Can someone please write an anatomically correct bone song because college students everywhere need it
I found one! It doesn't have every single one, but it has most of them. Just look up anatomically correct bone song. it's the guy in the red shirt. It's so catchy haha

Hi Hank!!! 8 years since you posted this video. I still follow you today (2023). I am currently following you and I am now a medical doctor. I still use your videos as a solid base when I need to focus research. Thank you for being my modern-day Bill Nye. Lymphoma has nothing on you. Thank you for being one of our great minds.
I don't know about you, but I found Hank's bone jokes to be humerus.
Verroak Krasha bu-dum tsss.
So amazingly humer- wait you already used that pum
+Verroak Kasha you are so punning
+Verroak Krasha HAHAHAHAHAHA!!! XD

Joints
Meeting places between 2+ bones
More joints than bones
Work together to move~muscles contract across joints moving 1 bone towards another
8 cranial 24 facial
Atlas holds head
Cervical 1-7
Thoracic 8-19
Lumbar 20-25
12 ribs
Structural
Fibrous~connect bones with dense fibrous connective tissue~don't move
Cartilaginous~unite bones via cartilage ~don't move ~2 types synchondrodes & symphyses
Synovial articular cartílago , bandlike ligaments, joint cavity, synovial fluid, sensort nerve fibers & blood vessels
Plane, hinge, consular,saddle.pivot, ball and socket.
Gliding movements
Angular movements
~flexion, extension, hyperextensiom, abduction, addiction, circumduction.

A really good way to remember pronation vs. supination is to cup your hand. Supination is when your hand makes a "soup" bowl. (:
That was what we used in school. Supination (Cup hands like you're holding soup) and Pronation (Like you're playing pro basketball)
Great way to remember that, thank you!!
Thank you so muuuuuuch~ it does help!

I'd like to take the time to thank you for making these videos; i am taking college A&P, and I often have trouble understanding the content; however, your videos are clear and fun, and they help me comprehend the content!
I’m in 8th grade am I not supposed to be here?
When I studied anatomy for my animation art course, we are required to be able to draw someone's skeletal and muscular structure just by looking at their photo and during nude model sketch sessions.
Now when I look at people, I tend to x-ray vision them involuntarily.
Remind me never to be in your line of sight.
GuyWithAnAmazingHat When this starts happening, It's useful to try and think about anything else immediately.
GuyWithAnAmazingHat those were my only usefull lessons in art school, tbh...
MegaFarinato I chose animation because it is the most scientific of all arts.
You need to learn anatomy and related biology, psychology, physics, mathematics and programming for CGI animation.
And depending on your projects and specialisation, you may learn engineering, robotics, architecture, fashion, particle, light physics etc.
Animation is about creating a universe with life, so we practically need to know how everything works.
GuyWithAnAmazingHat im working on my demoreel right now =)
I JUST found out that his brother is the guy who wrote "The Fault in our Stars", and my mind is now totally blown...
John Green and Hank Green c:
+Andie Bunker That's why he seems so similar to him!
+Andie Bunker And paper towns
THAT is why he looks so similar to John. I always knew John Green's brother was Hank but I never realized until now omg. No wonder his sense of humor is so nice
oh my gosh really??
"I am so glad you guys are not five years old..."
...as I watch this with my five-year-old. Lol
so he's 8 now?
@@drrush6923 ye
That's embarrassing...I hope you covered his ears 🙉😂
Lol...embarrassing...
Not true🙄
😄This was GREAT! I've been a professional nurse for 40(!)years now & of course learned all the basic A&P of all parts of the human body. As a 60yr old person living in 1 of these human bodies is also another reason for having a Very basic knowledge of the workings of this extremely useful body😊 However, as this thing ages, there are those minor (if we're lucky) "glitches" that occur now & then. When any of these things become annoying for more than a few days, I generally look to refresh my understanding of whatever system needs some upkeep I may be overlooking. This used to be a quick(or not😕) look thru 1 or more of my old nursing books.
But This is GREAT! & FUN! & Moving!-Really moving!, something my old books don't do,except when I drop 'em. So, THANK YOU! For making this all fun again!😀 ...&, as I watched this on my phone, a whole lot easier than those old text books!
Our mid-term exam is fast approaching but I find reading my notes all over again boring. Watching crash course is such a better and interesting way to review. Thank you for this
I'm taking an A&P course online and your videos have helped me go from a C to an A. Thank you so much!! It helps to have images and summary explanations after reading 40+ pages of difficult material. Thank you again!!
So there is a Skeleton inside of me? That is spooky.
Loli21 the skeleton war was weird for all of us.. I know that confusion, hang in there brave one
Loli21 And to the Skeleton, there is a human they are trapped inside.
But it's only when you two learn to overcome your prejudices and work together that the real magic happens. The magic...of Dance! **Techno Beat Fires Up**
doot doot
Loli21 #3spooky5me o_o...
Loli21 But you are just a brain, which is in your skull, so really you are inside your skeleton!
He is good , but lord he speaks so quick.
Turn on the subtitles, I agree
me too.

