You explain stuff so much better than overpaid college instructors. I have been trudging through a Brazilian rain forest book and hours of lectures and notes, and you say in 16 minutes what I am unable to get out of 2 hours of lecture and 2 hours of reading. Please keep this up, please expand your method, please show the world how to teach people like us... or all people... because it works. Thank you, I know I will get at least 3 questions right on this upcoming anatomy exam.
i can't tell if i'm more impressed with his ability to draw on a powerpoint presentation, or his excellent description of the skeletal muscle. Much appreciated video with great explanations!
whoever this dude is teaching in this video, hes the man! EVery video he teach is awesome and soooo easy to understand! PLease keep it up, you are the reason I am understanding everything in my human biology class!
I am a massage instructor, and teaching the sliding filament theory in A&P was really difficult for me the first time I did it. Getting ready to teach this again, and am thrilled I found this video (and your other ones) - nothing I have seen (and last year I was looking everywhere) comes close to this video as far as clarity and completeness. This is just excellent, and I thank you for posting it!
Thanks a lot, again, i'm in a nurse school ( i'm a guy don't get too excited ) and your lessons are really helping me understanding biological things. You're a born teacher, keep this up you rock !
My classes are 50 min. long, 3 days a week. You just familiarized me with a unit we worked on for over a week which by the end of it I was completely lost. Its like professors don't want to take the time to teach you because college is traditionally looked at as spending time out of the class room studying. The point of education is to make "learning" occur, and you do that incredibly well.
I didn't expect you to cover anatomy and physiology and I almost cried when I found this one!! Thank you for your awesome work!! I don't know how many As I've got thanks to your videos.
Loved this video!!! My professor is about teaching the "concept" but look at TH-cam for lectures!! I don't understand it either, but text books can be so dry with material and i am a visual learner, So THANK YOU for posting this!!! breaking it down the way you did really helped
this video saved my life. i dont understand anything in my anatomy honor's class, but it's nearing winter break which means grades are due. the least i can do is score a C on my test before i leave. i finally understand everything that my teacher tried to teach us in 11 days. thank u so much
Thank you so much for all of your lectures online. I just spent 3 hrs going from one video to the next. I am taking an online course so it's hard when you don't hear someone talk or write on a chalkboard. Your slow speech, clear explanations and incredible art talent, I am learning so much that my intense, super difficult book tried. Thank you soooo much for being born :)
Excellent. To draw everything - to see it step by step becoming... better than one picture at once and than explaining it. Pictures at once are distracting. Keep on going.
quick clarification, at 11:03 when Sal draws the I-band, the way he has it drawn the I-band should go from the A-band of the first sarcomere, all the way to the A-band of the NEXT sarcomere. I'm sure Sal knows this but just to clarify. this came from my A&P text book
As an artist and A&P enthusiast who’s been watching Khan Academy for years now, I can’t believe I’m just realizing his drawing skills! I’m delightfully impressed 👏👏👏
I work out and Im a legal guy by education. You are amazing and make complex functions easy to understand. This is better than a movie and is so interesting.
I like how he ends this video by saying "I hope you found that mildly useful" Obviously an understatement, i feel like i know pretty much everything one needs to know about muscles in an A&P class, im not going to class.
I LOVE your videos. you are very good at explaining how things work and I have depended on your videos so much through my entire biology class. They have helped me pass with honors!!
Best Videos Ever. Very clear and easy to understand. You know your subject by heart and , that is why you can teach so clearly. Thank you so so much for posting your videos.
My girlfriend sent me this video because she had to study for an exam. I'm a graphic design student and I found this video interesting and educational enough that I stayed for the whole video. Probably not useful to me, but very intriguing. :)
O.M.G I M SO GLAD THAT I SUBSCRIBED TO KHANACADEMY AND YOU R REALLY WORTH PRAISE WELL I DONT PRAISE ANYONE BUT YOU R JUST WORTH................. SIR U R MY BIOLOGY PROFESSORS NOW LIKE EM FROM SOUTH-ASIA PAKISTAAN IN SINDH HYDERABAD IN SUPERIOR COLLEGE OF SCIENCE AND U DID GOT THINGS IN MY MIND WAT MY MA'AM DIDN'T LIKE YOU ROCK U TUBE................. MAN................ LIKE ITS A GOOD DAY DAY TO ME...............12-10-2010 :) ;)
Thank you so much!! my anatomy lecturer just sent us an archaic video on skeletal muscle and I came searching hoping you had a better one!! You've saved me a lot of brain ache!!!
Wow this is so clear! Do you have a video about how muscles grow? Like what happen to the tissues, cells and the other parts of a muscle when the muscle is growing?
Are there several neurological connective points throughout a strain of muscle consisisting of many muscle cells or is one electric signal from one axiom enough to contract the whole strain of muscle (from one end of skeletal attachment to the other)? Simply put: is it possible to contract a partical segment of a muscle more than another segment down the line.
Could you upload a tissue differentiation video? Alternately, feel free to redirect me to a video that gives a comprehensive description of the process of tissue differentiation, thanks.

