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

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

[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.

[hollyberi]

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

[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.

[adelasefora]

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

[ym.]

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

[samuelgreenrod]

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

[radusoldan]

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 ?

[joshboston]

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

[Marisol]

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

[thequickestway]

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.

[shewanabeysinghe]

khan academy is so valuable to everyone

[AnonnymouZ]

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

[izpotter]

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

[dilipprakash]

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

[Jose-txyx]

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.

[sheylasm]

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

[tonyc]

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

[deoklingz__]

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

[shubhamsarkar]

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