Ooh Hank and John Green. 2 semesters of AP classes, late night cramming sessions. I still can't pick between you and John. Now I watch you guys for the joy of learning. Feels kind of creepy because I don't have exams but I keep watching the shows.
Thank you so much for doing what you do.
This helps with last minute studying for my A&P exam
i wanted to study biology but ended up crushing this lecturer.ughhh.periodt.
This is perfect timing. In my human body systems class, we need to learn the structures and functions of five systems in the next two weeks because we spent three months on the nervous system at the beginning of the school year. One of the systems we skipped was about bones and joints. Thank you so much for this video, it is a lifesaver.
currently getting me thru anatomy n physiology BIG THUMBS up to this guy! got me thru medical assisting n coding school n now nursing school...ur changing life's bro..thanks
YOU GUYS TEACH ME MORE THAN MY PROFESSORS, I LOVE YOU
Shout out to all the peeps who can actually pick up stuff with their feet ^.^ could do it since i was a toddler.
Hey i'm a nursing student and this was a great way to learn back in my core classes. This can get people interested in medicine or frankly anything to deal with science. Awesome refresher. :)
In this crash course video, I found it very interesting and easy to understand.
- I didn't know that there were more joints in your body than bones, I guess because I never thought about it.
- The way he demonstrated all six different joint movements (plane, hinge, condylar pivot, ball & socket and saddle) made me remember what they all do.
-The reason for why people dislocate that shoulders and hips so often now makes sense.
I'm a student paramedic and I have an exam on the skeletal, nervous, respiratory and cardiovascular system tomorrow. Last minute revision might just pay off with this very useful video
Speedy and impressive. These videos are very to the point with a lack of story, which totally works for study time. They have improved a lot since the first season of their channel.
1:02 He's smoking a JOINT

Thank you! studying hard then watching your videos 2-3 times really helps me keep all of this information in my head! THANKS A MILLION!!
I love all your A&P videos. You bring the content to life and make it amusing to learn. Thank you!
I couldn't even focus I was too busy laughing lmao
HI FIVE
Aaayyyyyyyy....
These videos have been helping me pass anatomy. I love these videos 😂📚📝✏🙌🏼 So helpful!!

