAKING VIDEOS!!!

[@michel4743]

Two small questions: - Do you workout a little or not at all? - If you don't workout: How much did your arm hurt the next days from all those curl reps?

[@sarahk6926]

LOL ikr I thought he was going to stop much earlier!

[@TheSkullcrusher73]

Pretty sure that weight is probably nothing for him.

[@crystalsdynamicwellness8239]

this video saved my life!!! trying to understand the myosin and actin filaments from my text book made me want to cry and jump off a bridge in tandem!!! Now I totes get it thanks to the schnazzy sliding filament model! Thank you snarky smart guy... you are my hero!

[@maurco007]

He forgot to mention that muscles are antagonistics. Therefore, if one contracts the other one relaxed. So ATP IS REQUIRED ALWAYS

[@nalenenlal]

Thank you

[@Zizzyyzz]

I doubt he "forgot". Lol.

[@nydiahernandez2127]

you teach me WAAAAAAYYYYYY better than my science teacher!!

[@knoxc4248]

man that comment was 6 yrs ago... how di that turn out?

[@defydog]

I learnt about this when I was doing a course to become a fitness instructor. I remember taking several lessons to learn less about the process than you taught in under 15 minutes. Thankyou

[@boredoutofmymindize]

My IB biology teacher used this video in class. So much more helpful than all those stuffy old videos from the late 90s with boring voice overs on lame animations. I actually learned a lot. Thank you so much for making these.

[@PeninsulaPaintingProjects]

You're crazy but you're a lot better than my tutor so thank you.

[@Omisslewis1976]

I used his videos in my classes b/c I love them, he makes it fun!

[@amber854]

This channel is an absolute life save. I've an ISA on muscles tomorrow and I've been trying to get my head around the topic for days with no luck. I rewatched this a few times and then made notes as I went along, and finally its making sense! All is not lost! so THANK YOUUUUU!!!!!

[@SavourySnape]

So you managed to explain basic sliding filament theory in the space of 12 minutes from the beginning, while being absolutely engaging and funny at the same time? Better than any lecturer with any amount of experience that I've seen...

[@andy4an]

Hank, your presentation is much less annoying than the original episodes. I am glad because I enjoy your content.

[@randomtrucks]

Wait, our muscle filaments need ATP in order to relax? WHOOoooaaahhhhhhhhhhhhhhh that's why dead bodies are stiff cool

[@AnuRMusicVideos]

WOAH I never realised that!!!!!!

[@TechWeLove]

I feel that all Anatomy Courses should have tons of videos like this, but also focused at helping students pass practicals, and exams. Find professors who put their lectures into video presentations. That will help a ton.

[@Brownzz07]

Hank, you da real MVP!

[@toinfinityandpandas1372]

You have no idea how appreciative I am of this channel. It's helped me go through A&P, Microbio, Bio l and now finally...bio ll 😂 you guys are a godsend

[@danielpetracci3826]

This was so helpful! What would I do without Crash Course?

[@roohullahbukhari1557]

I never learned physiology in the class from proffessor who used to to teach us... it's u man who helped me master it....

[@CaliGirlFromKZ]

I am SO grateful for this and for other crash course bio videos!

[@Snagrit]

After the first 4 videos of Crash course Biology I had a new hobby which led to me enrolling in an introductory Biology course as an elective to my degree. 6 Months on, and I am now studying a double degree (Arts/Science) With majors In history, Biology and Psychology. In high-school I hated science, but I can honestly say thanks to you a passion has been ignited inside of me and I know look forward to many years of studying this fantastic subject that YOU introduced me too. Thanks.

[@Orangemocha4]

Learned more here than in my class - plus the guy was really cute.

[@JoeAuerbach]

One of my favorites lately. This is one of the best things that happens in the body. Totally fascinating.

[@heatherstubbs5466]

Great video! Easy to understand! I need more of these videos to get me through A&P!

[@Abominatrix650]

I've had 2 lectures on this so far and I've understood more with this video than I did in those lectures. But in all fairness, the lectures didn't have pause and rewind features and this video doesn't require me to get up early and have minimal breakfast to attend!

[@putrisha94]

Here for my anatomy test. Thank God for CrashCourse cuz I didn't understand shit from that lecture >.

[@christinewithak7903]

I think these descriptions are amazing, so easy to understand for a "mature age" and previously uneducated student. Thank you.

[@legitfacts6731]

Moral of the video, if you want a genius son then just name him Huxley :D

[@rondanicolay7493]

I showed this to my massage students it really helped them so much..thanks for making learning about muscles fun !!

[@waynetrinklein5938]

I did the same! Really fun stuff :)

[@786shabz789]

U forgot sarcrolemme and sarcoplasm and the h,m,a and z zones ( I think it's just my a level course that I need to remember all this stuff damn there's too many sarcro

[@reno2934]

786shabz789 Theres 3 sarco things (atleast in level 1 bio which I assume your in), not that many :p

[@isardiv08]

You're not the only one! I just love life and learning amazing things.

[@BittiKit]

Thank you so much. Anatomy was confusing me so much a few minutes ago, and this is definitely helping me to better understand the material.