kay I agree♥️♥️♥️
It’s the khan academy guy! He created it 🤩
Such a great video. Why can't my teachers be so clear when they teach?
exactly
I was just thinking this!
YOUR ARE BETTER THAN MY ANTOMY TEACHER

The videos from Khan Academy are just so amazing!! I'm learning more from the videos than I would be from a 3 hr lecture...

Quite possibly the easiest explanation a 20 page chapter in a textbook cant give. THANK YOU!!
I wish I could like this video a million times. Thank you so much!

"Hopefully you found that mildly useful." No, this basically saved me hours of studying and deciphering my teacher's powerpoint!
"MILDLY useful"? that was the most interesting, the most helpful and the most lucid explanation on muscles I've seen!
I think it's funny how he say "i hope you've found this mildly useful" at the end. THIS IS INCREDIBLY USEFUL AND EXTREMELY HELPFUL. Thank you

If I pass the MCAT, you will be the reason why. Thank you so much for all your videos
Used Khan during undergrad and once again, during graduate school. Thank you!!!!
So well explained with all colors which is making it easier. Thnkx a lot!
I like how he ends this video by saying "I hope you found that mildly useful" Obviously an understatement, i feel like i know pretty much everything one needs to know about muscles in an A&P class, im not going to class.
"mildly useful" video?
HUGELY useful!
In the college even the doctor said that I know no one understands what I’m talking about, but you in 16 minutes made it clear ♥️
I LOVE your videos. you are very good at explaining how things work and I have depended on your videos so much through my entire biology class. They have helped me pass with honors!!
its truly amazing how you can sum up 6 hours of lecture 3 days a week into just over 16minutes, and yes I'm quite serous.
Super! this video is better than my lecture in class. Thanks for posting, really helps!
Best Videos Ever. Very clear and easy to understand. You know your subject by heart and , that is why you can teach so clearly. Thank you so so much for posting your videos.
I didn’t find this mildly useful but very useful.Thanks for sharing your knowledge on this in a much clearer way.
Idk what I would do without you
My girlfriend sent me this video because she had to study for an exam. I'm a graphic design student and I found this video interesting and educational enough that I stayed for the whole video. Probably not useful to me, but very intriguing. :)
Thank you so much, I'm doing a medical degree and it's brilliant the way you go from simple to complex explanations.
congrats now
O.M.G I M SO GLAD THAT I SUBSCRIBED TO KHANACADEMY AND YOU R REALLY WORTH PRAISE WELL I DONT PRAISE ANYONE BUT YOU R JUST WORTH................. SIR U R MY BIOLOGY PROFESSORS NOW LIKE EM FROM SOUTH-ASIA PAKISTAAN IN SINDH HYDERABAD IN SUPERIOR COLLEGE OF SCIENCE AND U DID GOT THINGS IN MY MIND WAT MY MA'AM DIDN'T LIKE YOU ROCK U TUBE.................