bruh
I still remember when poor Hank had to explain things visually by drawing them backwards on a mirror with markers while John had a fully dedicated graphical design and animation team to do that. Go Hank! Haha
Honestly these videos help me so much for A&P . Don’t know what I would do without them ☺️
I wish I had watched this video when I was practising snare drum technique a few years ago. Understanding the movements of the various part of my hands and arms and the associated joints would have helped a lot.
Hank I think you're wonderful! I'm doing an anatomy and physiology online course. I've come to study late in life, and to be honest although I'm thoroughly enjoying learning I am finding it difficult to remember everything. You have made this SO much easier! It clearly is easier to learn stuff when being entertained. Thank you!
Love crash course thank you for making this fun to learn!
I’m a high schooler that binges crash course like most of my peers binge tv shows. What can I say? I like science.
In this video, I learned that synarthroses are joints that don’t move at all while amphiarthroses move only a small amount. An example of an amphiarthrosis is the pubic symphysis that moves slightly to absorb shock. I also learned that diarthroses are fully mobile and are mainly located in the limbs. I then discovered the distinction between the fibrous, cartilaginous and synovial joints. Fibrous joints are connected through fibrous tissue and are mostly immobile. Cartilaginous joints are connected through cartilage and also don’t move very much. Lastly, synovial joints are freely mobile, separated by a fluid-filled cavity and have 6 different, more specific types of joints. These 6 are plane joints, hinge joints, condylar joints, ball and socket joints, saddle joints and pivot joints.
dude.. .cant tell you how many times youre videos have helped me understand such complex concepts and also for things like this! keep it up.
Thank you Hank and the team; you guys are life savers. We really appreciate all your guys' hard work and passion of sharing knowldege...again yhank you so much I love the videos!
I did not realize there was so much more to Joint classification. The Synovial fluid is VERY important, without it your bones could cause enough friction to cook the surrounding tissue. The Synovial Joint has six different configurations which include the phane, hinge, condylar, pivot, ball & socket, and saddle, which was honestly something very interesting to hear about. Before watching this video I did not know the difference between Angular and Rotational movement. Now I know that angular is the motion that increases and decreases the angle between two bones across any plane (flexion, extension, hyper-extension, abduction, adduction, and circumduction are all part of it). Also that Rotational is the motion that turns the bone around on its axis. I had never into consideration that the Ball and Socket joints were so fragile, which now seems to make lots of sense. Thank you Crash Course for making everything so clear to me and helping me put together the puzzle pieces.
How does he manage to be such a dork and so cool at the same time it’s not fair
This video has cleared all my questions. Thanks so much.
I love how at the end of the video it shows what we learned about so we could click on it and go back to a topic to review--Super helpful!
This is genuinely the funniest content I've found on youtube. I didn't come here for laughs, and I find myself laughing out loud. Hands out for you guys, thank you so much!
These videos are saving my life.
I am beyond grateful for these videos. I love to learn
So much great content! Thank you for sharing with us!!
WOW!!!!! You dancing analogy is GENIUS!!!!! What a fabulously practical, relative and memorable way to remember how the joints move/work!!! Excellent!!! THANK YOU!!!! 💃🕺😀👍🏻💙
1:00 was that skeleton smoking a blunt?
MrThingstodotoday A "Joint" to be precise.
MrThingstodotoday He is smoking an articulation.
Alex Nicolae oh my god
lol that was pretty clever !
+MrThingstodotoday ha! and the wild purple star sunglasses from like the 60s?? to contextualize the joint so you know its weed and not a cigarette lmao surprising for an educational group that is educating a lot of children
your jokes and humor destress me while reviewing for my HESI exam, Thank you.
I go from crying while studying to laughing watching these videos. You are the best. Thank you, thank you!!
The dancing analogy made it so much easier to understand!
I've had an odd, involuntary popping like a knuckle crack somewhere near my sternum for a few years and this finally prompted me to look up what it is... didn't know there were joints there! Slightly less disconcerting now that I know that.
I volunteer at my local natural history museum and ever since I watched the documentary "Your Inner Fish", I've told guest about the bones that make up our arms and legs the same way (I.e. One bone, two bones, several little bones). However I use the front arm of a Brachiosaurus to demonstrate the bones.
Absolute masterpiece! Awesome work, thank you!
What! I actually had an exam on this like 10 hours ago. It could have helped soooo much. I love you guys. You do wonderful stuff!
The demos for pronation etc were really useful thanks. I've just got to get all this is my head before my a level pe exam next week
I just love him... He makes learning easy
this would have helped like 2 months ago when i hade to take my skeletal system test you teach it so well
... and I now have one joint fewer than I used. A few weeks ago I had a fusion of my C5 and C6 vertebrae done (blown-out disc repair), so what used to be an intervertebral disc is now bone chips slowly growing together and fusing to take its place, all held together by a metal plate.
As always, outstanding!
Thanks again, Hank and the Crash Course team!
This video is amazing! Good job Patreon Man
i always learn alot from your videos.love em all
this is the episode I've been waiting for!!
Extremely helpful, thank you!
So informative. Really enjoyed it
I'm always thankful, thank you crash course
YOU'RE SIMPLY THE BEST! You basically saved my life haha! Seriously needed this to get all those joints and movements sunk (yes, not stuck -but sunk) in my brain! Bless you! xoxo
From this video I learned the different types of Structural classifications and how too differentiate them, and also how too differentiate the functional classifications
Bloody marvellous!
Thank you very much for thee videos!! Appreciate them so very much
These graphics are so good. I'm impressed!
i like th moving examples of the different types of joints
This Chanel is the reason i got an A on my last A&P exam ily
I loved the bone song! We still sing it in high school, great exercise
this video made my day
you guys are awsome !!!!this video and all other videos helped me a lot.
Omg this guy is amazing! I learn everything by watching only one time. I love you 😻😸
Absolutely live off these videos for exam study, can't thank you enough! :)
Every time the introductory song comes on with that little animation I get really excited for what's to come. I think I've officially become a nerd. Thanks Crash Course.
cueenrlt getting me thru anatomy n physiology BIG THUMBS up to this guy! got me thru medical assisting n coding school n now nursing school...urban changing life's bro..thanks
Don't worry Hank, I rose the roof so high at prom this year
he is too good .
these videos are just awesome!!
n are very easy to understand!!
There isn't a best way to learn than do it with humor. Thank you Teacher😉❤
this was literally so helpful
You made the learning so much fun
Thank you for the video!
Saved my skin thank-you sooooo much !!!!
*giggle* Danced along with Hank while studying for my college-level gross anatomy course. Loved it
I love these videos!
The cartilage that makes up the external portion of your ear (the pinna) is actually neither of those two types of cartilage, but elastic cartilage (at least, that's why I learned in my own anatomy & physiology education). Absolutely love this and all these A&P videos, but the makers may want to edit that note at 0:47!
thank you for the info
This video is amazing
NOBODY! Breaks it down like this guy. Legend 🐐
This video just made my day!