[@rachaelrausch8023]

ME TOO! This was like heaven 😂😂

[@user-qm4lk7lm9o]

soooo much better than 3 hour long power points followed by 3 hour long robotic voiced videos where I retain absolutely nothing

[@guchichan]

This makes A&P fun to learn!!! Haha ☺️

[@sincitycapital]

Congratulations you're in AP want a cookie?

[@heatherstubbs5466]

Steven it's not AP it's A&P..... they are not the same.

[@sincitycapital]

That's nice

"Like middle school students at a formal dance," Haha perfect.

[@thebride910]

Wow that was so good. Thank you for dumbing it down for me and explaining it simply in a language that I could understand. If only all teachers talked and explained this way.

@thought bubble

[@shilpakaran1]

Hank! your ass grab...spot on!

[@RodeyMcG]

It is so impressive how much you covered in 12 minutes, and how well you covered it! It took me at least of week of lectures to understand that before.. You even managed to cover rigor mortis! Nice!

[@greg77389]

Where did Hank find that stunt double to work out for him?

I'm really glad you videotape these. It makes it possible for me to repeat parts of your lecture I miss because I find myself concentrating on moving my muscles and thinking about what happens under the skin cover.

[@randomnerdfairy]

i did most of my revision for my gcse biology with Crashcourse and i managed to get an A* on my first exam so thank you hank

[@ApertureScience27]

I swear Hank is reading my mind. I was just reading about this on Wikipedia a few days ago. I was having a bit of trouble understanding, so thank you Hank for helping me out.

[@aykayjk]

Why can't Hank be my teacher??? My school has 2 anatomy teachers but I got the sucky one and tomorrow it's my final and he didn't help anything.

[@NuUnlimited]

Hank would be the best teacher EVAHHHHH!

[@NeonsStyleHD]

Why don't you show this video to your teacher, he might learn how to teach better, and thus be a better teacher and that means you will like him more and therefore you will learn more and enjoy to classes more. Don't however tell him he sux as a teacher as that will assuredly get you bad grades!.

[@ruddypaulino5694]

1 month in 13 mins. Thanks man. You're saving grades every day!

Anu R When I was younger (4 or 5) I used to think there was a certain part of an animals body that was the meat we eat. Man was I stupid

[@peppusae]

Gosh, thanks so much, Hank! c: I have an exam tomorrow and I was really frustrated about not knowing a single thing! XD So I found this really useful, so much preach for you! ♥

[@justinweng3849]

"pent up frustration" "groping" this dude is really thirsty amirite lmao

[@patplayz7752]

I just wanna get rid of school and I can’t thank you enough for helping me getting rid of my worst nightmare.

[@Tibialisanterior]

I never understand the bits where he talks about ATP and ADP Please can someone explain like im 5 aha. 😭😭😭 Anywaysss GREAT VIDEEOOOOO!!!!

[@crow4834]

ATP broken down is ADP and a phosphate

[@crow4834]

When the third phosphate is removed from ATP, you get ADP. The molecule has much less chemical energy, because the high energy bond between the last 2 phosphates has been broken.

[@micopico09]

I totally brushed up on my muscle physiology with the video before giving a lecture. That's right: GIVING one. Also, totally used the middle school formal dance analogy. Thanks, Hank et al!

[@KurdishFalconPKK]

Pause at 0:01 for the fright of your life.

[@sterellabobella]

Wow, this is really interesting. I never would have thought it was that complex. Our bodies are truly amazing, I found myself pondering my hand's movement throughout the video. Keep up the great videos!

[@indra4325]

i have a serious crush on Hank, like can i marry you??!? haha

[@LouanneDalBello]

Love this video! Takes my hours of studying for Exercise Physiology and condenses it into 13 minutes.

[@ryanashburn7831]

Subscribed! I just want to say wow. I'm working on my Personal Training Certification With The American Council on Exercise and all though I understood all of this before watching I want to say thanks for making it so simple for simpler minds like my own lol. You guys rock and I look forward to watching more!

Super good!!! This is great because I'm in art school and I kinda miss my science classes from community college. I like being able to understand a little more about how bodies work. Pretty awesome!! Thanks so much for making these.

[@mstapleton49]

your videos are so amazing. they help me understand all the major concepts I need in A&P to pass exams. plus, you're pretty hilarious. THANK YOU!

[@instormental]

It's amazing how despite all the electricity and chemistry needed to activate a muscle, when I want to move whatever body part, it seems to do so instantly, and despite how many different muscles a movement requires, it usually works with awesome synchronization (i.e. the way we just wish we could make robots move but somehow you can always tell a robotic movement from a natural one).

[@preisser32750]

Hank... I may be old enough to be your mom.. but as a nursing student... I am in love with your adorable nerdy persona... your the best.

[@jonettekruk3156]

Thank you so much for your videos. They are so much help! I like the way you compare processes of the body with other scenarios.

[@WCOBDisorder]

Everything is complex. Even the simplest parts. It's amazing.

[@amakachinwe5711]

Where were you guys my freshman year of college?!? You guys are amazing! Thanks!
