Major kudos to Amber, the head of graphics. A visual learner like me cannot thank her enough!
I'm in the same place!
how did people 20 years ago even pass their classes without youtube channels like this one?
I've been researching into human anatomy and discovered a fantastic resource at Anatomy Blueprint Pro (check it out on google)

Amanda Martinez they cut up bodies for research
they actually studied, maybe?
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!
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.
You should write a book
God, this is so much easier than listening to a robot voice explain this. You make studying for my exams way more fun, dude.
Emma Galindo lol
I totally agree!
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.
omg thanks xD
hw pls?
How it feels to watch Crash Course while stoned.
Tamara Rostro I tried it. HAHAHAHA thank you so much for bringing this to my attention
😁🤣🤣🤣🤣LOL
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.
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.
Joe T So true indeed!!! I am loving the challenge, Hank and the team really make it FUN!!
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?
LOL ikr I thought he was going to stop much earlier!
Pretty sure that weight is probably nothing for him.
He forgot to mention that muscles are antagonistics. Therefore, if one contracts the other one relaxed. So ATP IS REQUIRED ALWAYS
Thank you
I doubt he "forgot". Lol.
I can't thank you enough for this, this is the future of education. Education should not cost 100k with the internet. Free education for all!
Cramming for an in class paper I have to write on this tomorrow. Finally understanding it! Thank you so much!
You're crazy but you're a lot better than my tutor so thank you.
I used his videos in my classes b/c I love them, he makes it fun!
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.
My uni prof made this WAY more complicated
YOU ROCK!
you teach me WAAAAAAYYYYYY better than my science teacher!!
man that comment was 6 yrs ago... how di that turn out?
I got it! I got it! After hours and hours of reading, I HAVE GOT IT! THANK YOU!
gotta love you guys, thank you for putting all this content together into an amazingly understandable way.
Probably the best CC video I've watched. Hank actually spoke at a normal speed!!
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.
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!!!!!
"One of the sexiest things that happen in your body...other than sex"
We watch this in school
@@izzyschell721 Omg, yea
Time Mark?

@@jazzram_ Thank You.
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!
Thank you SOO much for doing these videos! You've made learning this information so much better. Keep up the hard work.
Great work! I really love how much help these videos can be.
I am SO grateful for this and for other crash course bio videos!
Great video! Easy to understand! I need more of these videos to get me through A&P!
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.
One of my favorites lately. This is one of the best things that happens in the body. Totally fascinating.
Wait, our muscle filaments need ATP in order to relax?
WHOOoooaaahhhhhhhhhhhhhhh that's why dead bodies are stiff
cool
WOAH I never realised that!!!!!!
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!!!
Crash Course is so helpful and entertaining! It provides such a great framework for learning and review. Hank, you're brilliant and hilarious. Thank you.
This just blew my mind! love these crash course videos. Lifesavers!
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...
Moral of the video, if you want a genius son then just name him Huxley :D
Thank you Hank! :) you're the best, the visuals really help me a lot!
Great overview - and so hilarious. I simply enjoy having fun to understand all the events at the neuromuscular junction. Thank you so much!! :-)
Who else studying for their bio exam
Hank, you da real MVP!
Thank you so much for this awesome episode!!! And the result that I got was also fantastic! The first time I got 100% in my Biology assessment!!! Thanks again for crash course!!! Keep on doing it!!!
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
This was so helpful! What would I do without Crash Course?
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
786shabz789 Theres 3 sarco things (atleast in level 1 bio which I assume your in), not that many :p
Hank, as usual, a really great tutorial. Simple, FUNNY and really interesting. Thank you!
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!
Learned more here than in my class - plus the guy was really cute.
Here for my anatomy test. Thank God for CrashCourse cuz I didn't understand shit from that lecture >.
Amazing videos guys. Watched a lot of them now and they are all very good at getting the info across.
Studying to be a personal trainer and doing hnd level fitness. Again, great videos :)
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!
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.
ME TOO! This was like heaven 😂😂
Hank and his hot pockets....
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!
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.
Hank! your ass grab...spot on!
This makes A&P fun to learn!!! Haha ☺️
Congratulations you're in AP want a cookie?
Steven it's not AP it's A&P..... they are not the same.
That's nice
ok, you're funny, you get a pass
+Steven someones salty
You've mastered communicating potentially difficult stuff. Really helps me prepare and review. ty ty ty!
Amazing presentation amigo. The illustrations are very helpful as well. Keep up the awesome work.
1:32 I'm dying hahaha
+Dani elle :D
ikr..
"Like middle school students at a formal dance," Haha perfect.
Just so very well explained and entertaining. Thanks guys!
Found this (or should I say re-found this) just in time for my exam this week! And thanks to Hank it makes more sense than my A&P teacher ever could. Granted there was some stuff left out (A band, I band, Ach to name a few) but it makes so much more sense now!
ATP in the Hisoooouse!!!!!!
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.
Hank would be the best teacher EVAHHHHH!
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!.
Brilliant Hank! You've once again made the subject less complex and prevented me from tearing my hair out!
Thank you!!!! so much, You are such a life saver. Best video I have seen entertaining and very easy to understand. Love it
I UNDERSTAND MUSCLES NOW
Where did Hank find that stunt double to work out for him?
greg77389 Assassin's Creed
this is so helpful. the animation makes it very clear. thank you crash course
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.
"pent up frustration" "groping" this dude is really thirsty amirite lmao
I like to eat muscle fascicles 🍗🍖
I will never look at a steak the same way again.
I mean...what did you think steak was?
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
You guys are awesome! Thanks for all of the videos! They help a lot:)
I think these descriptions are amazing, so easy to understand for a "mature age" and previously uneducated student. Thank you.
i have a serious crush on Hank, like can i marry you??!? haha
The best way gain muscle mass fast there Gain Weight-F
+Bernardo Grosse I understand this program is only for man?
+Bernardo Grosse This man knows what he is talking
+Bernardo Grosse it's incredible
I think I love him 😂 he’s so funny and also saving my life this semester
OMG...
... This is a GREAT Video/Tutorial...
Love it!!!
I never understand the bits where he talks about ATP and ADP
Please can someone explain like im 5 aha. 😭😭😭
Anywaysss GREAT VIDEEOOOOO!!!!
ATP broken down is ADP and a phosphate
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.
Pause at 0:01 for the fright of your life.
ahahhaaa i laughed out loud at the "tapers off at each endon to a tendon" goodness thank you for making my bio homework 100% better
So helpful. Thank you for doing these videos.
nursing school entrance exam 90/90 here i come
Who is watching this during corona crisis?
Great video, simplified it well for me to understand perfectly
Thank you :D the animations really help
amazing, love CrashCourse, make my medicine simple...Thanks Doc
This is magically helpful. Thank you Hank!!
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!
I'm using your videos to study for the MCAT! Thank you for having the different body systems!
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
Thanks for making this one! It's very helpful.
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.
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.
I have a test on muscles this saturday and this video potentially saved my grades. Thank you so very much, Hank! Great timing!
This guy is brilliant and hilarious! really adds a fun dimension to learning, bravo & thankyou
ohhh goshhhh....i m luving it.....ur way of explanation is justt awsome......thnx hank!!!
I always get so hyped when that Little Big Planet style music comes on !!!!!! Thanks Hank for making Biology awesome :)
you're awesome! thanks for making THIS interesting!!
hank, you have no idea how much these videos have helped me i'm on my way to becoming a nurse and these have helped my study tremendously!!! thank you so so so much!! DFTBA :)
Thank you for this video its really help me understand Muscle Relaxation
love him he has helped me more then you know-thank you