:) ;)
Simply a wonderful accurate presentation for students and a good review for doctors as well.
Thank you so much!! my anatomy lecturer just sent us an archaic video on skeletal muscle and I came searching hoping you had a better one!! You've saved me a lot of brain ache!!!
Wow...BEAUTIFUL drawings!!! Better than the ones in my A&P book!!
This guy has the best videos out of all. I listen for his voice then I know it will be good 😌
Bro, how can you excel in every stuff, U are a genius!
out of words. Thanks for all the work you are doing.
This guy is my new hero.
OMG!!!
I spend an hour scrambling through my anatomy textbook trying to understand this
when this 16 minute video is SO much easier to understand lol
Amazing job explaining this. Can not imagine there are some people with thumps down to this video.
This is so amazing! For a a first year medical student this is amazingly helpful! Thank you :)
I'm Dutch and even though this is in English, it's clearer for me than when my teacher explains it !!
Thank you, you just helped me pass my exercise science test.
Great video I am so glad my professor recommended it for us. So simple yet so full of information.
Fantastic video! Absolutely helpful and simplified so it's very easy to understand. Thank you Khan Academy 👌👍
i completely agree with underxman u deserve a nobel prize
also u helped me learn the meaning of a true genius=)
This is for what youtube is really helpful!
lol I love the pun at the end "I hope you found that mildly ("myo"ly) useful" :DD
u r an angel, sal i wish my teacher taught this stuff like u do
thx ur awesome =)
Damn you are good at drawing and your teaching...........EXCEPTIONAL
I finally have an idea of what is going on in my Anatomy class, I wished that I watched u since the beginning of the semester
yes it was "mildly useful"
you deserve more
Excellent video! have one question though.
what kind of drawing programme do you use?
I was reading my A&P textbook about this and did not understand how the function works. So then I remembered Sal and searched for this video. thanks!
Wow this is so clear! Do you have a video about how muscles grow? Like what happen to the tissues, cells and the other parts of a muscle when the muscle is growing?
do you have any of these videos on smooth muscle and cardiac muscle??
OMG!! this video just saved me from going bonkers!! thank you khan academy!!
A comprehensive tutorial on the anatomy of a muscle cell by Salman Khan.
this... is.. more than mildly useful... definitely more than that.
Excellent, thanks !!!!!! excuse me.. how do you do to draw while you are making the class??
thanks a ton! really helped me understand a muscle cell compared to my bio textbook. Great drawings!
I have mine in August. Do you think that his videos will be thorough enough or not too helpful?
Man you're great...my MCAT topic is all cleared out ❤️❤️❤️❤️
nucleuses = nuclei
just a helpful tip. Love your videos
So when the muscle contracts, do the I-bands still have no myosin? Or does the I-band size keep changing?
u made my life.... thnks for posting this video....
mildly useful?! This taught me more than my teacher did!
You rock that was an awesome video it saved my project
Thanks Sal. You are incredible!!!!!!
Are there several neurological connective points throughout a strain of muscle consisisting of many muscle cells or is one electric signal from one axiom enough to contract the whole strain of muscle (from one end of skeletal attachment to the other)?
Simply put: is it possible to contract a partical segment of a muscle more than another segment down the line.
so easy to understand.. awesome thank u.
Thank you soo much, this video help me in my understand anatomy and physiology clas
You sir are a great man.
Awesome teaching dude!
Wonderful. Great description thank you.
Amazingly helpful.
"let the crawling begin!" lol i dunno why but this had me cracking up...
OMG!!! I get it now. Thats so awesome. Thank you soooo much!!
You're a real hero!
Great video, Really helpful
OMG this helps on my project sooooooooooooo much
thank you!!!!!!!!!!!
thanks for your tutoring! very helpful!
u r so awesome! u make me stick to my majorrrr!!! bio whoop whoopppp!!!
"mildly useful"???
that was great! thank you so much!
This was so helpful, thank you!
Could you upload a tissue differentiation video? Alternately, feel free to redirect me to a video that gives a comprehensive description of the process of tissue differentiation, thanks.
This is excellent!
Awesome video! Thanks
Thank you for you amazing videos. I am also a teacher. What format/program are you using for these videos? Connie
Does anyone else know?
I really appreciate that
thanks lot
I wish my teachers would teach us like this
What are the previous two videos?
SUPER DUPER AMAZING !! thank youuuu.
awesome, thank you so much for explaining it so well
