The cytoskeleton | Structure of a cell | Biology | Khan Academy

Courses on Khan Academy are always 100% free. Start practicing-and saving your progress-now: www.khanacadem...
Exploring the cell cytoskeleton, including microfilaments and microtubules (with a brief mention of intermediate filaments).
Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

The reason khan academy is amazing is because it appreciates scientific concepts and phenomena as something to be appreciated and marvelled at, not mugged up

[@adelasefora]

I agree!

[@lradmclovin9]

God I love Khan Academy

It is nice to know that Bernie is interested in this topic. After hearing this topic you appreciate your body and your health. Teaching people to maintain our health is very important, Check out www.PromotingHealthyCommunities.com. See: Surgeon General: " The economy doesn't do anything without a healthy work force", Bernie can have a HUGE VOICE in improving our health care system. May God bless you as your continue to serve our citizens

Chickabeast a very convincingly cogent and well thought out argument

Mr Sanders, its a pleasure to see you enjoy learning medicine. Im a first year medical student in a caribbean medical school. I was raised in Cuba, where most of my family members are physicians themselves. Where people have absolutely no access no medical supplies, medications, xrays, where my aunt died from there being no doctors to see her in an emergency, where my uncle went blind from there being no electricity to have the operating room available for ocular emergencies..these r the routine cases in Cuba..where there is "free medicine". Socialism/communism is the saddest, most diabolical system humanity has practiced..believe me..i have read Carlos Marx etc..i only wish it would actually work..u are either profoundly ignorant, naive, or simply..a hippocrite. May God bless you 🙏

I love this presenter! You have the best voice/gifted gab for videos not making me fall asleep :-)

[@dalia9512]

Holly Beri you should check out his physics ones; he's a life-saver :')

[@adelasefora]

Khan Academy is my go-to every semester that I have biology because no teacher explains it this well!

[@CellRus]

Actin and cancer migration and metastasis is what Im studying for my PhD! :D Amazing movement of the cells, you have to see them live to appreciate the sheer dynamic of the cells and all the ruffles and protrusions, woven around.

[@Pbmarron]

Khan Academy has saved my butt more times than I can count. It helped me re-learn all the math and science I had forgotten when I decided to go back to school.

[@ym.9862]

You saved me! My textbook made no sense and you explained everything in 6 mins, Khan Academy you’re awesome!

[@radusoldan1340]

I always have on question. Is the cell structure predetermined like our body ... (we have an exact location for liver, hearth, lungs, arms etc) or is random determined by molecular entropy ? Are the organelles position, number encoded predetermined or random ?

[@Sage_ping]

maybe like microtubules in cells, something holds the organs in the exact place in every human being ,we just haven't discovered it yet ,maybe sometime in the future the answer will be clear

[@Marisol3069]

Very creative way of showing this painting to teach about how complex our cells really are. Fascinating!

[@samuelgreenrod1812]

Unbelievable I had to wait until the first year of a Biology degree to find out the cytoskeleton even existed. A level Biology is rubbish

[@lfdoidao]

In Brazil,we learn about cytosqueleton in high school, and overall about the cell in quite some depth. However most of it fells like dry and useless. Knowledge uncontextualized

[@joshboston2323]

Khan academy might actually be the most awesome thing ever in the world..

[@thequickestway1329]

i am chemistry study.but i have to study zoology in 2 semester in last days i think i am not able to pass this subject. khan academy help me alots i love khan academy keep do this work you guys are really great.

[@AnonnymouZ]

i done learned me some cell structure today son! err, i mean. Thanks for the lesson! :D

[@shahdnabah8124]

your voice is so soothing

[@Jose-tx1yx]

Are you sure the cytoskeleton filament you highlighted is the microfilament? The peach colored filaments look more like microfilament to me. The one you highlighted looks more like the intermediate filament.

[@sammansour4374]

thin peach-colored are actin filaments, the darkest one is an intermediate filament, and the thick light blue is microfilaments

[@Dagreton]

more videos on cytoskeleton, please

[@deoklingz__06]

this is so cool, cell is amazing, thank you for your explanation!!

[@Rana-ke9bp]

goddamn this is mesmerizing

[@shewanabeysinghe291]

khan academy is so valuable to everyone

[@johntindell9591]

thank you very much.

[@tonyc6163]

You are fascinating with all these videos this is alot of help. Are you receiving your phd? And if so in what?

[@s0gier90a]

Apparently, he doesn't have a Ph.D., but he did obtain his Bs and Ms degree at Massashutes Institute of Technology (MIT), which is considered to be the best university on earth ;)

[@dilipprakash2990]

Awesome explanation. *suggestion: use "Pen" instead of "arrow" mark in mouse pointer.

[@izpotter]

Could you give a link to the image you use in the video?

[@sheyla13sm]

So all cells have myosin. Would it be Myosin I? and actin?

[@dralokmisra]

v informative

[@waleedparas1120]

What about Intermediate filaments?

[@adh921ify]

Can't u put your different colors on hot keys like 1 2 or 3

[@rajendrakumarmakwana8941]

God 😇🙏👼 bless you l All😃😃😃

[@jhakimi69]

why didnt you just mention intermediate filaments as well? probably would have added another 2 minutes along with the microtubules as well as what they are composed of

[@shubhamsarkar3591]

Says 6-7 'nano'metres, biologists call it 'micro'filament

[@radusoldan1340]

Cells have a skeleton how cool is that :D

SBHAN ALLA human is enough proof for god existence, how after you sew all of this amazing perfection in our cell which is the smallest dynamic entity! in our creation you still think “It dovlept by it is self or it has started from nothing!!” you guys don’t see your self that’s crazy give it a thought, ISLAM
